The port to use ClutterPaintNodes basically mirrors what
it currently does, with the major benefit of not depending
on cogl_get_draw_framebuffer() anymore.
There are various factors that influence the number of
subnodes:
* The background color adds a color subnode;
* The selection adds a clip subnode, and a color subnode,
or a color and a text subnode;
The simplest case is when the text does not overflow and
has no background color nor selection. In that case, the
render tree is simply:
[ Dummy ]
↓
[ Text ]
In contrast, the most complex case is when drawing the text
with selection, in which case the render tree looks like:
[ Dummy ]
↓
[ Clip ]
↓
[ Text ] → [ Clip ]
↓
[ Color ] → [ Text ]
Since the selection may have another text color, the selected
text must be rendered again, but clipped to only cover the
selection rectangle. This is suboptimal, but it's what the
current code already does anyway.
When painting a ClutterText, there are two different aspects that
should be taken into account:
1. The allocated size of the actor; and
2. The reported size of the PangoLayout, which may be smaller or
bigger than (1)
When (2) is bigger than (1), ClutterText has to clip the text to
only draw at the visible contents over the actor surface. In
addition to that, ClutterText also tracks the cursor position,
which makes clipping a bit more complicated.
The current ClutterTextNode.draw() implementation assumes that
the (1) also represents (2), which is not true. This makes
clipping not work.
Fix that by assuming that the position to draw the PangoLayout
is passed as the second rectangle, and the actor size is the
first one.
To avoid a known race condition in the wl_output protocol documented in
https://phabricator.freedesktop.org/T7722, mutter delays the `wl_output`
destruction but nullify the `logical_monitor` associated with the
`wl_output` and the binding routine `bind_output()` makes sure not to
send wl_output events if the `logical_monitor` is `NULL` (see commit
1923db97).
The binding routine for `xdg_output` however does not check for such a
condition, hence if the output configuration changes while a client is
binding to xdg-output (typically Xwayland at startup), mutter would
crash while trying to access the `logical_monitor` which was nullified
by the change in configuration.
Just like `bind_output()` does for wl_output, do not send xdg-output
events if there is no `logical_monitor` yet.

Changes in window decoration result in the window being reparented
in and out its frame. This in turn causes unmap/map events, and
XI_FocusOut if the window happened to be focused.
In order to preserve the focused window across the decoration change,
add a flag so that the focus may be restored on MapNotify.
Closes: #273
The compositor will automatically unredirect the top most window which
is fully visible on screen. When unredirecting windows, it also shapes
the compositor overlay window (COW) so that other redirected windows
still shows correctly.
The function `get_top_visible_window_actor()` however will simply walks
down the window list, so if a window is placed on a layer above and
unredirected, then iconified by the client, it will still be picked up
by `get_top_visible_window_actor()` and he compositor will reckon it's
still unredirected while not in a visible state anymore, thus leaving a
black area on screen.
Make sure we skip the windows not known to the compositor while picking
the top visible window actor to avoid this issue.

Previously, trackballs were detected based on the presence of the
substring "trackball" in the device name. This had the downside of
missing devices, such as the Kensington Expert Mouse, which don't have
"trackball" in their names.
Rather than depending on the device name, use the ID_INPUT_TRACKBALL
property from udev to determine whether or not to treat a device as a
trackball.
This adds a new function, `is_trackball_device`, to MetaInputEvents, and
eliminates the `meta_input_device_is_trackball` function.

If an effect is active and it overrides the paint volume, we should
always recompute the paint volume when requested and not use the
cache, since the paint volume override can change from call to
call depending on what phase of painting we are in. For instance,
if we are part way through painting effects and request the
paint volume, the paint volume should only go up to the current
effect, but in a later call to compute repaint regions, the
paint volume needs to expand to accomadate the effect.
This still involves a lot of recomputation in the case of effects -
in a later clutter version it would be worth adding an API to
allow effects to explicitly recompute and return a new the paint
volume up to the current effect as opposed to recomputing
the cached one.
Previously we were checking l->data != NULL || (l->data != NULL &&
l->data != priv->current_effect). This would continue the loop even
if l->data == priv->current_effect, since l->data != NULL, which was
not the intention of that loop.
We also don't need to check that l->data != NULL before checking if
it does not match the current_effect, since we already checked
that current_effect was non-NULL before entering the loop.
On Wayland, xdg-foreign would leave a modal dialog managed even after
the imported surface is destroyed.
This is sub-optimal and this breaks the atomic relationship one would
expect between the parent and its modal dialog.
Make sure we unmanage the dialog if transient_for is unset even for
Wayland native windows.

Some tablets have a noticable pointer jump on tip down/up, causing unintended
lines during drawing. Likewise, a button event may have an axis update that we
currently ignore. libinput provides tablet axis events only if no other state
changes, the client must instead get the current axis data from the tip/button
event. So let's do this, process the event axis data during tip/button as
well.

Two other helper methods have been added so the virtual device can fetch
the current keyboard group, and latch modifiers for key emission. Combining
all this, the virtual device is now able to handle keycodes in further
levels.

A window placed using a placement rule should keep that relative
position even if the parent window moves, as the position tied to the
parent window, not to the stage. Thus, if the parent window moves, the
child window should move with it.
In the implementation in this commit, the constraints engine is not
used when repositioning the children; the window is simply positioned
according to the effective placement rule that was derived from the
initial constraining, as the a xdg_popup at the moment cannot move
(relative its parent) after being mapped.

A window can be unmanaged without asking the client to do it, for
example as a side effect of a parent window being unmanaged, if the
child window was a attached dialog.
This means that the client might still make requests post updates to it
after that it was unmapped. Handle this gracefully by NULL-checking the

reassign it the toplevel role, or reset the xdg-toplevel, both resulting

A popup can be reset, and when that happens, window and actor are
destroyed, and won't be created again unless it is reassigned the
popup role.
If a client queued frame callbacks when resetting a popup, the frame
callbacks would be left in the pending state, as they were not queued on
the actor, meaning we'd hit an assert about the frame callbacks not
being handled. Fix this by caching them on the MetaWaylandSurface, so
that they either are cleaned up on destruction, or queued on the actor
would the surface be re-assigned the popup role.
https://gitlab.gnome.org/GNOME/mutter/issues/240
Sometimes it may be useful for roles to put callbacks in the generic
surface frame callback queue. The surface frame callback queue will
either eventually be processed on the next surface role assignment that
places the frame callbacks in a role specific queue, processed at some
other point in time by a role, or cleaned up on surface destruction.

When a xdg-toplevel is reset, the window and actor are recreated, and
all state is cleared. When this happened, we earlied out from the
xdg-toplevel commit handler, which would mean that if the client had
queued frame callbacks when resetting, they'd be left in the pending
commit state, later hitting an assert as they were not handled.
Fix this by queuing the frame callbacks no the new actor, so that they
are emitted whenever the actor is eventually painted.

This was done for input regions in commit 718a89eb2f (Thanks Jonas
for the archaeology!) but opaque regions follow the same scaling.
This brings less evident issues as opaque regions are just used for
culling optimizations.
Commit 6a92c6f83 unintendedly broke input/opaque region calculations
on hidpi. Most visible side effect is that clicking is only allowed
in the upper-left quarter of windows.
The surface coordinates are returned in logical unscaled buffer
size. We're however interested in actor coordinates (thus real
pixels) here.
As it is a bit of a detour how the scale to be applied is calculated,
refactor a meta_wayland_actor_surface_get_geometry_scale() function
that we can use it here, and use it consistently for surface size and
the given regions.
Commit a3da4b8d5b changed updating of
window monitors to always use take affect when it was done from a
non-user operation. This could cause feed back loops when a non-user
driven operation would trigger the changing of a monitor, which itself
would trigger changing of the monitor again due to a window scale
change.
The reason for the change, was that when the window monitor changed due
to a hot plug, if it didn't actually change, eventually the window
monitor pointer would be pointing to freed memory.
Instead of force updating the monitor on all non-user operations, just
do it on hot plugs. This allows for the feedback loop preventing logic
to still do what its supposed to do, without risking dangling pointers
on hot plugs.

As per specification
> The compositor ignores the parts of the input region that
> fall outside of the surface.
> The compositor ignores the parts of the opaque region that
> fall outside of the surface
This fixes culling problems under certain conditions.
`ClutterText` painting for editable single_line_mode actors like `StEntry`
is always clipped by:
`cogl_framebuffer_push_rectangle_clip (fb, 0, 0, alloc_width, alloc_height)`
So it's difficult to get the rectangle wrong. However in cases where the
target framebuffer has changed (`cogl_push_framebuffer`) such as when
updating `ClutterOffscreenEffect` we had the wrong old value of `fb`. And
so would be clipping the wrong framebuffer, effectively not clipping at all.
Currently xdg-shell applies a geometry set with set_window_geometry
unconditionally. But the specification requires:
> When applied, the effective window geometry will be
> the set window geometry clamped to the bounding rectangle of the
> combined geometry of the surface of the xdg_surface and the
> associated subsurfaces.
This is especially important to implement viewporter and
transformation.
By using the shm file when sending the keymap to all clients, we
effectively allows any client to change the keymap, as any client has
the ability to change the content of the file. Sending a read-only file
descriptor, or making the file itself read-only before unlinking, can
be worked around by the client by using chmod(2) and open(2) on
/proc/<pid>/<fd>.
Using memfd could potentially solve this issue, but as the usage of
mmap with MAP_SHARED is wide spread among clients, such a change can
not be introduced without causing wide spread compatibility issues.
So, to avoid allowing clients to interfere with each other, create a
separate shm file for each wl_keyboard resource when sending the
keymap. We could eventually do this per client, but in most cases,
there will only be one wl_keyboard resource per client anyway.

If a client maps a popup in response to a key-down event, but the
mapping doesn't occur until after the user has already released the same
button, we'd immediately dismiss the popup. This is problematic, as one
often presses and releases a key quite quickly, meaning any popup mapped
on key-down are likely to be dismissed.
Avoid this race condition by accepting serials for key down events, if
the most recent key-up event had the same keycode.

For historical reasons meta_monitor_is_active() checked whether it is
active by checking whether the main output have a CRTC assigned and
whether that CRTC has a current mode. At a later point, the MetaMonitor
got its own mode abstraction (MetaMonitorMode), but
meta_monitor_is_active() was never updated to use this.
An issue with checking the main output's CRTC state is that, if there is
some CRTC mode combination that for some reason isn't properly detected
by the MetaMonitorMode abstraction (e.g. some tiling configuration not
yet handled), meta_monitor_is_active() would return TRUE, even though no
(abstracted) mode was set. This would cause confusion here and there,
leading to NULL pointer dereferences due to the assumption that if a
monitor is active, it has an active mode.
Instead, change meta_monitor_is_active() to directly check the current
monitor mode, and log a warning if the main output still happen to have
a CRTC with a mode assigned to it. This way, when an not undrestood CRTC
mode combination is encountered, instead of dereferencing NULL pointers,
simply assume the monitor is not active, which means that it will not be
managed or rendered by mutter at all.

We refuse to move focus while a grab operation is in place. While this
generally makes sense, there's no reason why the window that owns the
grab shouldn't be given the regular input focus as well - we pretty
much assume that the grab window is also the focus window anyway.
In fact there's a strong reason for allowing the focus change here:
If the grab window isn't the focus window, it probably has a modal
transient that is focused instead, and a likely reason for the focus
request is that the transient is being unmanaged and we must move
the focus elsewhere.

Add API to let GNOME Shell have the ability to get notified about remote
access sessions (remote desktop, remote control and screen cast), and
with a way to close them.
This is done by adding an abstraction above the remote desktop and
screen cast session objects, to avoid exposing their objects to outside
of mutter. Doing that would result in external parts holding references
to the objects, complicating their lifetimes. By using separate wrapper
objects, we avoid this issue all together.
The docs previously suggested that `cogl_frame_info_get_frame_counter`
returned a timestamp of an unknown clock ID. That's not correct. The
cogl source code shows that it does and must use the same clock as
`cogl_get_clock_time`.

Monitor whether UPower is running ourselves. That allows us to keep the
same value for "lid-is-closed" throughout the process of UPower
restarting, preventing unwanted monitor re-configuration through the process.
Fixes another screen black out when UPower restarts and the laptop lid
is closed.
Rather than handle UpClient in both MetaBackend (to reset the idletime
when the lid is opened), and in MetaMonitorManager and
MetaMonitorConfigManager (to turn the screen under the lid on/off
depending on its status), move the ability to get the lid status from
UPower or mock it in one place, in MetaBackend.
Restarting UPower will make every property of UpClient emit a "notify"
signal (as a GDBusProxy would). Avoid mutter reconfiguring the displays
when upower restarts by caching the last known value of "lid-is-closed"
and only reconfiguring the displays if it actually changed.
This fixes a black out of the screen when UPower restarts.
Previously we relied on the test-client to make sure that a window was
shown. For X11, we did not need to do anything, but for Wayland we had
to make sure we had drawn the first frame, otherwise mutter wouldn't
have a buffer making the window not showable.
Doing it this way doesn't work anymore however, since the 'after-paint'
event will be emitted even if we didn't actually paint anything. This is
the case with current Gtk under Wayland, where we won't draw until the
compositor has configured the surface. In effect, this mean we'll get a
dummy after-paint emission before the first frame is actually painted.
Instead, move the verification that a "show" command has completed by
having the test-runner wait for a "shown" signal on the window, which is
emitted in the end of meta_window_show(). This requires an additional
call to gdk_display_sync() in the test-client after creating the window,
to make sure that the window creation vents has been received in the
compositor.
As of "stack-tracker: Keep override redirect windows on top"
(e3d5bc077d), we always sorted all
override redirect on top of regular windows, as so is expected by
regular override redirect windows. This had an unwanted consequence,
however, which is that we should still not sort such override redirect
windows on top if they are behind the guard window, as that'd result in
windows hidden behind it now getting restacked anyway.
Fix this by only sorting the override redirect windows that are found
above the guard window on top. This fixes the override-redirect stacking
test.
The special ::pick implementation there makes clutter fall into paths
that do require a get_paint_volume() implementation, or an infinite
area will be used.
Providing a paint volume here is easier on the invalidation mechanism.
This optimization was presumably added before Clutter was able to
invalidate selected regions of an actor. Paint volumes are supposed
to be invariable as long as the actor conditions don't change.
Stacking of other actors shouldn't affect the paint volume, so it's
actually wrong to optimize those areas away here.
The framerate for screen cast sources was set to variable within 1 FPS
and the framerate of the monitor being screen casted. This meant that if
the sink didn't match the framerate (e.g. had a lower max framerate),
the formats would not match and a stream would not be established.
Allow letting the sink clamp the framerate range by setting it as
'unset', allowing it to be negotiated.
The PipeWire master branch saw some backports from the work branch,
including API changes making the 0.1 series more aligned with future

that existed in the older version.
xdg-foreign clears the `transient_for` of a modal dialog when its

against its parent.

e.g. creating a couple of temporary X11 connections, and on disconnect,
if they happen to be the last client, the X server will terminate
itself.
https://bugzilla.gnome.org/show_bug.cgi?id=759538
Under Xorg the cursor size preference was pre-scaled originating from
gtk, while with Wayland it came directly from GSettings remaining
unscaled. Under Xwayland this caused the X11 display code to set the
wrong size with HiDPI configurations, which was often later overridden
by the equivalent code in gtk, but not always.
Fix this by always having the cursor size preference unscaled, scaling
the size correctly where it's used, depending on how it's used.

Split X11 specific parts into MetaX11Display. This also required

For some reason "backends: Remove X11 idle-monitor backend" removed
unrelated warning messages for when generated monitor configurations
that should work didn't, which also made the unit tests fail.
This commit adds them back, which also makes the tests pass again.
Commit 22723ca37 moved buffer realization to
meta_wayland_surface_commit() so that it wouldn't be part of
meta_wayland_buffer_attach().
However, creation of dmabuf buffers would call into
meta_wayland_buffer_attach() directly without realizing the buffer
first. attach() would then fail and mutter would effectively shut down
any clients using the zwp_linux_dmabuf protocol (note that if such
client was Xwayland, mutter itself would shut down as well).
Add the missing bit in order to make zwp_linux_dmabuf protocol work
again.
One of the current limitations of EGLStreams is that there's no way to
resize a surface consumer without re-creating the entire stream.
Therefore, while resizing, clients will send wl_surface::attach requests
so the compositor can re-create its endpoint of the stream, but no
buffer will be available actually. If we proceed with the rest of the
attach operation we'll be presenting an empty buffer.
In order to fix this, a separate wl_eglstream_controller protocol has
been introduced that clients can use to request a stream re-creation
without overloading wl_surface::attach for that purpose.
This change adds the required logic to create the corresponding
wl_eglstream_controller global interface that clients can bind to.
Whenever a client requests a stream to be created, we just need to
create and realize the new EGLStream buffer. The same buffer resource
will be given at a later time to wl_surface::attach, whenever new
content is made available by the application, so we can proceed to
acquire the stream buffer and update the surface state.
https://bugzilla.gnome.org/show_bug.cgi?id=782575
Clients using EGLStream-backed buffers will expect the stream to be
functional after wl_surface::attach(). That means the compositor-side
stream must be created and a consumer attached to it.
To resolve the above, this change realizes buffers even when the attach
operation is deferred (e.g. synchronized subsurfaces).
https://bugzilla.gnome.org/show_bug.cgi?id=782575
When dealing with synchronized subsurfaces, we defer buffer attachments
until the parent surface state is applied.
That causes interaction issues with EGLStream backed buffers, as the
client expects the compositor-side stream to be functional after it
requests a wl_surface::attach.
By allowing the compositor to realize buffers without attaching them, we
could resolve the issue above if we define a realized EGLStream buffer
as a functional EGLStream (EGLStream + attached consumer).
This change moves the texture consumer creation part from the attach
function to the realize one.

Commit 712ec30cd9 added the logic to only
choose EGL configs that match the GBM_FORMAT_XRGB8888 pixel format.
However, there won't be any EGL config satisfying such criteria for
non-GBM backends, such as EGLDevice.
This change will let us choose the first EGL config for the EGLDevice
backend, while still forcing GBM_FORMAT_XRGB8888 configs for the GBM
one.

Where to realize a hardware cursor depends on where on the screen it
will be displayed. For example it only needs buffers for the cursor
plane on a certain GPU if it overlaps with a monitor that is connected
said GPU.
Previously, we were too eager with uploading the cursor plane buffers,
which in effect resulted in the secondary GPU always being woken up
when changing the cursor, even though the cursor plane would actually
never be set unless the pointer cursor was moved to a monitor connected
to the secondary GPU. These wake-ups caused noticable stuttering; thus
by uploading the buffers more lazilly, the stuttering is avoided.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/77
When a cursor is hidden, the native backend will properly hide the HW
cursor sprite as well, but it would communicate this as if the cursor
was not handled by the backend, while in fact it still was. This caused
the generic cursor rendering layer to queue a redraw.

When force-updating the HW state we might end up with a situation where
the HW cursor is no longer usable. If this would happen, we'd before

drmModeAddFB2 allows userspace to specify a real format enum on
non-ancient kernels, as an improvement over the legacy drmModeAddFB
which derives format from a fixed depth/bpp mapping.
As an optimisation, Weston used to decide at the first failure of
drmModeAddFB2 that the ioctl was unavailable: as non-existent DRM
ioctls return -EINVAL rather than -ENOSYS or similar, bad parameters are
not distinguishable from the ioctl not being present.
Mutter has also implemented the same optimisation for dumb framebuffers,
which potentially papers over errors for the gain of avoiding one ioctl
which will rapidly fail on ancient kernels. Remove the optimisation and
always use AddFB2 where possible.

And ensure the actor is no longer reactive even though it might live longer
because of close effects, GCs, and whatnot. This ensures the actor is not
eligible for pointer picking within the destruction of its surface.
Closes: #188
The MetaCloseDialog implementation object may stay artifically alive
for a longer period. This was usually fine till gnome-shell commit
b03bcc85aad, as the check_alive() timeout will keep running even
though the window went unmanaged/destroyed, leading to crashes.
In order to fix this, forcibly hide the dialog if it is visible and
the window is being unmanaged, so the timeout is stopped in time.
The order of role creation is undetermined, so we can't account that
the parent surface will have a role (and an actor) at the time of
creating the wl_subsurface role for a child surface.
So we must do it both ways, add the subsurface as a child on
get_subsurface() if the parent already got a role, and lazily add
child subsurface actors to the current one if the parent surface got
it at a later point.

Who knows what bugs this may have caused...
Treat the main seat as other seats, so we don't have to handle it differently
in specific places. This was already the case before when a real device
was plugged before the startup, but not applied when hotplugging a device.
When no input devices are available on startup the device manager might be fast
enough to be constructed so that no default stage is set yet, and thus when
main seat virtual devices are created they won't have a proper stage set.
If then we plug a real device, the events that an input manager could generate
won't be associated to any stage and thus won't be processed.
We need then ensure that when we update the stage for the device manager we
(un)associate it also to the main seat devices.
Commit 47131b1d ("frames: Handle touch events") introduced an assert to

After 20176d03, the Wayland backend only synchronizes with the
compositor after a geometry was set, and it was different from
the current geometry.
That commit was mistakenly comparing the geometry before chaining
up, which would yield a false negative on the case where the
client didn't call set_geometry() before commit().
Fix that by caching the old geometry locally, chain up (and thus
apply the new geometry rectangle), then comparing the old and
current geometry rectangles.

This avoids overwhelming the GPU with trying to update mipmaps at a high
rate. Because doing so could easily cause a reduction in the compositor
frame rate and thus actually reduce visual quality.
In the case of a window that is constantly animating in the overview,
this reduces mutter's render time by around 20%-30%.
In devices such as ARM boards there could be no input devices connected on
startup, leading to a crash when we try to process artificial events that
could be queued (as gnome-shell does when syncing pointer).
Those events still should refer to a device and, in case we don't have one
provided by libinput we should still return the core devices defined in the
main seat.
This is just done on wayland as it'll break horribly on X11, we let
this happen through pointer emulated events in XISelectEvents evmask
instead.
Some things had to be made slightly more generic to accomodate touch
events. The MetaFrames shall lock onto a single touch at a time, we

We require logind for the native backend, but the backend itself is
optional. However since commit 06c357d78, we will always throw an

As we still support "auto" - that is, whether the native backend is
enabled depends on whether its dependencies are available - the
easiest option is to make sure we always include either elogind or
libsystemd in the dependency check rather than erring out explicitly
if neither is found.

To check if a subsurface is effectively synchronized, we walk the
subsurface hierarchy to look for a non-subsurface parent or a subsurface
being synchronized.
However, when client is closing, the parent surface might already be
gone, in which case we end up with a surface being NULL which causes a
NULL pointer dereference and a crash.
Check if the parent surface is NULL to avoid the crash, and consider
it's already synchronized if it is NULL to avoid further updates.

The current implementation of the XdgSurface v6 protocol does not check
if the window changed before calling meta_window_wayland_move_resize().
The problem with this approach is that calling this function is a costly
operation since we enter the compositor side. In GNOME Shell case, it is
in JavaScript, which triggers a GJS trampoline. Calling this function on
every mouse movement is naturally as terrible as it could be - and is
exactly what happens now.
This commit adds the necessary checks to only call move_resize() when
the window actually changed, or when it needs to be updated.
https://bugzilla.gnome.org/show_bug.cgi?id=780292
Issue: #78
This will be used by the next commit to determine when a window
geometry change should be ignored or not. Normally, it would be
enough to just check if the position and sizes changed.
The position, in this case, is relative to the client buffer, not
the global position. But because it is not global, there is one,
admitedly unlikely, situation where the window state is updated
while the client size and relative positions don't change.
One can trigger this by e.g. tiling the window to the half-left of
the monitor, then immediately tile it to half-right. In this case,
the window didn't change, just it's state, but nonetheless we need
to notify the compositor and run the full move/resize routines.
When that case happens, though, the MetaWindowWayland is tracking
the pending state change or a move. And this is what we need to
expose.

Issue: #78
In the old, synchronous X.org world, we could assume that
a state change always meant a synchronizing the window
geometry right after. After firing an operation that
would change the window state, such as maximizing or
tiling the window,
With Wayland, however, this is not valid anymore, since
Wayland is asynchronous. In this scenario, we call
meta_window_move_resize_internal() twice: when the user
executes an state-changing operation, and when the server
ACKs this operation. This breaks the previous assumptions,
and as a consequence, it breaks the GNOME Shell animations
in Wayland.
The solution is giving the MetaWindow control over the time
when the window geometry is synchronized with the compositor.
That is done by introducing a new result flag. Wayland asks
for a compositor sync after receiving an ACK from the server,
while X11 asks for it right away.

When deriving the global scale directly from the current hardware state
(as done when using the X11 backend) we are inspecting the logical
state they had prior to the most recent hot plug. That means that a
primary monitor might have been disabled, and a new primary monitor may
not have been assigned yet.
Stop assuming a primary monitor has an active mode before having
reconstructed the logical state by finding some active monitor if the
old primary monitor was disabled. This avoids a crash when trying to
derive the global scale from a disabled monitor.

As a follow up to the patch from a95cbd0a, we need to make sure
that the pointer is out of the way as well when monitors changed,
since that's the event that will prevail in some cases. Besides,

which initialized the pointer position in the same way both in
this case and in the real_post_init() function.

We used to maintain an actor for cursors, even though we would possibly
use hw overlays or even some other overlay actor for those. This happens
no more, so check whether we are dealing with an actor-backed surface role
before fiddling with it.
All surface roles that do need a backing actor inherit from this
class, it makes sense to move actor management there. This also
means the MetaWaylandActorSurface is in charge of emitting
::geometry-changed on the MetaWaylandSurface.
Instead of scheduling a meta_later, keep track of the unassociated
windows, and look for matches as soon as the MetaWaylandSurface is
created on our side.
This will ensure the surface is given the Xwayland role before receiving
the first wl_surface.commit.
In the synchronized subsurface case, the destination list may
contain other elements from previous wl_surface.commit calls.
Resetting the list will leave those dangling frame callbacks
that will lead to invalid writes when those get to be destroyed
(eg. on client shutdown).
The fix is twofold. On one hand, it makes sense not to relate IM (nor
any other) generated events to a HW device. On the other hand, if we
are unfortunate that an IM event is in flight when we are switching
to another TTY, it may arrive at a time when the source device is no
longer existent.

Centering the pointer at startup causes undesired behaviour if
it ends up hovering over reactive elements, that might react
to that positioning, causing confusion. This is the case of
the login dialog when a list of different users is shown, as
centering the pointer at startup in that case will get the
user in the center of the screen pre-selected, which is not
the expected behaviour (i.e. pre-selecting the first one).
Fix this by simply moving the pointer out of the way, close

Right now if Xwayland crashes, we crash, too.
On some level that makes sense, since we're supposed to control the
lifecycle of Xwayland, and by it crashing we've lost that control.
But practically speaking, the knock-on crash adds noise to the logs,
bug trackers, and retrace servers that only makes debugging harder.
And the crash isn't something mutter can "fix", since it's
ultimately from a bug in Xwayland anyway.
This commit makes mutter exit instead of crash if Xwayland goes away
unexpectedly.
Right now we explicitly g_clear_error any error we find, but that
makes it tricky to return early from the function, which a
subsequent commit will want to to do.
This commit switches GError to use g_autoptr so the error clearing
happens automatically.
This is a small mistake spotted while working on a solution

When moving the pending state of an effectively synchronized subsurface

overwriting the struct.
The other approach had 2 kind of leaks, one that would happen everytime
a wl_surface.commit happens on a sync subsurface (both surface/buffer
damage regions are leaked). The other more unlikely one would apply on
the rest of pending state data, happening whenever the compositor gets
>1 wl_surface.commit calls on the subsurface before the parent surface
gets its own.
The function has also been renamed to use the more descriptive "merge"

When using two monitors size by side with different scales, once the
cursor moves from one output to another one, its size changes based on
the scale of the given output.
Changing the size of the cursor can cause the cursor area to change
output again if the hotspot is not exactly at the top left corner of the
area, causing the texture of the cursor to change, which will trigger
another output change, so on and so forth causing continuous surface
enter/leave event which flood the clients and eventually kill them.

But texture swizzling works by changing parameters before fragment shaders
and reading pixels from an already drawn FBO/texture doesn't involve those.
This should thus use pixel_format_to_gl_with_target(), which will result in
correctly requesting the same pixel format than the underlying texture,
while still considering it BGRA for the upper layers in the swizzling case.

This state tracks hardware devices' state, thus shouldn't be triggered by
events that were emulated/forwarded by the IM. Those may include modifiers
and would result in xkb_state being doubly set, and possibly stuck.

Actor keybindings were dispatched in an earlier return path, which means
the IM doesn't get to see certain key events. Flip the order around so the
IM has an opportunity to handle all keypresses.

Raising and lowering windows in tandem without a proper grouping
mechanism ended up being more annoying than functional.
This reverts commit e76a0f564c.
We just arbitrarily chose the first EGL config matching the passed

When painting the titlebar, button icons that aren't available in the
desired size need to be scaled. However the current code inverses the
scale factor, with the result that the adjusted icons are much worse
than the original icons, whoops.
This went unnoticed for a long time given that most icons are availa-
ble in the desired 16x16 size, and the most likely exceptions - window
icons - are not shown by default.

In order to let applications gracefully handle version mismatches, add
a version property to the APIs. Also add a warning on the APIs that
these are not meant for public consumption.
If the coordinates was for a stream not at the stage position (0, 0),
they'd be incorrect. Fix this by correctly translating the coordinates
according to the stream position.
IF two touch devices have colliding touch point IDs they'd interfere on
the seat. To avoid this, always allocate a seat wide slot for each
device wide slot, but don't use device slots directly in the seat.
Make the Wayland objects push the state relevant to their role to the
MetaSurfaceActor instead of MetaSurfaceActorWayland pulling the state
from the associated surface.
This makes the relationship between the actor and the objects that
constructs it more clear; the actor is a drawable that the protocol
objects control, not the other way around.
This will make it easier to "detach" a surface actor from a surface,
which is necessary when unmapping a window while the underlying surface
is yet to be destroyed and potentially reused.

This commit moves out non-core wl_surface related code into separate
code units, while renaming types to fit a common scheme. The changes
done are:
* ClutterActor based surface roles built upon
MetaWalyandSurfaceRoleActorSurface. This object has been renamed to
MetaWaylandActorSurface and related functionality has moved into
meta-wayland-actor-surface.c.
* The code related to roles backed by a MetaWindow (i.e. built upon
MetaWaylandShellSurface) was moved into meta-wayland-shell-surface.c
* The majority of subsurface related code was moved into into
meta-wayland-subsurface.c and the object was renamed
MetaWaylandSubsurface.

mutter would discard the shape region set by the client if its matches
the entire client area in meta_window_x11_update_shape_region().
However, if the window is later resized (maximized or other), the
compositor will fail to update the shape region properly for undecorated
windows because the shape region was discarded, which causes black areas
to appear in place of the updated areas.
If the client window is undecorated, keep the shape region even if when
it matches the client area.

When the buffer modifier is DRM_FORMAT_MOD_LINEAR, we can use the
old code path. That means not specifying any modifier parameter.
It was an issue when the primary GPU was creating a linear GBM surface
and that a secondary GPU (not supporting modifiers) was trying to
import it. It was failing because the driver could not use the
import_modifiers extension even though it could in theory easily
import the buffer.
https://gitlab.gnome.org/GNOME/mutter/issues/18
We were retrieving the supported KMS modifiers for all GPUs even
though what we really need to intersect between these sets of

primary GPU used for rendering);
3) GBM supported modifiers when creating the surface (already
taken care of by gbm_surface_create_with_modifiers());

Checking correct state is responsibility of the ClutterInputFocus user, and
it is indeed possible to get a focused ClutterText while its
ClutterInputFocus didn't get itself focused (eg. lack of IM).
https://gitlab.gnome.org/GNOME/mutter/issues/36Closes: #36
If text_input_enable() is called when there no active IM (eg. running plain
mutter), some ClutterInputFocus method calls that are not allowed while
unfocused will end up called, triggering critical warnings.
If there is no IM return early here, all other calls are superfluous then.
We currently don't handle NULLs on these correctly, yet they can be
so when running nested. Just refrain from sending those wp_tablet(_pad)
events in that case.
The property has been 32 bits since around 2011 and has not changed, mutter
expects it to be 8 bits. The mismatch causes change_property to never
actually change the property.

Plain input stream read() calls don't provide hard guarantees about
the number of bytes read, but the async method callback sort of

This is actually the behavior of g_input_stream_read_all(), so

On drivers that do not support glGetTexImage2D (i.e. on GLES),
cogl_texture_get_data() has a "feature" that allows it to download
texture data by rendering the texture on an intermediate framebuffer
object and then reading back the data from there. However, this
feature requires the user to have previously set an "active"
framebuffer object in the context, which makes this very tricky
because it is not clear to the developer that he needs to do that
in order for some code to work on GLES (of course it works on
desktop GL, so nobody notices...) and additionally the code actually
crashes if an active fbo is not set!
This patch basically removes this feature in order to prevent
the crash and is in line with how this code has evolved in cogl-2.0:

The shortcut inhibitor protocol states that the “active” event should be
sent every time compositor shortcuts are inhibited on behalf of the

Send the “active” event unconditionally to match the protocol
definition.

There seems to be a kernel race when one disconnects an external
monitor connected to a DisplayPort via a USB-C adapter. The race
results in a connector being reported as connected, but without any
modes supported.
This had the side effect that we tried to set a preferred mode to
the first listed mode, but as no modes were available, we instead tried
to dereference the first element of a NULL array, causing a
segmentation fault.
Mitigate this by skipping adding output if no supported modes are
advertised and the output doesn't support scaling, while moving the
fallback path for calculating a preferred output mode to after possibly
adding the common modes, to avoid the unvolentary NULL dereference.

Opening and closing the device may result into XI2 grabs being cut short,
resulting into pad buttons being rendered ineffective, and other possible

The tertiary-button-action (see bug 790028) is a place for g-c-c to store

BTN_STYLUS3 is defined by the Linux 4.15 kernel and is sent when the

When a window's workspace is not NULL, on_all_workspace should be FALSE.
Similarly, when on_all_workspace is TRUE, the window workspace should be
NULL.
This is an assumption in multiple places in the code, including when
setting the workspace state, the window is either added or removed from
all workspaces only if the window's workspace is NULL.
This rule is initially enforced at creation in _meta_window_shared_new()
when a initial workspace is set. However, when the initial workspace is
set from the session info, the initial workspace is not marked as “set”
which leads to an assertion failure when unmanaging windows, because the
window is not removed from all the workspaces.
When applying the session info to a window, mark the workspace as “set”.
https://gitlab.gnome.org/GNOME/mutter/issues/4Closes: #4
Having “on_all_workspaces_requested” FALSE on a window does not imply a
workspace is set.
If the X11 window is placed on a secondary monitor while workspaces
applies on primary monitor only (“workspaces-only-on-primary” set) then
“on_all_workspaces_requested” is FALSE while “on_all_workspaces“ is TRUE
and the associated workspace is NULL, leading to a crash when saving the
gnome-shell/mutter session.
So if no workspace is set, use the “initial_workspace” instead to avoid
a NULL pointer dereference.

Now that we have the list of supported modifiers from the monitor
manager (via the CRTCs to the primary planes), we can use this to inform
EGL it can use those modifiers to allocate the GBM surface with. Doing
so allows us to use tiling and compression for our scanout surfaces.
This requires the Mesa commit in:
Mesa 10.3 (08264e5dad4df448e7718e782ad9077902089a07) or
Mesa 10.2.7 (55d28925e6109a4afd61f109e845a8a51bd17652).

Using 800x600 as minimum logical size is very 4:3 thinking, while a lot of
modern devices are 16:9. The specific reason for this commit is to allow
1.5 scaling at mini-laptops (clamshell devices) with e.g. a 5.5"
1280x720 screen. Given that this device has a keyboard, one obviously
is not holding it very close to ones eyes and at 220 dpi that means the text
is too small at scale 1.0. For one real world example of such a device see:

This function returns TRUE if there is any preedit going on. This method
will be useful in gnome-shell where similar checks are performed on
StIMText actors.
Offer the text-input interface global, so it can be used by clients. The
MetaWaylandSeat will also let MetaWaylandTextInput intercept key events
before the keyboard interface handles those.
This is the implementation of the internal text-input protocol that will
be used to communicate IMs (to be implemented by gnome-shell) with clients.
The text_input protocol has its own focus expressed through enter/leave
events, that will typically follow the keyboard's.
The client will be able to communicate its current status (eg. focus state,
cursor rectangle in surface coordinates, text surrounding the cursor
position, ...) and will receive commands from the compositor (eg. preedit
text, committing a string, ...).
Whenever there is an active input method, the compositor will route key
events directly through it. The client will not receive wl_keyboard
events if the event is consumed by the IM.
ClutterInputFocus is an abstract object to be subclassed by UI actors and
the wayland interface and represents the user of an input method. It
represents the current focus of the input method, so all emitted signals
and public API hooks are expected to be called when the input method is
currently interfacing with the input focus.
ClutterInputMethod is an abstract class (to be implemented in the upper
layers) that represents the input method itself. Besides focus management
itself, all public API calls that would be called by the subclasses are
delivered through the current input focus.
Issuing a shortcut inhibit request for a surface without a window set
will lead to a crash when trying to show the shortcut inhibitor dialog.
In such a case, it's safer to deny the request.
https://bugzilla.gnome.org/show_bug.cgi?id=792599
The events might fall through if there's no corresponding active
pointer/keyboard/touch interface. Barring bugs this should be safe to do,
just a bit wasteful.
Libinput shall report those as having slot=-1, which gets mistakenly
translated into the special "NULL" ClutterEventSequence. Making those
events get a non-NULL sequence will make single touch devices work.
https://bugzilla.gnome.org/show_bug.cgi?id=792005
We might receive touch events for unknown touch points, for example
when starting mutter while touching the screen (resulting in no
touch-down event ever being received). Avoid crashing when this happens
by just dropping these events on the floor.

When maximizing a window, the previous location is saved so that
un-maximize would restore the same original window location.
However, if a Wayland client starts with a window maximized, the
previous location will be 0x0, so if we have to force placement in
xdg_toplevel_set_maximized(), we should update the location as well so
that the window is placed on the right monitor when un-maximizing.
For that purpose, add a new flag to force the update of the window
location, and use that flag from xdg_toplevel_set_maximized().
https://bugzilla.gnome.org/show_bug.cgi?id=783901
Wayland clients know their size better, so for Wayland we'd rather not
try to resize the client on un-maximize, but for this to work we need a
new MetaMoveResizeFlags.
https://bugzilla.gnome.org/show_bug.cgi?id=783901
When closing a window and showing a new one, the new one may not be
granted input focus until it gets a buffer on Wayland.
If another window is chosen to receive focus and raised on top of stack,
the newly mapped window is focused but placed underneath that other
window.
Meaning that for Wayland surfaces, we need to defer adding the window to
the stack until we actually get to show it, once we have a buffer
attached.
Rather that checking the windowing backend prior to decide if a window
is stackable or not, introduce a new vfunc is_stackable() which tells
if a window should be added to the stack regardless of the underlying
windowing system.
Also add meta_window_is_in_stack() API rather than checking the stack
position directly (replacing the define WINDOW_IN_STACK only available
in stack.c) and remove a window from the stack only if it is present
in the stack, so that the test in meta_stack_remote() becomes
irrelevant.

Wayland clients using the wl_shell interface were never receiving mouse
input. It meant they also couldn't be raised with a click.
This was because the call to meta_wayland_surface_set_window for wl_shell
surfaces did nothing while surface->window == window already. As such, it
never called clutter_actor_set_reactive() and the wl_shell window remained
a non-reactive actor.
Just make sure surface->window isn't already set before calling
meta_wayland_surface_set_window so it can actually do what it's meant to.

The device orientation coming out of iio-sensor-proxy defines upright/normal
as the direction in which the picture is displayed on the LCD panel without
any rotation. This is necessary for accelerometer rotation to work properly
in desktop environments which are not aware of panel-orientation issues.

rotation for the panel-orientation when we get rotation info from
iio-sensor-proxy.
https://bugzilla.gnome.org/show_bug.cgi?id=782294

If a LCD panel has a non normal orientation (mounted upside-down or 90
degrees rotated) then the kernel will report touchscreen coordinates with
the origin matching the native (e.g. upside down) coordinates of the panel.

non normal panel-orientation, we must apply the same transform to input
coordinates to keep the aligned.

Some x86 clamshell design devices use portrait tablet LCD panels while
they should use a landscape panel, resoluting in a 90 degree rotated

Newer kernels detect this and rotate the fb console in software to

orientation vs the casing in a "panel orientation" drm_connector property.
This commit adds support to mutter for reading the "panel orientation"
and transparently (from a mutter consumer's pov) fixing this by applying
a (hidden) rotation transform to compensate for the panel orientation.

The reason why multiple keycodes could be mapped to a single keysym was
to support having both KEY_FAVORITES and KEY_BOOKMARK map to
XF86Favorites. However, iterating through all layout levels adding all
key codes has severe consequences on layouts with levels that map
things like numbers and arrow. The result is that keybindings that
should only have been added for keycodes from the first level, are
replaced by some unexpected keycode where the same keysym was found on
another level.
An example of this is the up-arrow key and l symbol. Normally you'd find
both the up-arrow symbol and the l symbol on the first level and be done
with it. However, on the German Neo-2 layout, layout level 4 maps the
KEY_E to the l symbol, while layout level 4 maps KEY_E to up-arrow.
Which ever gets to take priority is arbitrary, but for this particular
case KEY_E incorrectly mapped to up-arrow instead of the l symbol,
causing the keyboard shortcut Super+l, which would normally lock the
screen, to trigger the workspace-up (Super+up-arrow) key binding.

This protocol is limited to Xwayland only and is not visible/usable by
any other client.
Mutter uses the following mechanisms to determine if an X11 client
should be granted a grab:
- is "xwayland-allow-grabs" set?
- if set, is the client blacklisted?
- otherwise, has the client set the X11 window property
_XWAYLAND_MAY_GRAB_KEYBOARD on the window using a client message?
- if not, is it a client white-listed either via the default system
list or the settings "xwayland-grab-access-rules"?
https://bugzilla.gnome.org/show_bug.cgi?id=783342
Add a new client message "_XWAYLAND_MAY_GRAB_KEYBOARD" that X11 clients
can use to tell mutter this is a well behaving X11 client so it may
grant the keyboard grabs when requested.
An X11 client wishing to be granted Xwayland grabs by gnome-shell/mutter
must send a ClientMessage to the root window with:
- message_type set to "_XWAYLAND_MAY_GRAB_KEYBOARD"
- window set to the xid of the window on which the grab is to be issued
- data.l[0] to a non-zero value
Note: Sending this client message when running a plain native X11
environment would have no effect.

The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).
This was added in wayland-protocols 1.10.

One scenario where this happened was one a system with one laptop
screen and one external monitor that was hot plugged some point after
start up. When the laptop lid was closed, the 'previous configuration'
being the configuration where only the laptop panel was enabled, passed
'is-complete' check as the number of configured monitors were correct,
and the configuration was applicable.
Avoid this issue by simply comparing the configuration key of the
previous configuration and the configuration key of the current state.
This correctly identifies a laptop panel with the lid closed as
inaccessible, thus doesn't incorrectly revert to the previous
configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=788915
When deriving the list of disabled monitors when creating new monitors
configs, don't include the laptop panel if the lid is currently closed,
as we consider the laptop panel nonexistent when the laptop lid is
closed when it comes to configuration.
The laptop panel connector(s) will either way be appropriately disabled
anyway, as the field listing disabled monitors in the configuration do
not affect actual CRTC/connector assignments.

If a parent doesn't have a window, it means it could have been
dismissed (for example due to a input serial race), but the more recent
popup might win the input serial race and try to map anyway. This would
result in a crash later on when trying to process the placement rule,
as the parent already has no window.

Move the top-most-popup correctness check to the finish_popup_setup()
function after checking the serial. If we pass the serial check, we

Also avoid failing a client that correctly set the top-most popup at map
time, but where at the time of processing the top most popup have
already been dismissed by the compositor for some arbitrary reason.

Commit b1a0bf891 broke the previous logic that we would only fallback
to the root cursor if 1) windows are not interactable or 2) no window
cursor is currently set (i.e. not hovering over any window). Now it
will set up the root cursor if it's NULL, which breaks clients
explicitly setting an invisible cursor. This commit restaurates the
previous behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
This function is supposedly not failable, so just move the theme_dirty
flag clearing to the beginning of the function. Protects against cases
where requesting a cursor image may result in it being loaded and set
as a texture, which emits ::texture-changed, which may end up requesting
the cursor image again.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
As wayland implements the cursor role, it consists of a persistent
MetaCursorSprite that gets the backing texture changed. This is
inconvenient for the places using MetaCursorTracker to track cursor
changes, as they actually track MetaCursorSprites.
This signal will be used to trigger emission of
MetaCursorTracker::cursor-changed, which will make users able to
update accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
Just like X11/XFixes behaves, the current cursor is not affected
by its visibility, so it can be queried while invisible (possibly
to be replaced).
For this, keep an extra effective_cursor pointer that will be
either equal to displayed_cursor (maybe a bit of a misnomer now)
or NULL if the cursor is invisible. The MetaCursorRenderer
management is tied to the former, and the ::cursor-changed signal
emission to the latter.

Adds a set of convenient functions that can be shared between x11 input

MetaWaylandKeyboard maintains its own xkb_state used to update Wayland
clients.
Add the necessary hooks to make sure the sticky keys modifier masks set

https://bugzilla.gnome.org/show_bug.cgi?id=788564
Implementing keyboard accessibility in clutter means we need to be able
to notify higher layers of possible modifier masks or setting changes
(as some keyboard accessibility can be disabled or enabled by keyboard).
For this purpose, add two new signals:
ClutterDeviceManager::kbd-a11y-mods-state-changed
ClutterDeviceManager::kbd-a11y-flags-changed
https://bugzilla.gnome.org/show_bug.cgi?id=788564
Use a set of bitwise enum flags to set different keyboard accessibility
features and the necessary vfunc hooks in clutter input device so that
keyboard preferences can be passed to different input device
implementations.
The idea is to be able to configure either the clutter own
implementation of keyboard accessibility for evdev, or eventually
configure AccessX from the X11 clutter input device using the same
mechanism.
https://bugzilla.gnome.org/show_bug.cgi?id=788564
On X11, when AccessX is enabled, all X11 clients benefit from the
AccessX features, including gnome-shell/mutter, meaning that special
keys like the overview or other shortcuts are also affected.
To achieve the same in Wayland, we need to implement the same features
in clutter main rather than the Wayland backend, so that all depending
code within the compositor but also Wayland clients (which rely on the
compositor to get keyboard events) similarly benefit from the
accessibility features.
Add hooks to the clutter main loop to be able to implement such
features.

Bluetooth mouse usually goes in sleep state after a timeout, when that
happen the mouse is disconnected and on_device_removed function is
called. Before the patch if a touch device is available the
on_device_removed function hide the cursor. The issue is that the cursor
does not reappear once the bluetooth mouse is reconnected because
MetaBackend::current_device_id is not invalidated when on_device_removed
was called.
The patch set MetaBackend::current_device_id to 0 if the current device
is removed. This will make update_last_device to be triggered as soon as
another input device is used or the bluetooth mouse reconnect, as
consequence that the cursor reappear. The id 0 is never given to devices
and can safely used as undefine id.

The layout group determines what actual keyboard layout in the keymap

Both notify::position on the surface actor and position-changed on

It looks that there are some extensions that run a Mainloop on startup,

In such scenario a MetaWindow could try to start a simple effect

Check that if there are multiple modes with the same ID (resolution,

When generating MetaMonitorMode's, prefer CRTC modes that has the same
set of flags as the preferred mode. This not only is probably a better

Under X11 we can only ever have the same scale configured on all
monitors. In order to use e.g. scale 2 when there is a HiDPI monitor
connected, we must not disallow it because there is a monitor that does
not support scale 2. Thus we must show the same scale for every monitor
and monitor mode, even though it might result in a bad experience.
Do this by iterating through all the monitors adding all supported
scales by the preferred mode, combining all the supported scales. This
supported scales list is then used for all monitor and modes no matter

On hybrid GPU systems, hardware cursors needs to be realized on all the
GPUs, as scanout cursor planes cannot be shared. Do this by moving gbm
buffer and drm buffer ID management to a per GPU struct, realizing a
cursor on each GPU when previously only realized on the primary GPU.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
A hybrid GPU system is a system where more than one GPU is connected to
connectors. A common configuration is having a integrated GPU (iGPU)
connected to a laptop panel, and a dedicated GPU (dGPU) connected to
one or more external connector (such as HDMI).
This commit adds support for rendering the compositor stage using the
iGPU, then copying the framebuffer content onto a secondary framebuffer
that will be page flipped on the CRTC of the dGPU.
This can work in two different ways: GPU accelerated using Open GL ES
3, or CPU unaccelerated.
When supported, GPU accelerated copying works by exporting the iGPU
onscreen framebuffer as a DMA-BUF, importing it as a texture on a
separate dGPU EGL context, then using glBlitFramebuffer(), blitting it
onto a framebuffer on the dGPU that can then be page flipped on the dGPU
CRTC.
When GPU acceleration is not available, copying works by creating two
dumb buffers, and each frame glReadPixels() from the iGPU EGL render
context directly into the dumb buffer. The dumb buffer is then page
flipped on the dGPU CRTC.
https://bugzilla.gnome.org/show_bug.cgi?id=785381

In order to eventually support multilpe GPUs with their own connectors,
split out related meta data management (i.e. outputs, CRTCs and CRTC

The Xrandr backend always assumes there is always only a single "GPU" as
the GPU is abstracted by the X server; only the native backend (aside
from the test backend) will eventually see more than one GPU.

order to behave more similarly to the KMS counterparts.

post init backend setup, "setup" the monitor manager state, i.e. read

GTK has the ability to handle client-decorated windows
in such a way that the behavior of these windows must
match the behavior of the current window manager.
In Mutter, windows can be tiled horizontally (and, in
the future, vertically as well), which comes with a few
requirements that the toolkit must supply. Tiled windows
have their borders' behavior changed depending on the
tiled position, and the toolkit must be aware of this
information in order to properly match the window manager
behavior.
In order to provide toolkits with more precise and general
data regarding resizable and constrained edges, this patch
makes MetaWindow track its own edge constraints.
This will later be used by the backends to send information
to the toolkit.
https://bugzilla.gnome.org/show_bug.cgi?id=751857
When computing a potential match for a tiled window, there is a
chance we face the case where 2 windows really complement each
other's tile mode (i.e. left and right) but they have different
sizes, and their borders don't really touch each other.
In that case, the current code would mistakenly assume they're
tile matches, and would resize them with either a hole or an
overlapping area between windows. This is clearly a misbehavior
that is a consequence of the previous assumptions pre-resizable
tiles.
This patch adapts the tile match algorithm to also consider the
touching edges when computing the matching tile, unless:
* the window is not currently tiled (for example when computing
the tile preview)
* the window is currently resized in tandem with an existing
tile match
https://bugzilla.gnome.org/show_bug.cgi?id=645153

When a pair of tiled windows are grouped together, they
are treated as parts of a whole and interacting with one
affects the other.
Following the idea that sibling tiled windows are treated
as part of the same group, they should also be raised and
lowered together.
It is still possible to break tiled windows grouping by
simply untiling the window with the keyboard or by grabbing
and resizing or moving the window with the cursor.
This patch makes sibling tiled windows be lowered and raised
in tandem. For future reference, this behavior is documented
in [1].

There is a variable in meta_window_edge_resistance_for_resize
that isn't really helpful: it just assumes TRUE, and is passed

https://bugzilla.gnome.org/show_bug.cgi?id=645153
When windows are tiled, it improves the interaction with
them when they have a set of snapping edges relative to
the monitor. For example, when there's a document editor
and a PDF file opened, I might want to rescale the former
to 2/3 of the screen and the latter to 1/3.
These snapping sections are not really tied to any other
window, and only depend on the current work area of the
window. Thus, it is not necessary to adapt the current
snapping edge detection algorithm.
This patch adds the necessary code in edge-resistance.c
to special-case tiled windows and allow them to cover
1/4, 1/3 and 1/2 (horizontally) of the screen. These
values are hardcoded.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
After the introduction of the possibility to resize tiled windows,
it is a sensible decision to make windows aware of their tiling
match. A tiling match is another window that is tiled in such a
way that is the complement of the current window.
The newly introduced behavior attepts to make tiling as smooth as
possible, with the following rules:
* Windows now compute their tile match when tiling and, if there's
a match, they automatically complement the sibling's width.
* Resizing a window with a sibling automatically resizes the sibling
too to be the complement of the window's width.
* It is not possible to resize below windows' minimum widths.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
Now that tiled windows are resizable, the user may grow a tiled
windows until it covers the entire work area. As this makes the
window state mostly indistinguishable from maximization, avoid
subtle differences by properly maximizing the window in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
Currently tiled windows are not resizable and their size is fixed
to half the screen width. Adjust the code to work with fractions
other than half, and allow users to adjust the split by dragging
the window edge that is not constrained by a monitor edge.
Follow-up patches will improve on that by resizing neighboring
tiled windows by a shared edge, and making the functionality
available to client-side decorated windows implementing the
new edge constraints protocol.
Now that the preview tile mode has been split from the window's
tile_mode property, it is much more natural to pass the requested
tile_mode to the tile() function instead of setting it externally
and calling the function to apply the state.
The existing semantics of the tile_mode property are terribly confusing,
as it depends on some other property whether it represents the requested
or current mode. Clear this up by just using separate variables for the
two. As it is unlikely that we will ever support more than one tile
preview, we can track the requested mode globally instead of adding

update_num_workspaces() is a no-op when the number of workspaces
did not actually change. That is fine, except that we still want
to initialize the _NET_NUMBER_OF_DESKTOPS hint on startup to not
break components like nautilus-desktop that rely on it.
https://bugzilla.gnome.org/show_bug.cgi?id=760651
Automatic maximization is done when a window is almost the size of the
work area of a monitor. This makes no sense to try when there is no
monitor available, so skip trying to do this when headless.
https://bugzilla.gnome.org/show_bug.cgi?id=787637
When we are headless, treat this as if the window is always not monitor
sized. This might cause windows to temporarly become redirected while
being headless, but this is harmless as when a new monitor is
connected, we'll recalculate weather it should be redirected or not.

Check that configurations where monitors are disabled are properly
used. Also test that old configurations with explicitly disabled

https://bugzilla.gnome.org/show_bug.cgi?id=787629
When saving and restoring monitor configurations, we must take disabled
monitors into account, as otherwise one cannot store/restore a
configuration where one or more monitors are explicitly disabled. Make
this possible by adding a <disabled> element to the <configure> element
which lists the monitors that are explicitly disabled. These ones are
included when generating the configuration key, meaning they'll be
picked up correctly.

When dynamic workspaces are used, we pick up an existing NUMBER_OF_DESKTOP
hint in meta_screen_init_workspaces() to properly restore workspaces
on restart. Unconditionally setting that hint to 1 *before* reading it
breaks that, and we end up shifting all windows to the first workspace.
This reverts commit 8532b10290.

If a non-latin based keyboard layout is active, for example Cyrillic,
keybindings won't work unless we resolve the bound keysyms on a
secondary latin based layout. So, to make keybindings work on non-latin

letters (a-z) and resolve from an additional US layout as well.

The capture_into() function wrote out of bounds when capturing from a
non-origin view (not positioned at (0,0)). At the time of
implementation, this API was used to capture pixels across views into a
single data buffer, but the way it's used, and the way views may work
now, makes this impossible to do properly.
So remove the ability to capture into a pre-allocated buffer from
multiple views, and complain if the passed rectantgle overlapps with
multiple views. This removes the broken offset calculation all
together, fixing the bug motivating this change.
https://bugzilla.gnome.org/show_bug.cgi?id=787715
We currently have a hard coded limit on logical monitor sizes, meant
for filtering out monitor scales that would result in awkward desktop

resolutions that themself are lower than the mentioned limit. To avoid
listing no supported scales, always add the fallback scale 1 if no
other was added.

We cleaned up an unused monitor config list, but what we should do is

We would free the shortcut inhibit data only when the client destroys
its request, which is not the case when the clients itself is
destroyed, leading to a leak of the shortcut inhibit data.
Free the data on resource destruction instead, and simply destroy the
resource on destroy request.
https://bugzilla.gnome.org/show_bug.cgi?id=787568
On Wayland, the grab()/ungrab() in gtk+/gdk are wired to the shortcut
inhibitor mechanism, which in turn shows the dialog, which can take
focus away from the client window when the dialog is shown.
If the client issues an ungrab() when the keyboard focus is lost, we
would hide the dialog, causing the keyboard focus to be returned to the
client surface, which in turn would issue a new grab(), so forth and so
on, causing a continuous show/hide of the shortcut inhibitor dialog.
To avoid this issue, keep the dialog around even if the shortcut inhibit
is canceled by the client, so that the user is forced to make a choice
that we can reuse on the next request without showing the dialog again.
Instead of hiding the dialog when the shortcut inhibitor is destroyed by
the client, we simply mark the request as canceled and do not apply the
user's choice.

Give clients (such as Xwayland) a chance to bind the wl_output global

The foreach CRTC monitor mode helper incorrectly iterated over outputs
without CRTC when non-tiled modes were set on tiled monitors. This was
not expected by callers, so fix the helper to only iterate over active

to check that the disabled outputs mode are set to NULL, so add a
foreach output helper and change the tests to use that instead.

When headless, we don't have any logical monitors to derive a screen

Due to rounding issues, we can't assume a floating point calculation
will end up on an integer, even if we got the factor from the reverse

when they should really be N+1, round the resulting floating point
calculation before casting it to int.
This fixes an issue where using the scale ~1.739 on a 1920x1080 mode

As of commit 5f5ef3de2cdc816dab82cb7eb5d7171bee0ad2c5 in pipewire the

This commit adds basic screen casting and remote desktoping
functionalty. This works by exposing two D-Bus API services:
org.gnome.Mutter.ScreenCast and org.gnome.Mutter.RemoteDesktop.
The remote desktop API is used to create remote desktop sessions. For
each session, a D-Bus object is created, and an application can manage
the session by sending messages to the session object. A remote desktop
session the user to emit input events using the D-Bus methods on the
session object. To get framebuffer content, the application should
create an associated screen cast session.
The screen cast API is used to create screen cast sessions. One can so
far either create stand-alone screen cast sessions, or a screen cast
session associated with a remote desktop session. A remote desktop
associated screen cast session is managed by the remote desktop session.
So far only remote desktop managed screen cast sessions are implemented.
Each screen cast session may have one or more streams. A screen cast
stream is a stream of buffers of some part of the compositor content.
So far API exists for creating streams of monitors and windows, but
only monitor streams are implemented.
When a screen cast session is started, the one PipeWire stream is
created for each screen cast stream created for the session. When this
has happened, a PipeWireStreamAdded signal is emitted on the stream
object, passing a unique identifier. The application may use this
identifier to find the associated stream being advertised by the
PipeWire daemon.
The remote desktop and screen cast functionality must be explicitly be
enabled at ./configure time by passing --enable-remote-desktop to
./configure. Doing this will build both screen cast and remote desktop
support.
To actually enable the screen casting and remote desktop, the user must
enable the experimental feature. See
org.gnome.mutter.experimental-features.

The HW cursor plane can't do any transformations, and as we still don't
pre-transform any buffer before uploading to the cursor plane, we must
disable the HW cursor when a logical monitor is transformed.
This worked previously because the transform of a MetaCrtc did not
correspond to the transform of a CRTC, but the transform of the logical

When resolving what keycodes a key binding resolves to, only look up
key codes from the current layout group. Without this, unwanted
overlaps may occur. For example when a keymap has both a dvorak and a

on multiple keys, arbitrarily "shadowing" another.

When opening a laptop lid, one will likely want to restore the
configuration one had prior to closing it, so when ensuring monitor
configuration, first try to see if the previously set configuration is
both complete (all connected monitors are configured) and applicable
(it is a valid configuration) and only try to generate a new from
scratch if that failed.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
In order to go back in monitor configurations, save them to a history.
The history is implemented as a max 3 element long queue, where newly
set configurations are pushed to the head, and old are popped from the
tail.
The difference between using a single previous config reference and a
queue is that we can now remember the configuration used prior to a
D-Bus triggered configuration when the user discarded the configuration.
This will later be used to restore a previous configuration when a
laptop lid is opened.

So far some basic testing, including:
* Test that the migrated configuration is applicable
* Test that a monitors.xml with multiple configurations are translated
* Test rotation
* Test tiled monitor discovery (well, test a made up tiled monitor
configuration since I don't have a real one)
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This commit changes the new configuration system to use monitors.xml
instead of monitors-experimental.xml. When starting up and the
monitors.xml file is loaded, if a legacy monitors.xml file is
discovered (it has the version number 1), an attempt is made to migrate
the stored configuration onto the new system.
This is done in two steps:
1) Parsing and translation of the old configuration. This works by
parsing file using the mostly the old parser, but then translating the
resulting configuration structs into the new configuration system. As
the legacy configuration system doesn't carry over some state (such as
tiling and scale used), some things are not available. For tiling, the
migration paths makes an attempt to discover tiled monitors by
comparing EDID data, and guessing what the main tile is. Determination
of the scale of a migrated configuration is postponed until the
configuration is actually applied. This works by flagging the
configuration as 'migrated'.
2) Finishing the migration when applying. When a configuration with the
'migrated' flag is retrieved from the configuration store, the final
step of the migration is taken place. This involves calculating the
preferred scale given the mode configured, while making sure this
doesn't result in any overlapping logical monitor regions etc.

The problem is that libinput offers the possibility to not enabled
dragging when tap-to-click is enabled but mutter doesn't. For people who
have a sensitive touchpad and who like tap-to-click option, dragging is
launched even when you don't want it : for example, when you select a
folder, most of the time the folder is dragging whereas just selected or
when you want to select some lines of a text file, several lines are
moved as a cut-paste which is not expected and erase datas.
To fix it, you need to have the possibility to desactivate the drag
option when you use tap-to-click in mutter. Because it's already a
specification of libinput, it remains to add it to mutter.

Since a wl_buffer is independent of the GL context in use (unlike, e.g.,

Moved from g-s-d's media keys plugin, where it was called "video-out",
since it requires changing the current monitor configuration and we
want to remove the old DBus API.
This implementation is intentionally simple and not really meant for
more than debugging and validating the various configurations. A
better user experience will be introduced in gnome-shell with a custom

This will allows us to support the XF86Display key present on some
laptops, directly in mutter. This is also known, in evdev, as
KEY_SWITCHVIDEOMODE.
The common usage for this key is to alternate between a few well known
multi-monitor configurations though these aren't officially
standardized. As an example, Lenovo documents it as:
"Switches the display output location between the computer display
and an external monitor."
On this patch, we're just introducing the configurations that have been
implemented in g-s-d until now, which go a bit beyond the above
description.

Instead of letting MetaMonitor derive the logical monitor size, then
using the main monitor for the position, just let MetaMonitor derive
the whole layout including the position. This means it can deal with
tiled monitors better, for example when the main output (the output
always active when the monitor is active) is not the origin output (the
output with tile position (0, 0)).

We'll need to drop the old monitor configuration system to pave way to
better hi-dpi and multi-gpu support. Let's start by defaulting to the
new system in order to give it more real world testing.
Adds basic support for the "wheel" event from the Wayland tablet protocol.
Ideally we would accumulate the angle and report a wheel event with an
appropriate value for "clicks". We can get away with a much cruder method
for the time being, however, since no Wacom tablet puck actually provides
a smooth scrollwheel. Checking whether the angle in CLUTTER_INPUT_AXIS_WHEEL
exceeds a nominally-small threshold is sufficient to determine that the
wheel has advanced by at least one physical click.

These events will be useful on gnome-shell UI, so translate the

When updating the main monitor, make sure to update the toplevel main
monitor before trying to use that as the main monitor for non-toplevel
windows (such as popups). Without this, when the main monitor is
updated as a side effect to monitors being changed (for example due to
a hot plug event, or coming back from being suspended) the
main monitor pointer may, after 'monitors-changed' has completed, point to
freed memory resulting in undefined behaviour.

The list of files being parsed for enumerations include the header file

Additionally, we are concatenating multiple runs in the same temporary

Since commit 6b5cf2e, we keep override redirect windows on a layer
above regular windows in the clutter actor scene graph. In the X
server, and thus for input purposes, these windows might end up being
stacked below regular windows though, e.g. because a new regular
window is mapped after an OR window.
Fix this disconnect by re-stacking OR windows on top when syncing the
window stack with the compositor.

Differentiate between non-interlaced and interlaced modes. This is done
by appending an "i" after the resolution part of the mode ID, and
adding a 'is-interlaced' (b) property to the mode properties.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
To be more flexible without having to change any D-Bus type signatures
in the future, replace the 'uint' flags value (currently determining
whether a mode is current and/or preferred) with a variant lookup table.
The keys 'is-current' (b) and 'is-preferred' (b) replace the existing
flags.

To be able to add more modes types that happen to have the same

When calculating sizes given some size and a fractional logical monitor
scale with precision loss, round the result of the floating point

To be able to render the pointer cursor sprite at sub-(logical)-pixel
positions, track the pointer position using floats instead of ints.
This also requires users of the cursor sprite rect to deal with

When fractional scaling is used, damage and paint clip region is tracked
in stage coordinate space using integers might end up missing some
pixels when the border ends up on half pixels. Change the damage
tracking and clip regions to be in buffer coordinates so we can align
damage on physical pixel borders.
However, just using rounding up to the next physical pixel results in
glitches. To avoid this, extend the damage by one logical pixel in all
directions, but still (scissor) clip the drawing to the non-extended
region, as otherwise drawing the damaged regions will result in
incorrect pixels on the right and bottom edges of the clip region. It is
possible that there are better ways to do this, which can be explored in
the future.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
We always hit non-fractional floats here because the stage views are
always made so that they are aligned on integer positions with integer

When passing scales over D-Bus, we'll loose some precision. To set the
correct scale, use the configured scale and look up the one actually
supported by the monitor mode, and use that. To match the supported one
with the configured one, the difference must be within rounding error
range.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
We manually scaled pointer motions when they travel over a scaled
monitor. When a stage view of a monitor is also scaled, in practice this

When using logical sized monitors we are allowed to use fractional scaling
but only if the resulting scaled logical monitor size is in integer form.
So, in order to get this, we allow to scale the monitor to up to
8 fractional values per integer, doing some computation in order to
fetch the nearest values which are closer to the scaling factors we can
permit.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
This changes the API to pass supported scales per mode instead of
providing a global list. This allows for more flexible scaling
scenarious, where a scale compatible with one mode can still be made
available even though another mode is incompatible.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When the logical layout mode is used, allow configuring the scaling to
be non-integer. Supported scales are so far hard coded to include at
most 1, 1.5 and 2, and scales that doesn't result in non-fractional
logical monitor sizes are discarded.
Wayland outputs are set to have scale ceil(actual_scale) meaning well
behaving Wayland clients will provide buffers with buffer scale 2, thus
being scaled down to the fractional scale.

When building against a glib-genmarshal from GLib 2.54 we can use the

With GLVND, whenever we have both Mesa's and NVIDIA's drives installed

When the number of (static) workspaces decreases, we relocate windows
from extra workspaces before removing them. As removing a non-empty
workspace is not allowed, we assert that it doesn't contain any windows
before removing it.
However that assert is
- pointless, because meta_workspace_remove() already asserts that
the workspace is empty
- wrong, because even empty workspaces contain windows that are set
to show on all workspaces
Simply drop the assert to avoid a crash when trying to remove a workspace

It is possible to interpret the ammount of padding provided to the
*_set_tablet_area functions in two different and incompatible ways. The X11
backend effectively treats them as being input-centric (i.e., the padding
defines the size of the "dead zone" on the tablet) while the native backend
has an output-centric viewpoint (i.e., the padding defines the size of the
"dead zone" on the display) viewpoint. This difference in opinion causes the
cursor offset to change when switching between Xorg and a Wayland sessions.
The calibration utility within g-c-c does its calculations with an input-
centric viewpoint, so this patch modifies the native backend to work
correctly with these values. To change viewpoints, we can simply invert
the scale and negate the offset. It should be noted that this function
also forgot to apply scaling to the offsets (as required by the matrix
transform done by libinput) which would have further compounded the
cursor offset issue under Wayland.

For size change animations, plugins rely on the size change effect being
followed by size changed signal (or effects being kill altogether).
However unless the move_resize operation included the STATE_CHANGED flag,

A single keysym can resolve to multiple keycodes. Instead of only using
the first one and ignoring the others, we store all codes in
MetaResolvedKeyCombo and then handle all of them in keybinding
resolution. If we already have bound a keycode for a keybinding with a
specific keysym then this can get overwritten by a new keybinding with a
different keysym that resolves to the same keycode. Now that we resolve
and bind all keycodes for a keysym this might happen more often; in that
case warn but still overwrite, but only for the first keycode for each
keysym. If a secondary (i.e. all non-first keycodes) is already indexed
we just ignore that; this should resemble the old behavior where we
only took the first keycode for any keysym as close as possible.

In some circumstances, the origin tile (0, 0) is not the one that

If a client changes the state of a surface to issue a set_maximize, this
causes apply_pending_state() to be called before mutter has placed the
window.
If the monitor on which the window is to be shown initially is different
from the one where the pointer is placed, this causes the effect to be
played at the wrong location before the window eventually reaches its
location on another monitor.
Force the window to be placed prior to change its state to maximized in
xdg-shell so that mutter won't relocate the window afterwards.
This also avoids sending an xdg_toplevel.configure with a size of 0x0

g_hash_table_insert() doesn't replace the key. This was a problem

Make the nested backend emulate how the real backends actually draw,
i.e. by drawing each CRTC separately. This makes it possible to test

Add support for rotated monitors. This is done per logical monitor, as
every monitor assigned to a logical monitor must be transformed in the

offscreen intermediate framebuffer.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Always draw the stage to an offscreen framebuffer when using the nested

Keep track of the logical monitor transform. When a logical monitor is

A logical monitor can either be transformed on the CRTC level, or using

transformed.
MetaCrtcs::transform currently does not represent whether the CRTC is
configured to be transformed or not; only when the backend can handle
it does it correctly correspond to the actual CRTC configuration. This

feature' gsetting keyword "monitor-config-manager" that enables the use
of the new MetaMonitorConfigManager. This commit also makes it possible
to switch between the two systems without restarting mutter.
The D-Bus API is disabled when the experimental feature is not enabled,
and clients trying to access it will get a access-denied error in
response. A new property 'IsExperimentalApiEnabled' is added to let the
D-Bus client know whether it is possible to use the experimental API or
not.

The logical monitor config array ownership was transferred to the
config object when it was created, but was not unset when the config
verification failed, causing the clean up path for invalid configs to
try to clean up the same list again.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This commit adds support for rendering onto enlarged per logical
monitor framebuffers, using the scaled clutter stage views, for HiDPI
enabled logical monitors.
This works by scaling the mode of the monitors in a logical monitors by
the scale, no longer relying on scaling the window actors and window
geometry for making windows have the correct size on HiDPI monitors.
It is disabled by default, as in automatically created configurations
will still use the old mode. This is partly because Xwayland clients
will not yet work good enough to make it feasible.
To enable, add the 'scale-monitor-framebuffer' keyword to the
org.gnome.mutter.experimental-features gsettings array.
It is still possible to specify the mode via the new D-Bus API, which
has been adapted.
The adaptations to the D-Bus API means the caller need to be aware of
how to position logical monitors on the stage grid. This depends on the
'layout-mode' property that is used (see the DisplayConfig D-Bus
documentation).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This gsetting will allow the adding of keywords to a array, where each
keyword may enable an experimental feauter, if the given mutter version
supports that particular experimental feature. Emphasis is put on the
lack of guarantee that any such keyword has any effect. Currently no
keywords are defined.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This commit adds the ability to set a scale on a scale view. This will
cause the content in the stage view to be painted with the given scale,
while still keeping the configured layout on the stage. In effect, for
a stage view with scale 'n', this means the framebuffer of a given stage
will 'n' times larger, keeping the same size on the stage.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Make the concept of maximum screen size optional, as it is not
necessarily a thing on all systems (e.g. when using the native backend
and stage views).
The meta_monitor_monitor_get_limits() function is replaced by a
meta_monitor_manager_get_max_screen_size() which fails when no screen
limit is available. Callers and other users of the previous max screen
size fields are updated to deal with the fact that the limit is
optional.
The new D-Bus API is changed to move it to the properties bag, where
its absence means there is no applicable limit.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a new D-Bus API that uses the state from GetCurrentState to
configure high level monitors, instead of low level CRTCs and
connectors. So far persistent configuration is not implemented, as
writing to the configuration store is still not supported.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Logical monitors in a configuration must be adjecent to each other,
meaning there will be at least one pixel long side touching some other
logical monitor.
The exception to this is when there is only one logical monitor, which
cannot be adjecent to any other.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
We don't want to limit ourself to whole integers for configuration, as
that'd mean it wouldn't be able to provide configurations for
fractional scalings. Thus, change scales to be referred to as floats
instead of ints.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a 'is_underscanning' entry to the properties map, if the monitor
supports underscanning. The client should assume a monitor does not
support underscanning if no property was added.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a D-Bus method for getting the current monitor and logical monitor
state. Currently does not contain information about transforms or any
limitations (such as limited CRTCs and cloning).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Let the backends decide whether to just rebuild a derived state, or use
the NULL config to rebuild an empty logical state.
This also changes the expected screen size values of the no-outputs
test; as this case is actually handled now.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add support to configure the logical monitor scale. With this, it
becomes possible to override the automatically calculated scaling
number per logical monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Replace the 'scale' of an output with a vfunc on the MetaMonitorManager
class that takes a monitor and a monitor mode which calculates the
scale. On X11 this always returns 1, on KMS, the old formula is used.
On the dummy and test backends, the already configured values are
returned.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The default (calculated) scale is derived from the output, but
ultimately set via the monitor scale. This will enable config files to
override the scale. Yet to be done is handling when a scale is not
supported by a backend (i.e. the X11 backend).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
In some cases the hardware cursor is invisible when Mutter is launched from the
TTY, due to drmModeSetCursor2 failing without a fallback being set.
This patch captures the return value of drmModeSetCursor2 and in case of an
error, enables the texture based fallback. It adds a `broken` state, that is
checked in should_have_hw_cursor() and
meta_cursor_renderer_native_realize_cursor_from_*() to avoid copying every
cursor into a gbm buffer when we know it will fail every single time.
https://bugzilla.gnome.org/show_bug.cgi?id=770020
Quick motions can come across as too fast (or slow) if it crosses outputs
with different scales. If this happens, rebuild the motion delta applying
the scale that applies to each logical monitor the pointer is crossing.
https://bugzilla.gnome.org/show_bug.cgi?id=778119
To allow for more natural pointer movements from relative pointer
devices (e.g. mouse, touchpad, tablet tool in relative mode, etc), scale
the relative motion from libinput with the scale of the monitor. In
effect, this means that the pointer movement is twice as fast (physical
movement vs numbers of pixels passed) as before, but it also means that
the same physical movement crosses the distance in a GUI no matter if
it is on a HiDPI monitor or not.
https://bugzilla.gnome.org/show_bug.cgi?id=778119
Clutter's evdev input backend has no support for setting double
click timeout set by gnome-settings-daemon. This results in
touchpad click events timing out on wayland, because the
default timeout value wasn't enough.
This patch moves timeout setting to mutter and removes X11
backend specific setting from clutter.
https://bugzilla.gnome.org/show_bug.cgi?id=771576
The code calculating the output scale involves calculations around pixel
and mm sizes, however we do compare post-transformation pixel sizes to
untransformed mm sizes, which breaks the DPI calculations. Fix this by
transforming back pixel sizes back to untransformed.
While we're at it, actually compare the output height to HIDPI_MIN_HEIGHT
instead of its width, it seems right according to the #define name and
comment.
https://bugzilla.gnome.org/show_bug.cgi?id=777687
When a state changed, e.g. a window went from unfullscreen to
fullscreen, always sync the window geometry, otherwise a compositor
application (e.g. gnome-shell) might end up with an unfinished window
state transition effect.
Without always syncing, the compositor plugin will see a 'size-change'
event, as a result of the state change, but if the size didn't change,
it would never see the 'size-changed' event. If an effect, for example
gnome-shell's fullscreen effect, is triggered on 'size-change' it might
rely on the actual size change to not get stuck. This commit allows it
to have this dependency.
This fixes a bug where a fullscreen effect gets "stuck" when a window
goes fullscreen without changing the window geometry.
https://bugzilla.gnome.org/show_bug.cgi?id=780292
The mitigation to avoid missing EDID blob was incorrect; the reason it
sometimes failed to read was a race between different applications all
trying to read the EDID at the same time. E.g. gnome-shell as GDM would
at the same time as the session gnome-shell try to read the EDID of the
same connector at the same time, triggering a race in the kernel,
making the blob reading ioctl occationally fail with ENOENT.
Remove this mitigation, as it didn't really mitigate anything; the race
could just as well happen when doing the actual read later.
https://bugzilla.gnome.org/show_bug.cgi?id=779837
When mutter is paused (i.e. not the DRM master), stop listening on
hotplug events. Instead read the current state and set modes when
resumed.
This avoids a race condition in the drm API which currently only
manages to properly deal with one application querying the EDID state
at the same time when there are multiple mutter instances running at
the same time (e.g. gnome-shell driving gdm at the same time as
gnome-shell as the session instance).

If the dnd window ends up lower in the overall stack than the window

A MetaOutput is a connector, not exactly a monitor or a region on the
stage; for example tiled monitors are split up into multiple outputs,
and for what is used in input settings, that makes no sense. Change
this to use logical monitors instead of outputs.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
When no output was specified, the screen limit was used to calculate the
aspect ratio. The screen limit, however, is either just an arbitrary
number if no screen limit is applicable, or a hardware graphics buffer
limit, which has nothing to do with anything actually displayed. Change
it to use the screen size instead, to get something that makes more
sense when no output is found.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Expose via a new API whether the transform on a logical monitor is
handled by the backend. This was previously only exposed only in the
native backend. This will be used to emulate not supporting transforms
in the backend in the nested backend.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Previously, the size of the logical monitor was derived directly from
the tiling information. This works fine until we add transformations,
or set modes with a dimension different from the resulting resolution
when tiled. Fix this by traversing the assigned CRTC rects, as these
are already transformed by the configuration system.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
By setting the environment variable MUTTER_DEBUG_TILED_DUMMY_MONITORS
to "1", the dummy MetaMonitorManager backend used when running mutter
nested will create tiled monitors instead of single-output/CRTC
monitors. This makes it possible to test tiled monitor configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Refactor monitor generation by splitting the generation of modes, CRTCs
and outputs into a separate function. A side effect is that each output
will have its own set of possible modes.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
This will be used to invert the transform in the nested mode, making it
possible to test offscreen texture based transform using the nested
backend.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Split up logical monitor cration into derived (when derived from
current underlying configuration) and non-derived (when creating from a
logical monitor configuration). This avoids that type of logic in the
logical monitor creation function.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Add support for non-tiled monitor modes on tiled monitors. This is done
by adding all the other supported modes, except the modes with the
same resolution as the tile dimensions.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
When adding a monitor and all its outputs, don't try to set the logical
monitor of the outputs CRTC if none was assigned. This might happen if
a tiled monitor only uses a subset of the connectors it are connected
via.

Don't set the CRTC rect and screen size at in read_current(), as those

QT apps reject DnD if the timestamp received in the SelectionRequest
event isn't the same it gave in XdndPosition/Drop client messages.
Bookkeeping and using it in XConvertSelection makes it happy again.
https://bugzilla.gnome.org/show_bug.cgi?id=779757
We are keeping accounting of the focus window as seen by the DnD bridge
right here, so use it instead of the MetaWaylandDragGrab focus as it may
lag behind the real focus (i.e. till the drag source notices the window
and sends XdndEnter to it).
This leads to the window trying to be repositioned more often than
necessary when the drag source takes long to send the XdndEnter client
message, and maybe not repositioned at all if the pointer leaves the
surface while no XdndEnter message was received.
https://bugzilla.gnome.org/show_bug.cgi?id=763246
We currently wait for the selection being cleared by the drag source,
which might not happen on not quite educated clients. This may leave
a stuck XDND grab in the compositor side.
We can actually do a bit better, and clear the grab if:
1) The drag source sent XdndDrop to the wayland drag destination.
2) There's no accepting drag destination and all pointer buttons are
released.
3) As usual, whenever the drag source clears the selection data
https://bugzilla.gnome.org/show_bug.cgi?id=763246
We already do have a texture with an internal format in these paths,
so we should check the required format according to it.
This fixes CoglAtlasTexture (and CoglPangoRenderer indirectly), as
it forces a RGBA format on its texture, but pixel_format_to_gl()
anyway assumed swizzling is performed on the texture, while it is
not the case.
https://bugzilla.gnome.org/show_bug.cgi?id=779234
This is used by the GL driver in order to determine whether swizzling
actually applies given the bitmap and target texture internal format.
If both agree that they store BGRA, then swizzling may apply.
https://bugzilla.gnome.org/show_bug.cgi?id=779234
No XDnD events which notify DnD status change comes in Wayland. To emulate XDnD
behavior, MetaDnd checks whether there is a grab or not when the modal window
starts showing. When there is a grab, it processes the raw events from
compositor, and emits DnD signals for plugin.
https://bugzilla.gnome.org/show_bug.cgi?id=765003
Implement MetaDnd for emitting DnD signals to plugins such as gnome-shell. The
xdnd handling code comes from gnome-shell, and it is hidden behind MetaDnd now.

When running nested, the pointer can be outside of the stage, meaning
outside of any logical monitor. Handle this when getting the current

Whenever an EGLOutput consumer is temporary unable to handle
eglStreamConsumerAcquire() operations (e.g. during a VT-switch),
an EGL_RESOURCE_BUSY_EXT error is generated.
This change adds the appropriate error handling to flip_egl_stream() in
order to recover from such errors.
https://bugzilla.gnome.org/show_bug.cgi?id=779112
This change adds descriptions for the following errors to

Ungrabbed pointer motion events over a client window area don't even
reach mutter in X compositor mode, but as a wayland compositor we
process those events which ends up in a call stack like:
- meta_window_handle_ungrabbed_event
- meta_ui_frame_handle_event
- handle_motion_notify_event
- get_control
- meta_ui_frame_calc_geometry
Computing frame geometry is a relatively CPU expensive operation and
doing it on every motion event over a client window is pointless work
since we aren't going to change the cursor or prelight any frame
widget.
This commit special cases the determination of
META_FRAME_CONTROL_CLIENT_AREA using a much faster method. When
continuously moving the pointer over an X (client) window, it results
in a ~40% decrease in mutter cpu usage.
https://bugzilla.gnome.org/show_bug.cgi?id=779436
If the GL implementation/hw supports the GL_*_texture_swizzle extension,
pretend that BGRA textures shall contain RGBA data, and let the flipping
happen when the texture will be used in the rendering pipeline.
This avoids rather expensive format conversions when forcing BGRA buffers
into RGBA textures, which happens rather often with WL_SHM_FORMAT_ARGB8888
buffers (like gtk+ uses) in little-endian machines.
In intel/mesa/wayland, the performance improvement is rather noticeable,
CPU% as seen by top decreases from 45-50% to 25-30% when running
gtk+/tests/scrolling-performance with a cairo renderer.
https://bugzilla.gnome.org/show_bug.cgi?id=779234
Set up things so that if the INTEL_swap_event extension is not present,
but the driver is known to have good thread support, we use an extra
thread and call glXWaitVideoSync() in the thread. This allows idles
to work properly, even when Mutter is constantly redrawing new frames;
otherwise, without INTEL_swap_event, we'll just block in glXSwapBuffers().
https://bugzilla.gnome.org/show_bug.cgi?id=779039
Because the threaded-swap-wait functionality requires XInitThreads(),
and because it isn't clear that it is a win for all applications,
add a API function to conditionally enable it.
Fix the cogl-crate example not to just have a hard-coded dependency
on libX11.
https://bugzilla.gnome.org/show_bug.cgi?id=779039
It's a good guess that the buffer swap will occur at the next vblank,
so use glXWaitVideoSync in a separate thread to deliver a sync event
rather than just letting the client block when frame drawing, which
can signficantly change app logic as compared to the INTEL_swap_event
case.
https://bugzilla.gnome.org/show_bug.cgi?id=779039
When we don't have GLX_OML_sync_control, we still can set the
frame presentation time, but we always use the system monotonic time,
so return that from get_clock_time().

As previously commented in the code, SGI_video_sync is per-display, rather
than per-renderer. The is_direct flag for the renderer was tested before
it was initialized (per-display) and that resulted in SGI_video_sync
never being used.

Commits 6dbec6f8, 734402e1 and f041b35b introduced memory leaks by
switching to returning copies instead of the original buffers but
forgetting to free those original buffers.
Some error cases were also not freeing the ->prop buffer as they
should.
https://bugzilla.gnome.org/show_bug.cgi?id=642652
Wayland windows can be zero sized until clients attach a buffer, but
our rectangle code doesn't deal with this case well, in particular,
meta_screen_get_monitor_for_rect() might end up choosing the wrong
monitor for a zero sized rectangle since
meta_rectangle_contains_rect() considers a zero sized rectangle at the
right or bottom edges of another rectangle (the monitor's) to be
contained there.
Since out size limits constraint will enforce a minimum size of 1x1,
we might as well enforce that when setting up the constraint info so
that the correct monitor gets chosen and the single monitor constraint
doesn't move these windows to the wrong one.
https://bugzilla.gnome.org/show_bug.cgi?id=772525
Wayland windows are initially zero sized until clients commit the
first buffer. Despite being invisible, clients are allowed to request
such windows to be fullscreened on a specific output before they
attach the first buffer which means we need to be able to move them.
meta_window_move_to_monitor() doesn't handle this case because these
windows' initial monitor is a placeholder since their initial
coordinates are 0,0+0+0, which results in us using a rectangle as
old_area for meta_window_move_between_rects() that might be to the "right"
of the window causing the move to go further out of the visible
screen's coordinates. This is later "corrected" by the constraints
system but the window might end up in the wrong monitor.
To fix this, we can make meta_window_move_between_rects() accept a
NULL old_area, meaning that we move the window to the new_area without
trying to keep a relative position.
https://bugzilla.gnome.org/show_bug.cgi?id=772525
The reason for the display to be closed may be meta_screen_new()
returning NULL, in which case we don't have a screen to free.

We currently don't have any shadow class for combo box popups,
which means the default shadow of normal windows is used. That's
clearly odd given that the two are very different, and isn't
consistent with GTK+-3's client-side shadows for popups. While
we could add a dedicated shadow class, the designers are fine
with reusing the existing shadow for dropdown-menus, so let's
do that.

Split up the X11 backend into two parts, one for running as a
Compositing Manager, and one for running as a nested Wayland

This commit also cleans up the compositor configuration calculation,

https://bugzilla.gnome.org/show_bug.cgi?id=777800
In order to minimize the amount of breakage, while at the same time
making it easier to make backward incompatible changes needed to
continue turning libmutter into a capable Wayland compositor, make the
libmutter and friends (libmutter-clutter, libmutter-cogl*) parallel
installable by adding a version number to the name. This changes
various filenames, for example what previously was libmutter.so is now
libmutter-0.so (assuming the version for now is 0), and
libmutter-clutter-1.0.so is now libmutter-clutter-0.so. The pkg-config
filenames and GObject introspection has been renamed to reflect this as
well.
This enables a downstream compositor rely on a specific version of the
libmutter API, while gracefully handling API/ABI changes by having to
update to the new version at their own pace.

We couldn't properly merge output-mapping matrix and calibration into

When != 0, this property will express the W:H ratio of the desired
output area (be it one monitor or the span of all monitors). At
the time of translating coordinates, coordinates will be skewed so
that the input area of the tablet is a rectangle of the given ratio.
Events happening in the input areas that fall outside the output
aspect ratio will be clamped to the nearest coordinate in the rect.
If the ratio is 0, the whole input area of the tablet will be used
and no coordinate skewing will happen.
https://bugzilla.gnome.org/show_bug.cgi?id=774115
And transform absolute events using this matrix. This property is
akin to the "Coordinate Transformation Matrix" property in X11,
and will be used to map tablets/touchscreens to outputs, favoured
over the libinput matrix which is meant for calibration.

If the meta_window_actor_effect_completed() triggers inconsistent

unexpected at this time too, which will lead to a g_error().

times than necessary in the upper parts. A warning will be issued,
but the process won't abort.

Since both the libinput event source and the key repeat timer have the
same priority, the order in which both handlers are called is
arbitrary if both sources are ready on the same poll return. This
means that sometimes we generate key repeats when there's already a
real key event queued on libinput that would cancel the repeat timer
if only it was processed before.
One solution would be lowering the repeat timer source priority a
notch lower than the libinput source but that would mean that a steady
stream of events from libinput (e.g. pointer device motion) would
prevent any key repeats to happen.
Instead, we can fix this problem by trying to dispatch libinput from
the key repeat timer and checking if the timer source has been
destroyed before generating more key repeats.

The MetaOutput::is_primary state was not correctly managed in two cases:
* for tiled monitors, the primary state got overridden when setting
the preferred resolution
* for laptop lid, it was not set if the laptop panel happened to be
the first output
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The main output of the main (first) monitor of a primary logical
monitor should have the MetaOutput::is_primary field set; all other
outputs should have it not set.
All outputs associated with a logical monitor with presentation set
should have MetaOutput::is_presentation set. No other outputs should
have it set.

Add a flag to the test setup creation function enabling the caller to

MetaMonitorConfigStore provides an XML storage mechanism for
MetaMonitorConfigManager. It stores configuration files defined in the

Only reading custom files are implemented and so far unused.

The new monitor configuration system (MetaMonitorConfigManager) aims to
replace the current MetaMonitorConfig. The main difference between the
two is that MetaMonitorConfigManager works with higher level input
(MetaMonitor, MetaMonitorMode) instead of directly looking at the CRTC
and connector state. It still produces CRTC and connector configuration
later applied by the respective backends.
Other difference the new system aims to introduce is that the
configuration system doesn't manipulate the monitor manager state; that
responsibility is left for the monitor manager to handle (it only
manages configuration and creates CRTC/connector assignments, it
doesn't apply anything).
The new configuration system allows backends to not rely on deriving the
current configuration from the CRTC/connector state, as this may no longer be
possible (i.e. when using KMS and multiple framebuffers).
The MetaMonitorConfigManager system is so far disabled by default, as
it does not yet have all the features of the old system, but eventually
it will replace MetaMonitorConfig which will at that point be removed.
This will make it possible to remove old hacks introduced due to
limitations in the old system.

Sometimes we hit a race on hot-plug where we try to read the KMS

The function meta_monitor_manager_read_current_config() was renamed to

A monitor spec object is meant to be used to identify a certain monitor
on a certain output. The spec is unique per actual monitor and connector,
meaning that a monitor that changes from one connector from another

to associate for example a configuration entry with an actual monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a "mode spec" concept, meaning to be used as a identifier for an

https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add "monitor modes" abstracting the modes set on a monitor. On normal

Don't deal with adding/removing tiled Xrandr monitors in the generic

MetaLogicalMonitor. This means that mirrored tiled monitors will now be
represented correctly.

Put the monitor xinerama index in a separate struct that is attached to

Don't store logical monitor specific state in an array where the index

Instead of storing the logical monitors in an array and having users
either look up them in the array given an index or iterate using

To complement the current API which takes an index referencing a

A window manager must select the SubstructureRedirect mask on the root
window to receive the MapRequest from the X11 clients and manage the
windows. Without this event mask set, a window manager won't be able to
map any new window.
The Wayland selection code in mutter can change/clear the event mask on
the requestor window from a XSelectionRequest event when the window is
not managed by mutter/gnome-shell.
A rogue or simply buggy X11 client may send a XConvertSelection() on the
root window and mutter will happily change/clear its own event mask on
the root window, effectively turning itself into a regular X11 client
unable to map any new X11 window from the other X11 clients.
To avoid this, simply check that the requestor window is not the root
window prior to change/clear the event mask on that window.

Commit 5eb5f72 - wayland: Check surface outputs after mapped state

Commit 4295fdb892 made us skip focusing
all xdg_popups instead of just non-grabbing ones as intended. This
means that when unmanaging a window we might select a xdg_popup window
to focus (in meta_stack_get_default_focus_window() ) but then since we
don't actually focus it we go on unmanaging the focused window which
triggers an assertion, as it should.
To avoid this and still fixing bug 771694 we can make use of the
MetaWindow->input property for non-grabbing xdg_popup windows since
their semantics, in this regard, are the same as no input X11 windows.
This way, when unmanaging a focused window while a xdg_popup is up,
we'll either give focus to the xdg_popup or not select the popup at
all to be focused if it's non-grabbing.

We need to do swap notifications asynchronously from flip events since
these might be processed during swap buffers if we are waiting for the
previous frame's flip to continue with the current.
This means that we might have more than one swap notification queued
to be delivered when the idle handler runs. In that case we must
deliver all notifications for which we've already seen a flip event.
Failing to do so means that if a new frame, that only swaps buffers on
such a swap notification backlogged Onscreen, is started, when later
we get its flip event, we'd notify only an old frame which would hit
this MetaStageNative's frame_cb() early exit:
if (global_frame_counter <= presented_frame_counter)
return;
and we'd never finish the new frame and thus clutter's master clock
would be waiting forever stuck.

When flush-swap-notify is already queued, we might end up trying to

A window's unconstrained_rect is essentially just the target rectangle
we hand to meta_window_move_resize_internal() except it's not updated
until the window actually moves or resizes.
As such, for wayland client resizes, since they're async, using
window->unconstrained_rect right after calling move_resize_internal()
to update the grab anchor position on unmaximize doesn't work as it
does for X clients.
To fix this, we can just use the target rectangle for the grab
anchor. Note that comment here was already wrong since it says we
should be taking constraints into account and yet the code used the
unconstrained rect anyway.

This reverts commit 989ec7fc60.
We now rely on accurately knowing if a window moved and/or resized in

In order for the compositor plugin to be able to animate window size
changes properly we need to let it know of the starting and final
window sizes.
For X clients this can be done synchronously and thus with a single
call into the compositor plugin since it's us (the window manager)
who's in charge of the final window size.
Wayland clients though, have the final say over their window size
since it's determined from the client allocated buffer.
This patch moves the meta_compositor_size_change_window() calls before
move_resize_internal() which lets the compositor plugin know the old
window size and freezes the MetaWindowActor.
Then we get rid of the META_MOVE_RESIZE_DONT_SYNC_COMPOSITOR flag
since it's not needed anymore as the window actor is frozen and that
means we can use meta_compositor_sync_window_geometry() as the point
where we inform the compositor plugin of the final window size.
https://bugzilla.gnome.org/show_bug.cgi?id=770345
This will be used to let plugins know when a previous size change
actually becomes effective. This is needed to handle wayland client
resizing properly since, unlike X, it's async.

Normally textures in OpenGL are inverted on the Y axis, and we only

https://bugzilla.gnome.org/show_bug.cgi?id=773629
This commit adds for a new type of buffer being attached to a Wayland
surface: buffers from an EGLStream. These buffers behave very
differently from regular Wayland buffers; instead of each buffer
reperesenting an actual frame, the same buffer is attached over and
over again, and EGL API is used to switch the content of the OpenGL
texture associated with the buffer attached. It more or less
side-tracks the Wayland buffer handling.
It is implemented by creating a MetaWaylandEglStream object, dealing
with the EGLStream state. The lifetime of the MetaWaylandEglStream is
tied to the texture object (CoglTexture), which is referenced-counted
and owned by both the actors and the MetaWaylandBuffer.
When the buffer is reattached and committed, the EGLStream is triggered
to switch the content of the associated texture to the new content.
This means that one cannot keep old texture content around without
copying, so any feature relying on that will effectively be broken.
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Add API to enable the caller to have a custom method for allocating an
external texture. This will enable the possibility for mutter to
generate a texture from for example an EGLStream without having to add

https://bugzilla.gnome.org/show_bug.cgi?id=773629
Add support for inverted Y Wayland buffers. OpenGL textures are by
default inverted, so adding support for EGL_WAYLAND_Y_INVERTED_WL
effectively means adding support for non-inverted, which makes the
MetaShapedTexture apply a transformation when drawing only when querying
EGL_WAYLAND_Y_INVERTED_WL resulted in the response "EGL_FALSE".
https://bugzilla.gnome.org/show_bug.cgi?id=773629
Don't rely on the Cogl layer having Wayland specific paths by
determining the buffer type and creating the EGLImage ourself, while
using the newly exposed CoglTexture from EGLImage API. This changes the
API used by MetaWaylandSurface to make the MetaWaylandBuffer API be
aware when the buffer is being attached. For SHM and EGL buffers, only
the first time it is attached will result in a new texture being
allocated, but later for EGLStream's, more logic on every attach is
needed.

This commit adds support for using a EGLDevice and EGLStreams for
rendering on top of KMS instead of gbm. It is disabled by default; to

There is no way to pass any backend specific parameters to a
CoglFramebuffer until after it has been allocated by
cogl_framebuffer_allocate() (since this is where the winsys/platform
fields are initialized). This can make it hard to actually allocate
anything, if the platform depends on some backend specific data.
A proper solution would be to refactor the onscreens and framebuffers to
use a GObject based type system instead of the home baked Cogl one, but
that'll be left for another day. For now, allocate in two steps, one to
allocate the backend specific parts (MetaOnscreenNative), and one to
allocate the actual onscreen framebuffer (via
meta_onscreen_native_allocate()).
So far there is nothing that forces this separation, but in the future
there will, for example EGLDevice's need to know about the CRTC in
order to create the EGLSurface.

Similarly to Weston (where this code originated), there were two errors
in the X11 lockfile handling.
Firstly, after reading 11 characters from the lock file (which could
have been placed by any process), there was no guarantee of
NUL-termination, meaning strtol could've theoretically run off the end
of the string.
Secondly, whilst writing the new lock, the trailing NUL byte was not
correctly accounted for. The size passed as an input to snprintf takes
the maximum size of the string including the trailing NUL, whilst the
return (and the input to write) gives the actual size of the string
without the trailing NUL.
The code did attempt to check the return value, however snprintf returns
the size of the _potential_ string written, before snprintf culls it, so
this was off by one, and the LF was not being written.

Some applications like Wine may choose to juggle the same user time
window across different toplevels, in that case we receive warnings
when trying to register the window a second time, leading to wrong
accounting.
If the window was already used as the user time window for another
toplevel, unset it from the previous MetaWindow owner, and unregister
so the registration with the new MetaWindow is successful.

This is implemented using Wacom-driver specific properties at
the moment, until libinput becomes the fallback driver handling
tablet and pad management.
Whenever a tool becomes in proximity, a new ClutterInputDeviceToolXI2
will be created (if it wasn't created previously) for the given
serial number. This tool will be set in all events send from the
device.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
The Clutter X11 backend can't drop CLUTTER_PEN_DEVICE and
CLUTTER_ERASER_DEVICE in favor of CLUTTER_TABLET_DEVICE without
losing information (as the driver will create one device for each).
So make MetaInputSettings cater for both sets of device types.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
Its only purpose was caching settings applying to an stylus/tool, this
is now handled through ClutterInputDeviceTool evdev specific API, or
X device properties, so is not needed anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
Stylus configuration (stylus buttons, pressure) was handled
at the very high level, doing the button and pressure translations
right before sending these to wayland clients.
However, it makes more sense to store these settings into the
ClutterInputDeviceTool itself, and have clutter apply the config
at the lower level so 1) the settings actually apply desktop-wide,
not just in clients and 2) X11 and wayland may share similar
configuration paths. The settings are now just applied whenever
the tool enters proximity, in reaction to
ClutterDeviceManager::tool-changed.
This commit moves all handling of these two settings to
the clutter level, and removes the wayland-specific paths
https://bugzilla.gnome.org/show_bug.cgi?id=773779
We do so whenever a tool enters or leaves proximity. We now also
ensure that last_tool is NULL after it leaves proximity, although
the CLUTTER_PROXIMITY_OUT event itself should still contain tool
information.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
And remove the wayland-specific handling. This works for both Wayland and
X11 (provided the compositor receives pad events through a passive grab
there).
https://bugzilla.gnome.org/show_bug.cgi?id=773779
We most notably handle button events (acquired through a passive grab on
all device buttons) which are translated to CLUTTER_PAD_BUTTON* events,
so there is generic handling of pad actions on X11.
https://bugzilla.gnome.org/show_bug.cgi?id=773779
We kind of rely on the ::show-pad-osd handler to destroy the
previous actor. Just prevent the emission of multiple signals
till the actor has been destroyed.

Wayland popup grabs, unlike other grab types, can be safely cancelled
so there's no reason to deny compositor grab requests if a wayland
popup is on.
In particular, this allows entering the overview via a keybinding or
locking the screen while a wayland popup has a grab which is something
that's been advertised as a wayland improvement over X.

Enabling edge scrolling before disabling two finger would result in
edge scrolling not actually being enabled because two finger is still
enabled at the time and we bail out.
This patch moves this logic to common code for both the native and X
backends and fixes it by ensuring that both settings are never set at
the same time and still re-checking if edge scrolling should be
enabled after two finger scrolling gets disabled.
We also simplify the code by not checking for supported/available
settings since the underlying devices will just reject those values
and there isn't anything we can do about it here. It's the UI's job to
only show supported/available settings to users.
https://bugzilla.gnome.org/show_bug.cgi?id=771744
Checking for supported methods isn't needed since libinput will just
error out and do nothing itself if a requested method isn't supported

Commit fcc7501eb8 had the side-effect of
stacking fullscreen windows below docks which went unnoticed since we
don't use docks in GNOME anymore.
Instead of re-introducing the fullscreen layer, which we don't need
otherwise, we can fix this issue by ensuring we stack docks below all
other windows when the monitor they're on is marked fullscreen. This
has the added benefit that the visibility rule for 3rd party docks
becomes the same as gnome-shell's chrome.

The keyboard focus semantics for non-grabbing xdg_shell v6 popups is
pretty undefined.
Same applies for subsurfaces, but in practice, subsurfaces never receive
keyboard focus, so it makes sense to do the same for non-grabbing
popups.
https://bugzilla.gnome.org/show_bug.cgi?id=773210
mutter would remove focus from a toplevel when showing one of its
transient window which is not on top and not focused.
When using xdg_popup without grab as allowed in xdg_shell v6, the popup
wouldn't be focused, and if an intermediate event occurs before the
popup is shown, it's not placed on top either, which could randomly
trigger a loss of focus in the corresponding toplevel window.
Remove that special case, it doesn't make much sense to globally unset
focus when mapping a new window.

commit e2bfaf0751 does this:
g_hash_table_insert (cards,
g_udev_device_get_name (parent_device),

g_udev_device_get_name call leading to a crash.
This commit does the get_name call on an earlier line
https://bugzilla.gnome.org/show_bug.cgi?id=771442
Right now we accept any character device that matches the glob card*.
That's fine, but we can be a little more specific by checking that

We shouldn't cancel the pointer grab when there is a compositor grab,
since that'd break things like drag-n-drop via the overview and
alt-tabs.
The original reason for cancelling the pointer grab on compositor grabs
was to avoid a re-entry when a compositor grab was activated while
there was an active pointer constraint grab. The re-entry would happen
when the compositor grab cleared the pointer focus. Clearing the focus
would trigger the pointer constraint to be deactivated, which would end
its grab. Ending the grab would reset the grab to the default one, which
could focus the same surface again, triggering the constraint to
re-enable before it finished disabling.
This is now avoided because the default grab handler is now aware of
compositor grabs, and won't override the cleared pointer focus until
the compositor grab ends.
https://bugzilla.gnome.org/show_bug.cgi?id=772914
Teach the default grab about compositor grabs (i.e.
display->event_route) so that it can avoid setting a pointer focus when
after the compositor grab actively unset the pointer focus.
https://bugzilla.gnome.org/show_bug.cgi?id=772914
The frame rect will at this point not be set for Wayland popups, since
the popup is placed and constrained before the actual buffer will be
attached. To still be able to calculate a proper monitor to be used for
constraining, use the ConstraintInfo::current dimensions instead, since
they will have the expected size. This should not cause any issues with
present paths since when a window is otherwise placed, it usually
doesn't change monitor calculation result.
This fixes opening a popup menu that would be positioned on the left
edge of a not-left-most monitor, for example a 'File' menu on a window
maximized on a second monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=773141
Using the view's MetaMonitorInfo to find all the crtcs which should be
configured to display a given onscreen doesn't work unfortunately. The
association runs only the other way around, i.e. we need to go through
each crtc and find the ones corresponding to our monitor info.
https://bugzilla.gnome.org/show_bug.cgi?id=773115
If this isn't initialized and an idle watch gets instanced before
meta_idle_monitor_native_reset_idletime() gets called, that idle watch
would get triggered as soon as we hit the main loop.
This was causing gnome-session to go into idle mode at session start
thus making gnome-shell lock the screen.
In the past this bug was being masked by either logind emiting
session active signals or a stray input event making it through at
startup.

Commit 5fbb479301 was wrong too. What we

When disabling the device/capability, we can't rely on cancelled events
being emitted timely, because the capability will be already disabled by

When the monitor is scaled (i.e. HiDPI scaling) the placement coordinates
ere still in unscaled xdg_surface window geometry coordinate space when
used to place the window. Fix this by scaling the coordinates by the
monitor scale of the parent toplevel window before using them.
https://bugzilla.gnome.org/show_bug.cgi?id=771841
Always use the monitor of the toplevel surface's window, so that the
popup menu and the parent will always have the same scale. This fixes
the dimensions sent in the xdg_popup configure event.
https://bugzilla.gnome.org/show_bug.cgi?id=771841
When Xwayland confines, the surface dimensions will include the server
side window manager decorations. We don't want the decorations to be
included in the constraint region so intersect the calculated input
region with the parts of the buffer rect that is not part of the window
frame.
https://bugzilla.gnome.org/show_bug.cgi?id=771859
Put the conditions for enabling a pointer constraint in a helper
function, and use that in both maybe_enable() and maybe_remove(). The
constraint region checking is still only done in maybe_enable()
however.
This changes the conditions for maybe disabling the constraint on focus
change and other trigger points, namely it makes constraints by Xwayland
not disable when they shouldn't due to the constraining window being an
override-redirect window.
https://bugzilla.gnome.org/show_bug.cgi?id=771859
When the grab is cancelled, for example because of an Alt-tab, VT
switch etc, disable or remove (depending on the constraint type) the
constraint. This avoids a re-entry issue when the focus is returned and
the focus listener tries to re-enable a disabled constraint.
https://bugzilla.gnome.org/show_bug.cgi?id=771859
Dismiss the popup when the grab is cancelled, so that if the grab is
ended for whatever reason (such as VT switching or the last pointer
being disconnected), it doesn't try to end the grab when it isn't
active.
This fixes a crash when VT switching back and forth while a popup grab
is active.
https://bugzilla.gnome.org/show_bug.cgi?id=771858
Previously a grab could suddenly end without the grabber knowing
anything about it. Some grabs assume they won't suddenly end without
notice, and can use then new 'cancel' vfunc to be notified.
Currently a grab is cancelled when a new one is started (i.e. in
meta_wayland_pointer_grab_start()), when a non-popup compositor wide
event route is initiated, and when the seat looses the pointer
capability.
https://bugzilla.gnome.org/show_bug.cgi?id=771858
Instead of using meta_wayland_pointer_end_grab() which focuses the new
grab, add a new helper mean to be used to reset the grab state without
changing the pointer focus. When using this function, the call site is
supposed to explicitly manage focus.
https://bugzilla.gnome.org/show_bug.cgi?id=771646
Make the caller of focus setting check whether there is a pointer to
update the focus state of. It makes it more obvious what to expect, as
the call would be a no-op in when no pointer is present.
Grabbing is still allowed without the presence of a pointer because it
is used by popups even on touch-only systems.
https://bugzilla.gnome.org/show_bug.cgi?id=771646
Make the caller of focus setting and grab starting check whether there
is a keyboard to update the focus state or start grabbing. It makes it

GNOME Shell's window matching currently fails frequently with Flatpak
applications, as one of the primary hints used to link windows with
.desktop files - the WM_CLASS - no longer matches when flatpak renames
the exported .desktop file. Luckily, Flatpak provides us with a fail-safe
way to map from the PID to the corresponding application ID, so expose an
appropriate method that allows GNOME Shell to reliably match windows to
the corresponding Flatpak app.
https://bugzilla.gnome.org/show_bug.cgi?id=772614
In order to kill a window, on both X11 and wayland we first try to
kill(3) the corresponding process, so we can add the newly added
get_client_pid() method to share that code.
https://bugzilla.gnome.org/show_bug.cgi?id=772613
It is often useful to identify the client process that created
a particular window, however the existing meta_window_get_pid()
method relies on _NET_WM_PID, which is only available on X11 and
depends on applications to set it correctly (which may not even
be possible when the app runs in its own PID namespace as Flatpak
apps do). So add a get_client_pid() method that uses windowing
system facilities to resolve the PID associated with a particular
window.

Previously the focus was reset implicitly by a memset() on the whole
MetaWaylandPointer struct. When MetaWaylandPointer was turned into a

Going through the global mode pool and then checking if the mode is
available for a given output is pointless work since we can look at
the output's available modes directly.
This implicitly changes how we choose the default mode since, instead
of relying on the sort order of the global modes array, we now rely on
the sort order of the output modes array. Still not ideal, but at
least it makes more sense since the global array is essentially
unsorted.
https://bugzilla.gnome.org/show_bug.cgi?id=772176
This isn't technically needed and, in fact, makes us default to

As the m format specifier doesn't consume any arguments, the number

instead of removing the excess argument.
There may be other windows managing selection whose events are seen in
our GDK event filter, like st-clipboard in gnome-shell, we should in
that case not interfere on Selection/SelectionRequest events that are
not meant for us.
This fixes an odd feedback loop where requesting clipboard contents from
wayland results in a XConvertRequest call and a SelectionRequest event
that is interpreted by mutter as a request from another X11 client, so
the current data source is poked for content, which happens to be the
X11 bridge, which does a XConvertRequest to get contents... This is only
broken after the many nested async operations create enough pipes and
cancellables to run out of fds.
Adding checks to ensure only events meant to our "selection owner"
window are managed prevent this unintended loop to happen in the first
place.

A xdg_popup, when active, always has a parent surface. However, a popup
created may immediately become invalid, for example when it is not
granted a grab, in which case it won't be assigned a parent since it
will never be mapped.
This case needs to be handled elsewhere, as one cannot assume a
MetaWaylandXdgPoup that is processed (via wl_surface commit handling
etc) will have a parent_surface.

If a X11 client would initiate a Xdnd session after it had lost pointer
focus (for example when the Xdnd event starting the drag happens after
the implicit pointer grab is already broken due to the button being
released), just end the drag operation instead of dereferencing the
non-existing focus surface.
Also avoid using a native Wayland surface as a drag origin, as that can
never happen, but allow any arbitrary Xwayland client, since there is
no way to find out the actual drag origin.
https://bugzilla.gnome.org/show_bug.cgi?id=770940
We cannot check 'has-target' or 'has-seat' when verifying a
wl_data_offer.finish request is valid or not, since the source may have
effected 'has-target' or whether theh source has a seat or not when the
finish request was already on the wire.
Instead of checking against the source state, keep track whether the
required operations has been done on the offer in question (i.e.
whether an action has been sent, or a mime type been accepted).
This fixes incorrectly raised error when dragging from gtk+'s testdnd
via Xwayland onto gtk+'s testdnd using Wayland.

Now with the existance of offscreen view framebuffers the buffer age
damage regions are only valid if the view in question doesn't doesn't

Also maybe remove a constraint when the pointer focus changes. This is
needed because when Xwayland has a constraint focus may change, the
constraint object will not receive a 'appears-focused' event on its
window since it never changed.
This happens for example when an override-redirect window (which never
appears focused) holds the constraint, and alt-tab happens. In this case
focus changes, but from the constraint's point of view, none of the
windows it knows about changed its focus appearance.
https://bugzilla.gnome.org/show_bug.cgi?id=771345
Instead of initializing the default grab when the device class is
enabled, initialize it on object initialization. This way other device
classes can still grab the pointer, as if there was one. This may be
useful for example if a touch grab is active and a mouse is connected.
This also makes it possible for popup grabs, which currently use a
pointer grab for controlling, to be triggered by touch devices, while
still holding an active pointer grab.

Since Xwayland surface constraints might need to enable not only
because the constrained window appears focused, add a pointer focus
listener and try constrain whenever the pointer focus changes. It's
still required that a Xwayland window is focused to activate.
https://bugzilla.gnome.org/show_bug.cgi?id=771050
Xwayland surfaces are special, because there is no reliable way to
associate a window with its corresponding "application window" (the one
which was given focus). Many games that require pointer warping and
confining pointer grabs may for example create override redirect windows
and make that window receive input even though it will never be the
focus window.
Therefore, the requirements for enabling a constraint for a wl_surface
from Xwayland needs to be relaxed in order. This commit changes
Xwayland wl_surfaces to not require being focused to be enabled; it'll
be enabled as long as any X11 window is the one with focus.

Clutter discards any motion event if next event happens to also be a

If a client would attach a buffer to a surface, commit, destroy the

by logging a warning and treating a prematurely destroyd wl_buffer as if

Not having a surface actor would cause the window actor state to be
considered frozen, thus causing various state (such as geometry, shape
etc) synchronization to be delayed until thawed. If the window actor
was "thawed" due to having a surface set, not all state would be
properly synchronized, causing the thawed window actor to be displayed
incorrectly.
This patch fixes this by putting state synchronization after thawing in
a common function, calling it both from frozen count decreasing and
surface setting.
This fixes for example misplaced menus in Steam.

The seat capability updating is synchronous, but input events are
asynchronous (first queued then emitted). This means we may end up in a
situation where we from libinput first may receive a key event,
immediately followed by a device-removed event. Clutter will first
queue the key event, then remove the device, immediately triggering the
seat capability removal.
Later, when the clutter stage processes the queued events, the
previously queued key event will be processed, eventually making it
into MetaWaylandSeat. Before this patch, MetaWaylandSeat would still
forward the key event to MetaWaylandKeyboard, even though it had
'released' it. Doing this would cause referencing potentially freed
memory, such as the xkb state that was unreferenced when the seat
removed the capability.
In order to avoid processing these lingering events, for now, just drop
them on the floor if the capability has been removed.
Eventually, the event queuing etc needs to be redesigned to work better
when used in a Wayland compositor, but for now at least don't access
freed memory.

When a modal transient is unmanaging, most likely the parent of the
modal transient should be focused.
In Wayland, a MetaWindow is created when a shell surface role (like
xdg_toplevel) is created, but a window cannot be shown until a buffer
is attached. If a client would create two modal transients and make
them both have the same parent, but only one get a buffer attached
(i.e. shown), when unmanaging the modal transient that was showing,
when finding a new focus candidate, the stacking code will ignore the
not-to-be-shown buffer-less modal transient when finding a good
candidate for focusing. In the case described here, this means it will
find the parent of the unmanaging modal transient.
This newly chosen candidate will then be passed to meta_window_focus();
meta_window_focus() will then try to find any modal transient to focus
instead, will find the one without any buffer, then fail to focus it
because it cannot be mapped, thus making meta_window_focus() not focus
anything. Since meta_window_focus() didn't change any focus state, the
assert in meta_window_unmanage() checking that the unmanaging window
isn't focused anymore will be hit, causing mutter to abort.
For now, fix this by checking whether the modal transient can actually
be focused in meta_window_focus(). For X11 client windows, a window
will be defined to be focusable always, but for Wayland client windows,
a window will be determined focusable only if it has a buffer attached.
In the future, we should probably do a more thorough refactorization of
focus handling to get rid of any X11 - Wayland differences.

We may be assigned multiple times, if the surface is assigned to be a
cursor surface multiple times. Each time e.g. wl_pointer.set_cursor is
called, we'll be assigned.
While the role object exists, we'll handle buffer use count even when
we are not actively assigned, thus we should only handle the initial
assignment use count bump when constructing, so that we don't increase
it when reassigned, where the wl_resource may already have been
released.

For backend handled cursors, if nothing else changes on the clutter
stage, we end up not sending out frame callbacks since clutter doesn't
draw a new frame.
To fix this, we'll keep cursor surfaces' frame callbacks separate from
other surfaces' and trigger them from the new
MetaCursorRenderer::cursor-painted signal which handles both software
and hardware cursors.
https://bugzilla.gnome.org/show_bug.cgi?id=749913
This signal allows interested parties to be notified of a new cursor
frame being painted regardless of whether it's being painted by the
backend directly or if it's a software rendered cursor frame handled
by clutter.

Even without a compositor grab, key events may still be expected to
be processed by the compositor and not applications, for instance
when using ctrl-alt-tab to keynav in the top bar. On X11, focus is
moved to the stage window in that case, so that events are processed
before they are dispatched by the window manager. On wayland, we need
to handle this case ourselves, so make sure to not pass key events to
wayland in that case, and move the key focus back to the stage when
appropriate.

If cogl fails to create a texture from the client's given buffer,

For some reason, when a modal dialog was made an attaching
transient-for, if the window wasn't "constructing", it would be
unmanaged and rely on some side effect to be recreated. This side
effect is not triggered for Wayland clients, thus if one happen to set
a surface as "modal" via gtk_surface.set_modal before
xdg_toplevel.set_parent, it'd be unmanaged and never show up.
Instead, simply just set the tranciency anyway for Wayland clients.
This makes GTK+ clients that set_modal() before set_transient_for()
work.

Windows from Xwayland still needs to use the Wayland path, but is

This reverts commit 9fb891d216.

There is nothing stopping a subsurface from commiting its state before
its parents role has been assigned. Thus, we need to handle
meta_wayland_surface_get_toplevel() returning NULL for subsurfaces even
on commit.
Make sure to always call the parent role commit vfunc, so that they can
handle updating their state properly.
This means other places need to handle the situation where
surface->window is NULL on commit. This may for example happen when the
parent of a modal dialog is unmapped or NULL is attached to a

We can only honor this properly in the MUTTER_STAGE_VIEWS=1 case. When using

The offscreen is given through the ::back-buffer property, the ClutterStageView

framebuffer.
The pipeline can be altered through the setup_pipeline() vfunc, so ClutterStageView
implementations can alter the default behavior of blitting from offscreen to
onscreen with no transformations.

been updated to call the right clutter_stage_view_get_onscreen() function.

Those will need a separate treatment from the modes that we eventually

Also, add a helper function that returns the transform that the software

already handled via hw.
The function applying the configuration has been modified to always set
a HW rotation mode (even if normal), when we come to support SW rotation
modes, we'll be relying on a normal transformation, so it will be
necessary to have mixed HW/SW managed transforms.

If the compiler cannot figure out that the condition for setting
the dev variable is the same as the condition for accessing it,
it will complain about potential uninitialized use.
We must lookup the mode switch serial for the group where the button
belongs to. Also, avoid the changes if the client requests setting
the feedback for buttons owned by the compositor.
We assumed that each group could only have 1 strip and/or ring, because
accounting is performed per group, so we could not assume the real
index for anything above 1. Get rid of this restriction, now that
MetaWaylandTabletPad does its own accounting of rings/strips, alongside
groups.
This is best for 2 reasons:
- It's feels cleaner doing first creation of rings/strips and then
the group assignment. The other option is making groups iterate
other all rings/strips and selectively skip those not meant for
it, which sounds somewhat redundant.
- Some minimal accounting of rings/strips without group restrictions
is needed for meta_wayland_tablet_pad_get_label().
The rings/strips memory is now owned by MetaWaylandTabletPad instead
of groups, which is sort of meaningless since all are meant to go
at the same time.
There may be external/compositor-specific reasons to trigger the
pad OSD. Expose this call so the pad OSD can be triggered looking
up the right settings, monitor, etc...
This API will be used from the gnome-shell pad OSD implementation, in order
to show the actions that currently apply to every button/ring/strip in the
tablet.
It does nothing at the moment, but can be hooked into MetaWaylandTabletPad
now. For X11, we need to trigger these for the pad events we receive from
the passive pad button grabs.
This function will be useful for the wayland implementation, because buttons
are mapped at the time of sending those through the wire.
As x11/wayland implementations differ here, this function will be useful for
the wayland implementation, as the action is handled lat
Some settings make no sense on external tablets, and others make
no sense in display/system-integrated tablets. Perform those checks
so we don't end up with possibly broken configuration.
Depending on clutter_input_device_get_mapping(), or whether the current
tool is either cursor or lens (those don't make any sense in absolute
mode), relative motions will be reported.
This function call only applies to tablets, and thus will error
out unless it's called with CLUTTER_TABLET_DEVICEs. This will
allow setting absolute/relative mapping on those on the fly, as
this is optional.
Given that information defines largely how such devices are to be
configured, it makes sense to have that information at hand. A getter
has been also added for the places where it could be useful, although
it will require HAVE_LIBWACOM checks in callers too.
All pads will share the same focus than the keyboard, so this means that:
- The focus changes in-sync for keyboard and all pad devices, and
- Newly plugged pads will be immediately focused on that same surface
This object represents the collection of buttons, strips and rings
in a tablet pad. All the objects created (pad, strips and rings)
share a common focus surface and have the same lifetime.
This will only be practical for pads (and maybe generic buttonsets in
the future?), we just need to know the number as the events will also
contain a number as the identificator.
Those map closely what we get from libinput. Button events have
been made its own separate struct, its semantics fall somewhere
in between of ClutterButtonEvent and ClutterKeyEvent, so is better
emitted as its own set.
This is now separated from the generic cursor one. This means that wl_surfaces
can't be shared across wl_pointer and wp_tablet_tool. This is a change in
tablet protocol v2.
This is a simple subclass of MetaWaylandSurfaceRoleCursor, mostly
so we can distinguish by GType, the methods in the parent class
still apply and are useful.
When launching a GNOME session from a text-mode VT, the logind session
type is unlikely to be set to either "wayland" or "x11". We search for a
supported session type first with logind and then with
$XDG_SESSION_TYPE. As a fallback, we also test $DISPLAY in case of a
"tty" logind session to support starting through xinit. Ideally, such
setups should set XDG_SESSION_TYPE=x11.
If no supported session type is found, we throw an error.

Just like in GDK though, we need to keep the old definition for

By creating a pending gbm/EGL surface pair, only setting it on

This was in the past not very noticable since some non-deterministic but

Add support for drawing a stage using multiple framebuffers each making
up one part of the stage. This works by the stage backend
(ClutterStageWindow) providing a list of views which will be for
splitting up the stage in different regions.
A view layout, for now, is a set of rectangles. The stage window (i.e.
stage "backend" will use this information when drawing a frame, using
one framebuffer for each view. The scene graph is adapted to explictly
take a view when painting the stage. It will use this view, its
assigned framebuffer and layout to offset and clip the drawing
accordingly.
This effectively removes any notion of "stage framebuffer", since each
stage now may consist of multiple framebuffers. Therefore, API
involving this has been deprecated and made no-ops; namely
clutter_stage_ensure_context(). Callers are now assumed to either
always use a framebuffer reference explicitly, or push/pop the
framebuffer of a given view where the code has not yet changed to use
the explicit-buffer-using cogl API.
Currently only the nested X11 backend supports this mode fully, and the
per view framebuffers are all offscreen. Upon frame completion, it'll
blit each view's framebuffer onto the onscreen framebuffer before
swapping.
Other backends (X11 CM and native/KMS) are adapted to manage a
full-stage view. The X11 CM backend will continue to use this method,
while the native/KMS backend will be adopted to use multiple view
drawing.

https://bugzilla.gnome.org/show_bug.cgi?id=768976
If you include a file that might define __INSIDE_COGL_H__, don't
undefine it if it wasn't defined in that file. This makes it possible
to include for example cogl-gles2.h from some other file which defines
__INSIDE_COGL_H__.

Introduce two new clutter backends: MetaClutterBackendX11 and
MetaClutterBackendNative. They are so far only wrap ClutterBackendX11
and ClutterBackendEglNative respectively, but the aim is to move things
from the original clutter backends when needed.
https://bugzilla.gnome.org/show_bug.cgi?id=768976
Using clutter API to transform coordinates is only accurate right
after a clutter layout pass but this function is used e.g. to deliver
pointer motion events which can happen at any time. This isn't a
problem for wayland clients since they don't control their position,
but X clients do and we'd be sending outdated coordinates if a client
is moving a window in response to motion events.
https://bugzilla.gnome.org/show_bug.cgi?id=768039
This layer isn't really being used and in fact, it causes
meta_stack_get_default_focus_window() to return a fullscreen window
even if the naturally topmost window in the stack isn't a fullscreen
one.
Note that commit a3bf9b01aa changed how
we choose the default focus window from the MRU to the topmost in the
stack.
https://bugzilla.gnome.org/show_bug.cgi?id=768221
Since the check for backend->cogl_context was accidentally moved
to clutter_backend_do_real_create_context, the Glib source that
is created at the end of clutter_backend_do_create_context() is
created and added each time create_context() is called, though
create_context() is supposed to be idempotent.
https://bugzilla.gnome.org/show_bug.cgi?id=768243
When restarting (X compositor only, obviously), we want to keep
the same window focused. There is code that tries to do this by
calling XGetInputFocus() but the previously focused window will
almost certainly not still be focused by the time we get to the
point where we call XGetInputFocus(), and in fact, probably was
no longer correct after the previous window manager exited, so
the net result is that we tend to focus no window on restart.
A better approach is to leave the _NET_ACTIVE_WINDOW property
set on the root window during exit, and if we find it set when
starting, use that to initialize focus.
https://bugzilla.gnome.org/show_bug.cgi?id=766243
Emit a signal so that interested parties can recreate their FBOs and
queue a full scene graph redraw to ensure we don't end up showing
graphical artifacts.
This relies on the GL driver supporting the
NV_robustness_video_memory_purge extension and cogl creating a
suitable GL context. For now we only make use of it with the X backend
since the only driver with which this is useful is NVIDIA.
https://bugzilla.gnome.org/show_bug.cgi?id=739178
When using a context with robustness, glGetError() may return
GL_CONTEXT_LOST at any time and this error doesn't get cleared until
the application calls glGetGraphicsResetStatus() . This means that our
error checking can't call glGetError() in a loop without checking for
that return value and returning in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=739178
The call fetching the targets mistakenly used the timestamp meant
to back up the TIMESTAMP atom (hence, it's the timestamp at which
the selection is *owned* by the compositor, on behalf of a wayland
client).
This timestamp is actually only updated when the compositor gets
to own the selection, so it's a randomly late timestamp to retrieve
the TARGETS atom content, which certain clients might end up
ignoring.
https://bugzilla.gnome.org/show_bug.cgi?id=768007
Frames are painted on the frame window according to the GTK+ theme.
Depending on the target's visual, this means either drawing over
a black destination or a fully transparent one. So in cases where
the theme doesn't paint decorations with full opacity, decorations
for windows with an rgba visual look different from those with a
non-rgba visual. Using an rgba visual for all frames independent
from the client's visual can potentially break clients, so our
only option for a consistent appearance is to explicitly initialize
the frame background to black before painting the theme's decoration
on top.
https://bugzilla.gnome.org/show_bug.cgi?id=745060
The GTK+ theme may draw parts of the decorations outside the actual
frame. Since commit f9db65f47f we make sure that the frame is big
enough to account for any overdrawing, however as we still clip the
cairo context to the actual frame before drawing the decorations,
those parts aren't actually painted.
This issue is not very obvious for most frames, as they use a non-rgba
visual where the unpainted parts appear black, which gives the expected
result with many themes once the shape mask is applied (as the mask does
include any overdrawn parts). For frames using an rgba visual however,
unpainted parts are transparent, so any overdrawn decorations are clearly
missing.
Fix this by only clipping out the client area when drawing decorations.
https://bugzilla.gnome.org/show_bug.cgi?id=745060
We ignore all damage while a surface is frozen and queue a full
update instead once it's thawed. While not super efficient, this
isn't overly bad for the intended case of catching up with any
updates that happened during a compositor effect. However when
extended frame sync is used, surfaces are also frozen while the
client is drawing a frame, in which case the current behavior is
pretty damaging (pun intended), as we end up redrawing the entire
window each frame. To address this, keep track of the actual damage
we ignore and apply it when the surface is thawed.
https://bugzilla.gnome.org/show_bug.cgi?id=767798
The result flag needs to be marked as moved even for pending moves,
otherwise the window's unconstrained_rect doesn't get updated in
meta_window_move_resize_internal() and the anchor grab is wrong.
https://bugzilla.gnome.org/show_bug.cgi?id=764180
The X11 backend uses EWMH's _NET_WM_PID to get the PID of an offending
client and kill its PID to force the client to terminate.
The Wayland backend is using a Wayland protocol error, but if the client
is hung, that will not be sufficient to kill the client.
Retrieve the client PID under Wayland using the Wayland client API
wl_client_get_credentials() and kill() the client the same way the X11
backend does.

xdg-shell allows desktop environments to extend the list of states
within a given range.
Use this possibility to add a new state for tiled so that gtk+ can
benefit from this.
https://bugzilla.gnome.org/show_bug.cgi?id=766860
gjs throws exceptions on non UTF-8 strings which, in some cases, crash
gnome-shell. ICCCM string properties are defined to be Latin-1 encoded
so we can try to convert them to avoid it.
Note that _NET_WM_NAME is defined to be UTF-8 and we already validate
it in utf8_string_from_results() .
https://bugzilla.gnome.org/show_bug.cgi?id=752788
printf string precision counts bytes so we may end up creating invalid
UTF-8 strings here. Instead, use glib's unicode aware methods to clip
the title.
https://bugzilla.gnome.org/show_bug.cgi?id=765535
This makes us behave the same both on bind and when an output
changes. In particular, we were not sending scale and done events on
output changes. We were also unconditionally sending mode events on
output changes even though these should only be sent if there is an
actual mode change.
https://bugzilla.gnome.org/show_bug.cgi?id=766528
Stacking hidden X windows below the guard window is a necessity to
ensure input events aren't delivered to them. Wayland windows don't
need this because the decision to send them input events is done by us
looking at the clutter scene graph.
But, since we don't stack hidden wayland windows along with their X
siblings we lose their relative stack positions while hidden. As
there's no ill side effect to re-stacking hidden wayland windows below
the X guard window we can fix this by just doing it regardless of
window type.
https://bugzilla.gnome.org/show_bug.cgi?id=764844
If we try to send notify event (either from surface_state_changed()
or from meta_window_wayland_move_resize_internal()),
we will crash, because we don't have a sufrace anymore.
There's no reason why to resize the window that is being
unmanaged anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=751847
meta_parse_accelerator() considers 0 length accelerator strings as
valid, meaning that the keybinding should be disabled. Unfortunately,
it doesn't initialize the MetaKeyCombo so if the caller doesn't
initialize it either, we end up using random values and possibly
grabbing random keys.
https://bugzilla.gnome.org/show_bug.cgi?id=766270
The 'select-all' action is currently only bound to <ctrl>a, which makes
it awkward to use when caps-lock is active, and is inconsistent with GTK+.
Just accept both upper- and lower-case variants.
https://bugzilla.gnome.org/show_bug.cgi?id=766326
All the upper layers are prepared for multiple onscreen cursors, but
this. All MetaCursorRenderers created would poke the same internal
MetaOverlay in the stage.
This will lead to multiple cursor renderers resorting to the "SW"
rendering paths (as it can be seen with tablet support) to reuse the
same overlay, thus leading to flickering when a different
MetaCursorRenderer takes over the overlay.
Fix this by allowing per-cursor-renderer overlays, their lifetime
is attached to the cursor renderer, so is expected to be tear down
if the relevant device (eg. tablet) disappears.
meta_wayland_tablet_manager_update()/handle_event() are called before
the MetaWaylandSeat counterparts. If the event comes from a device
managed by MetaWaylandTabletManager, the event will be exclusively handled
by it.
Each tool has its own MetaCursorRenderer instance, which is created/destroyed
upon proximity, and possibly updated through focus and set_cursor calls in
between.
This struct keeps the server side information for the wl_tablet_manager
global resource. It keeps the clients requesting this interface, and
does keep track of the plugged tablet devices, so
wl_tablet_manager.device_added is emitted on the expected clients.
Move into a standalone meta-wayland-surface-role-cursor.[ch], and
make generic enough to work for pointe and additional (eg. tablet)
cursors.
Most notably, the sprite is now kept completely internal to the
cursor role, and updates are routed through the given
MetaCursorRenderer (which may be the default one for the pointer,
or something else).
The way cursor updates after cursor surface destruction has also
been reworked, the pointer will just keep track of the last cursor
surface, so older surfaces being destroyed don't trigger pointer
rechecks/updates.
There's places where it would be convenient to add listeners to this,
so add the signal. The signal is only emitted once during destruction,
it is convenient for the places where we want notifications at a time
the object is still alive, as opposed to weak refs which notify after
the fact.
The device name is something more natural, similar to what's seen
in X11, the sysname is rather the event node basename, which may
also vary depending on device insertion/detection time.
Sadly, GLib's autoptr cleanup macros cannot be detected by the C
pre-processor, because they generate a function. This means that we are
forced to bump up the dependency on GLib 2.49, in order to build against
a newer version of gdbus-codegen.
Starting from GLib 2.49, the gdbus-codegen tool automatically generates
the auto cleanup symbols for the GDBus proxy and skeleton interfaces.
Since we don't depend on a specific version of GLib we need to
conditionally generate the auto cleanup symbols in case an older version
of gdbus-codegen is used when building Mutter.
This commit unbreaks the build under GNOME Continuous, which has been
failing with:

Separate "xdg_surface", "xdg_popup" and "xdg_shell" related functions
into three sections. Prior to this, the "xdg_shell" part was a bit all
over the place.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Dismiss the popup when the parent is destroyed, and do this in the
destructor of the parent object. This makes the parent destory listener
unnecessary, since we already handle the parent child unlinking
explicitly in the object destructor.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Instead of relying on destroy signals attached to the corresponding
role object, let the roles explicitly dismiss the popup when it should
be dismissed.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Add a bridge between the MetaWaylandPopup object and the corresponding
popup surface role. This bridge replaces communicating dismissed and
unmapped popup events.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
The only time the surface pointer (priv->surface) may be NULL is when
the surface is unmanaged but still painting, possibly due to a unmap
animation or the like, so only guard handle this situation in the entry
points that may come from the stage painting.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Before this commit, on Wayland, the buffer rect would have the size of
the attached Wayland buffer, no matter the scale. The scale would then
be applied ad-hoc by callers when a sane rectangle was needed. This
commit changes buffer_rect to rather represent the surface rect (i.e.
what is drawn on the stage, including client side shadow). The users of
buffer_rect will no longer need to scale the buffer_rect themself to
get a usable rectangle.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
A large part of meta_wayland_surface_apply_window_state() was only
relevant for xdg_surface. Make this more obvious by splitting it up,
moving the relevant parts to the relevant roles.
https://bugzilla.gnome.org/show_bug.cgi?id=763431
Move xdg_shell related functionality to a new meta-wayland-xdg-shell.c
and wl_shell related functionality to a new meta-wayland-wl-shell.c,
and adapt role object tree.
Common functionality related to the surface being drawn as a
MetaSurfaceActor was moved to a MetaWaylandSurfaceRoleActorSurface role.
The subsurface role GObject is made to inherit the actor surface GObject.
Shell surface hooks (configure, ping, close, popup done) were added to
a MetaWaylandSurfaceRoleShellSurface GObject which inherits the
surface actor role GObject.
The shell surface roles (xdg_surface, xdg_popup, wl_shell_surface) are
made to inherit the shell surface GObject and implement the relevant
API.
