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
another per-window variable.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=787637
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.

We currently have a hard coded limit on logical monitor sizes, meant
for filtering out monitor scales that would result in awkward desktop

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

This avoids updating state (such as position, size etc) when going

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

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
calculation. Thus, to avoid casting away values like N.999... to N,
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
resulted in error when setting the mode, as the calculated size of the
framebuffer was only 1919x1080.

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.

When monitors changed, previous monitor instances are defunct, and any

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
monitor the CRTC was assigned to.

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
qwerty layout on different layout groups, one keybinding may be bound
on multiple keys, arbitrarily "shadowing" another.
https://bugzilla.gnome.org/show_bug.cgi?id=786408
Add API to get the layout group (layout index) currently active. In the

Don't wait for clutter to initialize for connecting to X11; do it when

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.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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.
Implementation with X11 is added too.

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

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

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)).

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.

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.

Additionally, we are concatenating multiple runs in the same temporary

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
calculation to the closest integer, as otherwise we might end up with
result smaller by 1 if there was a loss of precision when calculating
the scale.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
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
floating points, when e.g. finding the logical monitor etc.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
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
meant we scaled twice. Avoid this by only manually scaling the pointer
motion when stage views are not scaled.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
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.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
To support fractional scaling, change the stage view scale to be a
float instead of an int. Also change the places where it is retrieved
and used when scaling things.

Previously gnome-shell listened on the Xft Xsettings via GTK+s

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
while on-all-workspaces windows are present.

Wacom's display tablets typically do not have (0,0) coincident with the top

While it doesn't make sense to set a window as transient to

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,
the size changed event emitted when the compositor syncs the window

To avoid animations getting stuck in that case, make sure to include the
flag when tiling a window.

Use the "destroy" MetaWaylandSurface signal instead of the wl_resource

As unsetting the focus may have side effects due to handlers of the

the surface destruction before we try to unset the focus.

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.

We will both create and destroy monitors during initialization (when

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

MetaMonitorTiled to support this case. It also seems to be so that the

both tiles.

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

If the client doesn't set a geometry using xdg_shell, we'll compute its

g_hash_table_insert() doesn't replace the key. This was a problem
because the key was owned by the value inserted into the hash table, so
when a value was removed, the key was freed, meaning that the key in
the hash table was no pointing to freed memory. Fix this by using
g_hash_table_replace() instead, which work the same except that it
replaces the key with the one passed. This means that the key of a
value in the hash table is always the key owned by the value.

This adds a function to be used by gnome-shell to get the logical

Make the nested backend emulate how the real backends actually draw,
i.e. by drawing each CRTC separately. This makes it possible to test
different configuration paths that can take place on different
hardware, without having said hardware.
For example, by setting MUTTER_DEBUG_TILED_DUMMY_MONITORS and
MUTTER_DEBUG_NESTED_OFFSCREEN_TRANSFORM to "1", one can test a system
with MST (tiled) monitors where the GPU doesn't support some transform.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add the transform as a logical monitor parameter, both when getting the
current state and applying a new configuration. The transform is defined

Adds a <transform> element to <logicalmonitor>. It has two possible sub

https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add support for rotated monitors. This is done per logical monitor, as
every monitor assigned to a logical monitor must be transformed in the
same way. This includes being transformed on the same level; e.g. if
the backend does not support transforming any monitor of a logical
monitor natively, then all monitors will be transformed using 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
backend, so that we more emulate things more similarly to how it works
real-world, i.e. it'll work the way whether stage views are enabled or
not.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The CRTC position depends on the transform and how the transform is
implemented. The function calculating the positions still doesn't
support anything but the non-transformed case; this commit is in

https://bugzilla.gnome.org/show_bug.cgi?id=777732
Keep track of the logical monitor transform. When a logical monitor is
transformed, all of its monitors are also transformed in the same way.
A logical monitor can either be transformed on the CRTC level, or using
an offscreen intermediate buffer. In both cases will the logical
monitor be transformed, but only in the latter will the view be
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
is intended to change with MetaMonitorConfigManager.

The D-Bus API is disabled when the experimental feature is not enabled,

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
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

Logical monitors in a configuration must be adjecent to each other,

Replace the 'scale' of an output with a vfunc on the MetaMonitorManager
class that takes a monitor and a monitor mode which calculates the

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

In some cases the hardware cursor is invisible when Mutter is launched from the

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.

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.

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
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

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
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

Whenever an EGLOutput consumer is temporary unable to handle

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
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().

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()

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,
attempting to make it more approachable.
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.

This signal provides the necessary information to let gnome-shell trigger

And add specific private methods to notify about tablet mapping and mode

Function "handle_raise_or_lower (src/core/keybindings.c)" is called
when running 'raise-or-lower' on a window. This function iterates

If the meta_window_actor_effect_completed() triggers inconsistent
accounting, there's also high chances that the thaw call will be
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.

Make sure that each logical monitor owns the expected actual monitors.
This currently needs special care when dealing with laptop lid the

https://bugzilla.gnome.org/show_bug.cgi?id=777732
This is partly redundant given that the current monitor mode is checked
against the CRTC mode, but this also checks the disabled CRTCs. Later

The main output of the main (first) monitor of a primary logical

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

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.
