Some output devices only advertise their preferred mode even though
they're able to display others too. This means we can include some
common modes in each output's supported list.
This is particularly important for mirroring, since we can only mirror
outputs which are using the same resolution.

Instead of hiding stage views enablement behind MUTTER_STAGE_VIEWS=1,

Switch to the output naming logic used by the X server's modesetting
driver which, in particular, uses drmModeConnector's connector_type_id
instead of connector_id.
The kernel generates new connector_id's every time there are changes
which means we can't identify the same monitor on the same connector
after an hardware hotplug. Switching to connector_type_id fixes this.
https://bugzilla.gnome.org/show_bug.cgi?id=770338
We can only honor this properly in the MUTTER_STAGE_VIEWS=1 case. When using
the legacy view, software implemented transforms are only exposed if there is
only one output, as we can only transform the entire stage there.
https://bugzilla.gnome.org/show_bug.cgi?id=745079
The texture is only created if the view is transformed at the software level,
otherwise the texture is NULL, and rendering happens on the onscreen.

The offscreen is given through the ::back-buffer property, the ClutterStageView
will set up the the CoglPipeline used to render it back to the "onscreen"
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.
All getters of "the framebuffer" that were expecting to get an onscreen have
been updated to call the right clutter_stage_view_get_onscreen() function.
https://bugzilla.gnome.org/show_bug.cgi?id=745079
The call to _cogl_framebuffer_winsys_update_size() results in no-op here,
as the framebuffer has already the right size when rebuilding the views.

Those will need a separate treatment from the modes that we eventually
support through "software", so split those into a separate enum so we
can can do the right thing when applying the configuration.
Also, add a helper function that returns the transform that the software
fallbacks should perform, which should be "normal" if the rotation is
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.

As whether edge scrolling is enabled depends on whether two-finger
scrolling is disabled, make sure to update two-finger scrolling first.
Note that this only fixes the problem on startup. Changing the
settings in GSettings directly might cause an inconsistent state, but
the main UI for this setting, gnome-control-center, makes sure to
update two-finger scrolling before edge scrolling.

Support changing the mouse and trackball acceleration profile. This
makes it possible to for example disable pointer acceleration by
choosing the 'flat' profile.
This adds an optional dependency on gudev. Gudev is used by the X11
backend to detect whether a device is a mouse or not. Without gudev
support, the accel profile settings has have effect for mouse devices.
Trackball still uses the "strstr" approach, since udev doesn't support
tagging devices as trackball devices yet.

Add support for setting edge-scrolling separately from two-finger
scrolling. We now have 2 separate boolean settings for those, with the
Mouse panel in gnome-control-center allowing to set only one of those at

We need to handle:
- two-finger-scrolling-enabled and edge-scrolling-enabled settings both
being set.
- those 2 settings being change out-of-order
- two-finger-scrolling being set on a device that doesn't support it
- edge-scrolling-enabled on a device that doesn't support it
And the combinations of one touchpad supporting just one of edge
scrolling and two-finger scrolling and another vice-versa.

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.
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.
They are already effectively interchangeable so this should reduce
pointless casts.
Just like in GDK though, we need to keep the old definition for
instrospection to be able to include the struct's fields.
By creating a pending gbm/EGL surface pair, only setting it on
swap-buffers, we would draw onto a buffer on the old surface, then swap
the buffer from the new surface, causing the first frame after a
hot-plug always having no content.
This was in the past not very noticable since some non-deterministic but
frequent side effect in gnome-shell caused hot-plugging to always render
two new frames, but after "Introduce regional stage rendering", this
side effect did not occur as often, thus making it more visible.
This commit updates the current gbm/EGL surface pair before painting a
frame, so that when the frame is painted, the surface with the correct
size is used and the buffer from correct surface is swapped.

Being a listener to a signal, it is inconvenient to enforce order of

CoglFrameInfo is a frame info container associated with a single
onscreen framebuffer. The clutter stage will eventually support drawing
a stage frame with multiple onscreen framebuffers, thus needs its own
frame info container.
This patch introduces a new stage signal 'presented' and a accompaning
ClutterFrameInfo and adapts the stage windows and past onscreen frame
callbacks users to use the signal and new info container.

Call a CoglContext "cogl_context", CoglDisplay "cogl_display" and

Make the cogl vfunc functions have names that are globally
discoverable. Calling the same function in every backend the same name
causes code navigation tools to not function properly. Rename the

https://bugzilla.gnome.org/show_bug.cgi?id=768976
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
In preperation for having allowing drawing onto multiple onscreen
framebuffers, move the onscreen framebuffer handling to the
corresponding winsys dependent backends.
Currently the onscreen framebuffer is still accessed, but, as can seen
by the usage of "legacy" in the accessor name, it should be considered
the legacy method. Eventually only the X11 Compositing Manager backend
will make use of the legacy single onscreen framebuffer API.
https://bugzilla.gnome.org/show_bug.cgi?id=768976
Split the stage window implementations into three separate objects: one
for X11 as a compositing manager, one for X11 running as a nested
Wayland compositor, and one for running with the native backend.
The new stage window implementations are only thin shells; this is in
preparation for making the stage windows behave more differently.

This commit completes the move of monitor logic to the monitor

Let MetaMonitorManagerKms manage KMS modes. This lets us pass less

Move the KMS interaction from cogl into mutter, where most of the other
KMS interaction already takes place. This also removes dead code which
were only excercised when non-mutter callers used the cogl KMS backend.
The cogl KMS API was updated to pass via MetaRendererNative instead of
via the different cogl objects.

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

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.

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.
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

While CoglError is a define to GError, it doesn't follow the convention
of ignoring errors when NULL is passed, but rather treats the error as

That's clearly unwanted for a compositor, so make sure to always pass

that is not a malformed blend string).

The previous configuration might not apply because the number of
enabled outputs when trying to apply it might have changed. This isn't

with.

On the X11 backend we don't track the pointer position in
priv->current_x/y which remain set to zero. That means we never set
the clutter stage cursor if point 0,0 isn't covered by any monitor
since we return early.
Commit 4bebc5e5fa introduced this to
avoid crashing on the prepare-at handlers when the cursor position
doesn't fall inside any monitor area but we can handle that higher up
in the stack. In that case, the sprite's scale doesn't matter since
the cursor won't be shown anyway so we can skip setting it.

It indirectly triggers expensive operations in gnome-shell
(js/ui/keyboard.js), which turns out too expensive if we happen to operate
the shell simultaneously with 2 devices that will trigger the operations
there.
So just rate limit the signal emission, defer to an idle and just emit
the last device gotten. Worst that will happen is that we may possibly
emit the signal on the same device consecutively.

The wp_pointer_constraints protocol is a protocol which enables clients
to manipulate the behavior of the pointer cursor associated with a seat.
Currently available constraints are locking the pointer to a static
position, and confining the pointer to a given region.
Currently locking is fully implemented, and confining is implemented for
rectangular confinement regions.
What else is lacking is less troublesome semantics for enabling the lock
or confinement; currently the only requirement implemented is that the
window that appears focused is the one that may aquire the lock.
This means that a pointer could be 'stolen' by creating a new window that
receives active focus, or when using focus-follows-mouse, a pointer
passes a window that has requested a lock. This semantics can be changed
and the protocol itself allows any semantics as seems fit.
https://bugzilla.gnome.org/show_bug.cgi?id=744104
In order to reuse some vector math for pointer confinement, move out

This fixes an issue analogous to bug 760330 for the X11 backend,
except on this backend we wouldn't crash accessing free'd memory.
Instead we're leaking watches since we steal them from the hash table
which means that when they're removed in
_meta_idle_monitor_watch_fire() they're no longer there and thus
they're never free'd.
https://bugzilla.gnome.org/show_bug.cgi?id=760476
Right now the XSync based idle monitoring code, will fetch all active
watches into a list, and then call their watch callbacks one by one
as necessary. If one watch callback invalidates another watch, the
list will contain free'd memory.
This commit makes sure to consult the hash table after ever call
of a watch callback, to ensure mutter never looks at freed memory.

We can know the rotation modes supported by the driver, so
export these as our supported modes, and ensure these modes
are honored on the CRTC primary plane upon apply_configuration().
It is worth noting however that not all hardware will be
capable of supporting all rotation modes (in fact, most of
them won't). A driver independent solution should be in
place to back up the rotation modes unsupported by the
drivers, so this is still a partial solution.
The cursor renderer has also been changed to default to
software-based rendering anytime the cursor enters a
rotated CRTC. Another solution would be actually rotating
the DRM cursor planes, but then it requires applying rotation on
these per-CRTC, and actually transforming the pointer position by
the output matrix. This brings marginal gains, so we use the
"sw" rendered cursor, which will be transformed together with
the primary plane.

The max potential number of logical monitors (i.e. MetaMonitorInfos)
is the number of CRTCs, not the number of outputs.
In cases where we have more enabled CRTCs than connected outputs we

re-allocated rendering invalid some MetaCRTC->logical_monitor pointers
assigned previously and thus ending in crashes later on.

On the wire, Wayland specifies the refresh rate in milliHz. Mutter sends
the refresh rate in Hz, which confuses clients, e.g. weston-info:
interface: 'wl_output', version: 2, name: 4
mode:
width: 2560 px, height: 1440 px, refresh: 0 Hz,
flags: current preferred
interface: 'wl_output', version: 2, name: 5
mode:
width: 3200 px, height: 1800 px, refresh: 0 Hz,
flags: current preferred
and xrandr:
XWAYLAND0 connected 2560x1440+3200+0 600mm x 340mm
2560x1440@0.1Hz 0.05*+
XWAYLAND1 connected 3200x1800+0+0 290mm x 170mm
3200x1800@0.1Hz 0.03*+
Export the refresh rate in the correct units. For improved precision,
perform the KMS intermediate calculations in milliHz as well, and
account for interlaced/doublescan modes.
This is also consistent with what GTK+ expects:
timings->refresh_interval = 16667; /* default to 1/60th of a second */
/* We pick a random output out of the outputs that the window touches
* The rate here is in milli-hertz */
int refresh_rate = _gdk_wayland_screen_get_output_refresh_rate (wayland_display->screen,
impl->outputs->data);
if (refresh_rate != 0)
timings->refresh_interval = G_GINT64_CONSTANT(1000000000) / refresh_rate;
Where the 'refresh_rate' given is exactly what's come off the wire.
1000000000/60000 comes out as 16667, whereas divided by 60 is ...
substantially less.

Failing to initialize Clutter isn't something it's useful to report

https://bugzilla.gnome.org/show_bug.cgi?id=757311
g_error() is the wrong thing to do when, for example, we can't find the
DRM device, since Mutter should just fail to start rather than reporting
a bug into automatic bug tracking systems. Rather than trying to decipher
which errors are "expected" and which not, just make all failure paths
in meta_launcher_new() return a GError out to the caller - which we make
exit(1).

Ubuntu ships a patch in the X server that makes the group switch
keybindings only work on key release, i.e. the X server internal group
locking happens on key release which means that mutter gets the
XKB_KEY_ISO_Next_Group key press event, does its XLockGroup() call
with a new index and then, on key release, the X server moves the
index further again.
We can work around this without affecting our behavior in unpatched X
servers by doing a XLockGroup() every time we're notified of the
locked group changing if it doesn't match what we requested.

We might get modes in XRROutputInfos that aren't in the

again.
In any case, when these glitches happen, we end up with NULL pointers

Calling queue_redraw() in _force_update() is not needed because

update_cursor() will cover this as well when needed. When not changing

This commits refactors cursor handling code and plugs in logic so that
cursor sprites changes appearance as it moves across the screen.
Renderers are adapted to handle the necessary functionality.
The logic for changing the cursor sprite appearance is done outside of
MetaCursorSprite, and actually where depends on what type of cursor it
is. In mutter we now have two types of cursors that may have their
appearance changed:
- Themed cursors (aka root cursors)
- wl_surface cursors
Themed cursors are created by MetaScreen and when created, when
applicable(*), it will extend the cursor via connecting to a signal
which is emitted everytime the cursor is moved. The signal handler will
calculate the expected scale given the monitor it is on and reload the
theme in a correct size when needed.
wl_surface cursors are created when a wl_surface is assigned the
"cursor" role, i.e. when a client calls wl_pointer.set_cursor. A
cursor role object is created which is connected to the cursor object
by the position signal, and will set a correct texture scale given what
monitor the cursor is on and what scale the wl_surface's active buffer
is in. It will also push new buffers to the same to the cursor object
when new ones are committed to the surface.
This commit also makes texture loading lazy, since the renderer doesn't
calculate a rectangle when the cursor position changes.
The native backend is refactored to be triple-buffered; see the comment
in meta-cursor-renderer-native.c for further explanations.

Solve this and other related issues for the nested X11 compositor

There were lots of code handling the native renderer specific cases;
move these parts to the renderer. Note that this causes the X11 case to
always generate the texture which is a waste of memory, but his
regression will be fixed in a following commit.
The lazy loading of the texture was removed because it was eventually
always loaded anyway indirectly by the renderer to calculate the

Before, it used to be in the screen, but now,
meta_cursor_reference_from_theme can never fail. Move it to where we

Since mutter has two X connections and does damage handling on the
frontend while fence triggering is done on the backend, we have a race
between XDamageSubtract() and XSyncFenceTrigger() causing missed
redraws in the GL_EXT_X11_sync_object path.
If the fence trigger gets processed first by the server, any client
drawing that happens between that and the damage subtract being
processed and is completely contained in the last damage event box
that mutter got, won't be included in the current frame nor will it
cause a new damage event.
A simple fix for this would be XSync()ing on the frontend connection
after doing all the damage subtracts but that would add a round trip
on every frame again which defeats the asynchronous design of X
fences.
Instead, if we move fence handling to the frontend we automatically
get the right ordering between damage subtracts and fence triggers.

While we shouldn't normally receive crossing events for any windows
except the stage when running nested, we do in case we hold a pointer
grab - just ignore those events instead of taking down the user's
session.
If GL advertises this extension we'll use it to synchronize X with GL
rendering instead of relying on the XSync() behavior with open source
drivers.
Some driver bugs were uncovered while working on this so if we have
had to reboot the ring a few times, something is probably wrong and
we're likely to just make things worse by continuing to try. Let's
err on the side of caution, disable ourselves and fallback to the
XSync() path in the compositor.

We should not be setting random output properties like this.
Use the function we just introduced to only set the underscan flag when
it's actually supported.
So that clients such as the control center can decide to hide an
underscanning checkbutton when the output does not support it.

It seems that fglrx sometimes gives us absolute junk when requesting the
outputs, and if we don't trap errors, we'll just crash when trying to
configure a junk output. Use xcb so errors simply get ignored.
For enter / leave events, which we use in the UI code, we need to make
sure that these coordinates are root-relative as well, otherwise the
cursor when entering frames might be incorrect.
If we're running as a nested compositor, we must not attempt to
passive grab on the root window, and we should be setting the
touch event mask on the stage window.

This way, we won't be hit with BadValue errors if we set it to a value

The monitors info structure is created from the tiled outputs
and this is used as the central storage for info about a monitor
as opposed to the output state.
It appears at least the EDID mm w/h is for the whole monitor and
not per tile.
this just adds backend support for retrieving the tile
information from X11 (randr 1.5) and native backends.
It stores the tiling information into the output struct.
This makes gnome-settings-daemon turn on the backlight and
gnome-shell's screen shield animate.
Note that on X sessions, gnome-settings-daemon uses the same upower
property to force an innocuous key event into the X server so that the

clutter currently never emits activated or deactivated signals on
the stage object when using the EGL backend. Since the stage never
gets activated, accessibility tools, like orca, don't work.
This commit makes mutter take on the responsibility, by tracking
when the stage gains/loses focus, and then synthesizing stage
CLUTTER_STAGE_STATE_ACTIVATED state events.
A limitation of this approach is that clutter's own notion of
the stage activeness won't reflect mutter's notion of the
stage activeness. This isn't a problem, in practice, and can
be addressed in the medium-term after making changes to
clutter.

On startup, the cursor is kept hidden if there's any touchscreen available.
If the device that was last interacted is removed, we check on available
pointing devices though, so we don't possibly hide the pointer if there are
further mice/touchpads/etc.
Devices being added don't update cursor visibility, we wait for the user
interacting with those instead.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
On X11, calling this function on meta_display_handle_events() will not catch
mouse events happening over clients, so poke directly in the backend for

handle_input_event() function.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
This function can be used to trigger changes depending on the device type
that is currently emitting the events. So far, it is used to switch cursor

One caveat is that meta_input_settings_create() may return NULL if the

This reverts commit 47e339b46e. The
approach that was used to reduce the amount of work we do on RR events
to the necessary minimum is flawed. It assumes that, when the first
event we see where the retrieved XRRScreenResources.timestamp is
bigger than the previous, we already have all the data we need to
rebuild our view of the world.
That isn't true however, because the X server sends
RRScreenChangeNotify events for every step of the configuration
change, i.e. it lacks an atomic reconfiguration API. In particular, if
the X screen size is one of the changes, when we rebuild our state and
emit monitors-changed, the X screen size might still be the previous
one and since we stop updating ourselves until another reconfiguration
happens (noticed by looking at XRRScreenResources.timestamp) we end up
with the wrong idea of the X screen size.
https://bugzilla.gnome.org/show_bug.cgi?id=738630
This optimization breaks our use of XRRScreenResources' timestamps to
detect hotplugs in case one of the outputs is disconnected and the
remaining ones don't need any mode, position or transform adjustments.
In that scenario, when applying the new configuration, we resize the X
screen but never call XRRSetCrtcConfig() and since XRRSetScreenSize()
doesn't take a timestamp and the X server doesn't update its last set
timestamp, when we next get a RRScreenChangeNotify and update
ourselves, XRRScreenResources.timestamp will still be smaller than
XRRScreenResources.configTimestamp which makes us think we're seeing a
new hotplug. We just don't enter an endless loop because the screen
size that we keep applying is always the same and the X server
short-circuits and stops sending us RRScreenChangeNotifys.
Always calling XRRSetCrtcConfig() ensures that the last set timestamp
will be bigger than configTimestamp in the next event and thus making
us trigger the monitors-changed signal properly.
Note that the X server already does basically the same checks that
we're removing here, so doing this shouldn't be a significant
efficiency loss. See
http://cgit.freedesktop.org/xorg/xserver/tree/randr/rrcrtc.c?h=server-1.16-branch#n539
It doesn't make sense to load cursor textures that we might not ever
use. Since the code here also uses CoglTexture2D, and cursors tend
to be NPOT textures, then we won't crash users of cards without
NPOT support. At least until they open the magnifier. :)
Refactor make_default_config() to always sanity-check the configuration to
ensure that it fits within the framebuffer. Previously, this was only done
for the default linear configuration.
In recent versions of the QXL driver, it may set "suggested X|Y" connector
properties. These properties are used to indicate the position at which
multiple displays should be aligned. If all outputs have a suggested position,
the displays are arranged according to these positions, otherwise we fall back
to the default configuration.
At the moment, we trust that the driver has chosen sane values for the
suggested position.
When the output device has hotplug_mode_update (e.g. the qxl driver used in
vms), the displays can be dynamically resized, so the current display
configuration does not often match a stored configuration. When a new
monitor is added, make_default_config() tries to create a new display
configuration by choosing a stored configuration with N-1 monitors, and then
adding a new monitor to the end of the layout. Because the stored config
doesn't match the current outputs, apply_configuration() will routinely
fail, leaving the additional display unconfigured. In this case, it's more
useful to just fall back to creating a new default configuration from
scratch so that all outputs get configured to their preferred mode.
Move logic for creating different types of configurations into separate
functions. This keeps things a bit cleaner and allows us to add alternate
configuration types more easily.
When a laptop's lid is closed we try to build and apply a temporary
configuration that disables the laptop's display if we have other
outputs.
This isn't enough though, we must also check if at least one of these
other outputs is enabled otherwise we'll try to resize the screen to
0x0 which (rightfully) hits an assertion.
https://bugzilla.gnome.org/show_bug.cgi?id=739450
It turns out that this was wrong because MetaWindow->monitor points to
the old monitor infos and they are needed to position windows in the
new configuration which happens in a monitors-changed handler.
This reverts commit e1704acda4.
The code in MetaMonitorConfig was really complex and was trying to do
way too much, using multiple different variables to determine where
things were stored, and trying to do fancy tricks to transfer
ownership.
Add a refcounting system to help simplify this, and clean up the logic.
Simply along the way, this fixes multiple bugs in the monitor config
logic, most notably bug #734889, which was my original goal to fix.
The X server sends several RRScreenChangeNotify events in a burst when
something happens which, currently, causes us to rebuild our view of
the world as many times and notify the upper layers about it which
causes a lot of bogus repeated work like rebuilding background actors.
We can avoid this extra work by looking at the timestamp in the
XRRScreenResources struct which is updated when an X client (including
us!) last changed something and comparing it with the previous
timestamp.
https://bugzilla.gnome.org/show_bug.cgi?id=738630
meta_monitor_config_match_current() only matches the number of outputs
and if the output connector, vendor, product and serial match.
In the X backend, this means that we can't use it to bypass doing any
work because it won't detect cases where we actually want to update
ourselves like e.g. an output being turned off either by us or by
another X client (e.g. xrandr).
In the native backend, unlike the xrandr backend, we only get called
on real hotplug events and thus should always trigger the common
hotplug code to (possibly) apply a new mode so the check is pointless
anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=738630
In randr events, configTimestamp can be considered the hotplug time,
i.e. whenever the server notices hardware changes, this value will be
updated.
Having that in mind, we can re-work the logic to make it clearer.
There are no semantic changes.
The code here was a bit messy with the addition of
hotplug_mode_update, and the comments were a bit confusing and
inaccurate. Clean it up and comment it a bit better to make the flow and
intention more clear.
We need to tell clutter's evdev backend about the desktop's key repeat
settings so that our own key bindings event processing and
gnome-shell's chrome widgets get their fake key events for continuous
key press as they expect.
Note that the wayland frontend filters out these events and thus
wayland clients do not see them as specced.
https://bugzilla.gnome.org/show_bug.cgi?id=728055
The X server applies a default keymap to hotplugged keyboard
devices. To enforce our current settings we must re-upload the keymap
when a new keyboard shows up.
Note that setting the VCK keymap causes the server to propagate it
to all slave keyboard devices.
https://bugzilla.gnome.org/show_bug.cgi?id=737673
We overrode the property for PowerSaveMode, which meant that gdbus's
auto-generated PropertiesChanged code wasn't being run.
This really confused gnome-rr and gnome-settings-daemon's power plugin
about the current DPMS state of the display, since they used their
cached PowerSaveMode properties, and never saw a PropertiesChanged being
emitted.
If a display was on, they set it to off, and then set it back on, the
setting back on would never fire, since they thought the display was
already off.
To fix this, remove our custom property override and just respond to
notifications on the object.
Namely, this fixes the DPMS management when receiving notifications so
that it now properly times out.
Use the new DRM capabilities to figure out the correct cursor size, and
make sure that matches instead of hardcoding 64x64. This fixes incorrect

We'll need this in the wayland frontend to send a modifiers event to

If we add device 2, then add device 254, then remove device 254, then
the max device ID will be 253. Scan through all the devices again on
removal to calculate a new max device ID.
Rather than have the DBus code control this, move this into
MetaBackend. This also lets us destroy idle monitors when appropriate,
rather than leaking them forever.
We indeed call this function if we're not an X11 compositor, but in this
case we're simply calling it to say that we have no cursor overlay. Make
sure not to assert fail in this case.
RandR's QueryOutputProperty request makes the incredible decision of
throwing a BadName if you pass a property that doesn't exist, which
means that trying to check if a property exists is a royal pain when
using Xlib.
XCB's interface is much more friendly about errors and not having global
state and things like that, so use that instead to query our backlight
property.
If the property doesn't exist, a BadName error will be generated. This
is a terrible API, but it's what we're stuck with. Use
RRGetOutputProperty instead.
We've long used a switch statement on the grab operation to determine
where events should go. The issue with MetaGrabOp is that it's a mixture
of a few different things, including event routing, state management,
and the behavior to choose during operations.
This leads to poorly defined event routing and hard-to-follow logic,
since it's sometimes unclear what should point where, and our utility
methods for determining grab operations apart can be poorly named.
To fix this, establish the concept of a "event route", which describes
where events should be routed to.
Popups could not set the cursor image, because the cursor tracker would
ignore window cursors if we had a popup active. The correct condition to
check for is already in should_block_wayland. Rename this to the more
sensible name windows_are_interactable, and use it in the cursor tracker.
meta_backend_get_keymap is supposed to return a static keymap, not a new
one every time. Cache it internally. We don't update it when the keymap
changes on the server, but we'll do this soon.
This allows creating the stage much earlier than it otherwise would have
been. Our initialization sequence has always been a bit haphazard, with
first the MetaBackend created, then the MetaDisplay, and inside of that,
the MetaScreen and MetaCompositor.
Refactor this out so that the MetaBackend creates the Clutter
stage. Besides the clarity of early initialization, we now have much
easier access to the stage, allowing us to use it for things such as
key focus and beyond.
These methods allow us to set and get xkbcommon keymaps as well as
locking a specific layout in a layout group.
With this, we introduce dependencies on xkeyboard-config, xkbfile,
xkbcommon-x11 and a libX11 new enough to have xcb support.
https://bugzilla.gnome.org/show_bug.cgi?id=734301
Sometimes we can get a host event without having the display up and
running yet. Just don't pass it to the compositor in that case, since it
won't be possible for it to have any event that matters.
This reverts commit 3b85e4b2b9.
This breaks touch support; reverting would break wayland
(is what this patch tried to fix; we should find a better solution
that works on both).
When a touch sequence is passively grabbed and later rejected, events
will be replayed on the next client in propagation order, although those
events (either transformed to pointer events or not) will contain the
original timestamps, this will make grabs fail with InvalidTime if triggered
from the replayed ButtonPress/TouchBegin handler.
In order to work around this, store the most recent event time (presumably
gotten from the XI_TouchEnd caused by the passive grab being rejected), and
use that time on the events being replayed afterwards and grabs, so we don't
possibly fail with InvalidTime if those events result in a compositor grab.
The output_id is more of an opaque identifier for the monitor, based on
its underlying ID from the windowing system. Since we also use the term
"output_id" for the output's index, rename our use of the opaque cookie
"output_id" to "winsys_id".
This makes Alt+F7 / Alt+F8 work respectively under X11 nested mode.
For the native backend implementation, we'll need a special Clutter
function, so don't implement that for now.
