Unfortunately we cannot do this generically since the target of the
button/touch press does matter, e.g. tapping on the OSK, or clicking
the IBus candidates window. These situations should not trigger a
reset.
So be more selective about the situations where button/touch presses
trigger an IM reset, in the case of ClutterText these are still clicks
inside the actor, for Wayland's text-input it is when clicking the
surface that has text_input focus.
For all other situations where clicking anywhere else might make
sense to trigger an IM reset are covered by the focus changing paths,
that also ensure a reset before changing focus between surfaces/actors.

Focus changes should trigger an IM reset, as some engines do want
to maybe commit the preedit string before changing focus. In addition,
we do not want the preedit string to be able to move between
windows/applications.
Ensure that the commit string is committed when the IM deems so, and
ensure we send a .done event disntinct to the .leave event, so that
the client doesn't miss the commit.

As of currently, we only emit .done() on actual changes coming from the

When switching between the existence and not of a stage ClutterGrab, we
would correctly attempt to synchronize key focus from the perspective of

But this synchronization should do its own checks about existing stage

Add that check, so that grabs correctly unfocus the keyboard in Wayland
clients, in addition to pointers and touch.

With Xwayland on demand, a number of maintenance X11 applications need
to be run first, before Xwayland starts accepting requests from the
normal clients, as soon as the WM_S0 selection is acquired by mutter.
On startup, mutter also sets a number of X11 properties that can be
queried by X11 clients.
Unfortunately, mutter acquires the WM_S0 selection before setting those
properties, so mutter and the first regular X11 client will race on
startup.
As a result, the X11 properties set by mutter on startup may not be
available to the very first X11 client when Xwayland starts.
To avoid that issue, make sure to take the WM_S0 selection last when
opening the display.

Currently, meta_xwayland_shutdown_dnd() is called from the handler
on_x11_display_closing() triggered from the signal "x11-display-closing"
hooked up from meta_xwayland_init_display().
Once the signal has been triggered, on_x11_display_closing() removes the
signal handler, disconnecting from the signal.
As meta_xwayland_init_display() is called from meta_display_new() which
is issued only once, the signal handler is not restored again.
As a result, meta_xwayland_shutdown_dnd() is not called anymore after
Xwayland has been restarted, but meta_xwayland_init_dnd() will check and
assert that the manager's DND object is NULL.
Basically, restarting Xwayland more that once will trigger an assertion
failure in mutter. That's even more of a problem with autoclose-xwayland
where Xwayland is expected to terminate when there is no meaningful X11
client remaining, which can happen multiple times during the lifetime
of a user session.
To make sure that meta_xwayland_init_display() is called for every new
instance of Xwayland, simply keep the signal hooked in place by not
disconnecting it when triggered.
This reverts commit 9a10b8ff94.
Even though, originally, this issue was first introduced with commit
b4fe1fdd95 ("xwayland: Make setup/teardown
a bit more symmetrical") which didn't actually kept 'x11-display-setup'

Since devices may be multiple things now, check all capabilities in order
to ensure all aspects of the device are correctly configured.
This change does the following observations:
- Devices that have TOUCHPAD | POINTER capabilities prefer the 'touchpad'
settings path. The regular pointer settings path is left for all
non-touchpads.
- Devices that are both a tablet and a touchscreen prefer the tablet
relocatable schema. This works for both aspects as the touchscreen
schema is a subset of the tablet one.

We use meta_workpace_focus_default_window() to sync the input focus back
to a window after it was on shell UI, this is not really necessary on
Wayland, but it is on X11. What this function does internally is ask
MetaWindowStack about the topmost window and focus+raise that window.
In gnome-shell we set the input focus to the default window every time
the key-focus changes to NULL (see shell-global.c ->
sync_stage_window_focus()). Now when closing the alt-tab switcher and
activating a window while there's an always-on-top window on the
workspace, meta_workspace_focus_default_window() will focus that
always-on-top window right after closing the alt-tab switcher, making it
impossible to focus another window using alt-tab.
To fix this, make meta_workspace_focus_default_window() check if there's
an existing focus_window first, if there is, use that, and if there
isn't, resort to just focusing the topmost one.

We use get_window_for_event() to check whether an event happened on top
of a window or on top of shell UI to decide whether to bypass delivering
the event to Clutter. In case of crossing events though, we can't just
use the device actor to determine whether to forward the event to
Clutter or not: We do want to forward CLUTTER_LEAVE events which
happened on top of shell UI. In that case the device actor is already a
window actor (the pointer already is on top of a window), but the shell
still needs to get the LEAVE crossing event.
Since the event source actor got removed from the detail of
ClutterEvent, the context we're looking for (which actor did the pointer
leave) is now the target actor that the event gets emitted to. Since the
last commit, we also made event filters aware of this context by passing
the target actor to them, so use this context now to determine whether
we're on top of a window or not.

Prior to 67033b0a mutter was accidentally including sizes for
configurations that were just focus state changes. This was not leading
to any known problems on the client side, but it was causing issues in
mutter itself when detecting whether a resize originated from the client
or the server.
Not including sizes in focus change configurations anymore however
revealed a bug in gtk. It was storing the window size when in a fixed
size mode (tiled/maximized/fullscreen), but not on any other server side
resizes. It was then restoring this stored size whenever there was a new
configuration without a size while in floating mode, i.e. the focus
change configurations generated by mutter after 67033b0a.
This change now addresses the issue 67033b0a was fixing in a way that
restores the previous behavior of always including the size whenever

If the remote desktop service emits absolute input events (e.g. absolute

When a drag and drop occurs from an X11 client to a Wayland native
client, mutter uses an internal X11 window as a peer for the DnD drop
site.
That internal X11 window is moved and resized to match the Wayland
native windows as the drag destination moves.
When moving from one Wayland native window to another Wayland native
window, the same X11 window is used, and as a result no DND enter/leave
events is emitted.
In that case, the drop may occur on the wrong Wayland native window,
because no new XdndEnter/XdndLeave event were emitted.
To avoid that issue, use a pair of X11 windows instead of just one and
alternate between the two when repicking a new drop surface, so that
moving from a Wayland surface to another will always generate the
expected enter/leave events that we rely on.

requirement for any use of `GL_TIMESTAMP`, even when it is used in
`glGetInteger64v`.
Until now, Raspberry Pi (OpenGL 2.1) would find a working implementation
of `glGetInteger64v` but failed to check whether the driver understands
`GL_TIMESTAMP` (it doesn't).

When using Xwayland-on-demand (default), if the (experimental) autoclose
features is enabled, we can rely on Xwayland's auto-terminate feature
instead of explicitly killing the Xwayland process.
With it, gone is the mechanism that was added to check the X11 clients
connected and their executable to check whether we can (safely) kill
Xwayland.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1794>
The connection to the Xserver for the X11 window manager part of mutter
even on Wayland may prevent the Xserver from shutting down.
Currently, what mutter does is to check the X11 clients still connected
to Xwayland using the XRes extension, with a list of X11 clients that
can be safely ignored (typically the GNOME XSettings daemon, the IBus
daemon, pulseaudio and even mutter window manager itself).
When there is just those known clients remaining, mutter would kill
Xwayland automatically.
But that's racy, because between the time mutter checks with Xwayland
the remaining clients and the time it actually kills the process, a new
X11 client might have come along and won't be able to connect to
Xwayland that mutter is just about to kill.
Because of that, the feature “autoclose-xwayland” is marked as an
experimental feature in mutter and not enabled by default.
Thankfully, the Xserver has all it takes to manage that already, and
is even capable of terminating itself once all X11 clients are gone (the
-terminate option on the command line).
With XFixes version 6, the X11 clients can declare themselves
"terminatable", so that the Xserver could simply ignore those X11
clients when checking the remaining clients and terminate itself
automatically.
Use that mechanism to declare mutter's own connection to the Xserver as
"terminatable" when Xwayland is started on demand so that it won't hold
Xwayland alive for the sole purpose of mutter itself.

Adding a <dbus/> element containing a boolean (yes/no) determines
whether org.gnome.Mutter.DisplayConfig ApplyMonitorsConfig will be
callable. The state is also introspectable via the
ApplyMonitorsConfigAllowed property on the same interface.
For example
<monitors version="2">
<policy>
<dbus>no</dbus>
</policy>
</monitors>
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2030>
The test aims to verify that setting the following policy
<policy>
<stores>
<store>system</store>
</stores>
</policy>
only applies monitor configurations from the system level.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2030>
This adds a way to define a way, at the system level, to define a policy
of how monitor configuration files are loaded.
The intended use case is to e.g. either prefer system level monitor
configurations before user levels, or only allow system level
configurations.
Examples:
Prefer system over user level configurations:
<monitors version="2">
<policy>
<stores>
<store>system</store>
<store>user</store>
</stores>
</policy>
<configuration>
...
</configuration>
</monitors>
Only allow system level configurations:
<monitors version="2">
<policy>
<stores>
<store>system</store>
</stores>
</policy>
<configuration>
...
</configuration>
</monitors>

strncmp() always return 0 if the passed length is 0. What this means is
that whatever the first string check happens to be, if the parsed XML
cdata was empty (e.g. if we got <element></element>), the first
condition would evaluate to true, which is rather unexpected.
Fix this by making sure the string length is correct first. Also move it
into a helper so we don't need to repeat the same strlen() check every
time.

The way device backends implement power saving differ, and power saving
needs to contain nothing incompatible in the same update. Make it
impossible to e.g. mode set, page flip, etc while entering power save by
not using MetaKmsUpdate's at all for this.

When we're predicting state, i.e. when having posted an update while
avoiding reading KMS state, copy the predicted state, update the actual
state, and check that the predicted state matches the newly updated one.

It was a bit scattered, with it being split between MetaKms and
MetaKmsImpl, dealing with MetaKmsDevice and MetaKmsImplDevice
differentation. Replace this by, for now, single entry point on
MetaKmsDevice: meta_kms_device_process_update_sync() that does the right
thing.

As other KMS tests, depends on being DRM master and vkms being loaded.

Right now gamma is set only via the D-Bus API (from gsd-color), but the
actual gamma isn't right after SetCrtcGamma(), meaning if one would call
GetCrtcGamma() right after setting it, one would get the old result.
Avoid this by getting the "current" CRTC gamma from the cache we manage.

In order to support dynamic imports, gjs added an implicit mainloop
that can drive the main context independently from other mainloops
like the one from GApplication or MetaContext.
That means that sources can now get dispatched to the main context
from the moment the plugin is started, resulting in a crash as the
association between compositor and plugin manager doesn't exist until
meta_plugin_manager_new() returns.
Make sure this doesn't happen by only starting the plugin after
meta_plugin_manager_new() has returned.

When privacy screen is changed and this happens on explicit user request
(that is not a setting change) we should notify about this via an OSD.
To perform this, we keep track of the reason that lead to a privacy
screen change, and when we record it we try to notify the user about.
When the hardware has not an explicit hotkey signal but we record a
change we must still fallback to this case.

Privacy screen events on connector are handled as notification events
that won't cause any monitors reconfiguration but will emit monitors
changed on DBus, so that the new value can be fetched.
We monitor the hardware state so that we can also handle the case of
devices with hw-switchers only.
In case a software state is available it means we can also support
changing the state, and if so expose the state as unlocked.

When both a setting change and a monitor change happens we need to
ensure that the monitor settings are applied.
This is currently only related to privacy settings, but will in future
also handle other monitor parameters such as brightness.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1952>
Some monitors support hardware features to enable the privacy screen
mode that allows users to toggle (via software or hardware button) a
state in which the display may be harder to see to people not sitting
in front of it.
Expose then this capability to the monitor level so that we can get its
state and set it.

In some cases mutter is started in the user scope from a TTY (for
example using toolbox). Using sd_pid_get_session fails because it's not
in the session scope so it falls back to the primary session
(sd_uid_get_display). We want to start mutter on the TTY we started
mutter on however. Instead of relying on the scope to figure out the
correct session we first look at $XDG_SESSION_ID which is set by
systemd_pam.so.

It is possible that we never create a cached state for a surface
even if it is synced. That is the case if `commit()` is never called.
We still need to call `apply_state()` in this case in order to run
e.g. `role_post_apply_state()` or `parent_state_applied` on subsurfaces.
So just ensure to initialize the cached state instead of bailing out.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2232>
Subsurfaces can be effectively synced indirectly via their ancestors.
Right now such indirectly synced surfaces don't apply their cached
state when their ancestor effectively becomes desync as by the time
we call `parent_state_applied()` on them, they are considered as
desync.
Thus sligthly reoder things so when the ancestors becomes desync
and applies its state, those surfaces still count as synced and
will thus apply their cached state as well.
While on it, add a check to prevent `set_desync()` to have side
effects when the target surface is not currently synced.

At first glance the `goto` looks like a loop, or potentially an infinite
loop. It's not a loop because the mode has changed at that point to
`META_SHARED_FRAMEBUFFER_COPY_MODE_PRIMARY`. But we can make it more
obvious and avoid the need for a goto.
