We create a cursor renderer per device for those at
meta_seat_native_handle_event_post() with PROXIMITY_IN events, but
the MetaWaylandTabletTool handles the event before that, and goes
with a NULL cursor renderer.
Make MetaBackend::get_cursor_renderer() on the native backend create
those cursor renderers on demand, and only handle PROXIMITY_OUT in
handle_event_post() to dispose those. This makes MetaWaylandTabletTool

We now only enable DMA buffer based PipeWire screen casting if a
format/modifier has been negotiated. This practically means a consumer
is aware about what is needed, and we should not try to predict that it
uses the DMA buffer the right way (i.e. not mmap:ing directly).
However, in case we're not hardware accelerated, we never want to
attempt to use DMA buffer screen sharing, as we want to avoid
compositing into a DMA buffer on such hardware as doing so can be very
slow.

When handling lid state, we used to update the idle time right after
opening the lid. This behavior changed in commit 14b6c8780d due
to a typo/thinko, "if (lid_is_closed)" used to be an early return
condition before updating idle time, now it only updates in that
case.
Restore the original behavior, since this idle time update is key
in having gsd-power light up the display again, this presumably
fixes situations that required extra "light up" hints after suspend.
What it does surely fix is "ninja test" in g-s-d against recent
mutter, since the behavioral change induced a test timeout there.

Returns TRUE if the active renderer backend can allocate DMA buffers.
This is the case hardware accelerated GBM backends, but FALSE for
surfaceless (i.e. no render node) and EGLDevice (legacy NVIDIA paths).
While software based gbm devices can allocate DMA buffers, we don't want
to allocate them for offscreen rendering, as we really only use these
for inter process transfers, and as buffers allocated for scanout
doesn't use the relevant API, making it return FALSE for these solves
that.

Because both code paths require the existence of `GL_TIMESTAMP[_EXT]`
which is only guaranteed if `ARB_timer_query` (included in GL core 3.3)
is implemented.
We know when that is true because `context->glGenQueries` and
`context->glQueryCounter` are non-NULL. So that is the minimum
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).

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

Fix this by making sure the string length is correct first. Also move it

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

When the hardware has not an explicit hotkey signal but we record a
change we must still fallback to this case.

In some cases mutter is started in the user scope from a TTY (for

There was a sanity check that complained if there was still a "next
framebuffer" when disposing an onscreen. This is correct to complain
about under normal operation, as we always wait until receiving the page
flip callback before cleaning up the onscreen and their state.
However, when there are many hotplugs occurring, we might end up with
race conditions when the above sanity check is not valid: when we have
more than one monitor active, paint 1 one of them, but receive a hotplug
event before we paint the other(s), we will discard the already painted
onscreen before really issuing a page flip.
In this situation, we will have the "next framebuffer", but having that
is not a bug, it's a race condition, thus to not leak in this situation,
make sure to clean up the next framebuffer here too.

If there are any pending updates, for example if we painted one of
multiple monitors but without having posted the update due to waiting
for another monitor to be painted, but before we paint all of them and
post the update, another hotplug event happens, we'd have stale pending
KMS update. When that update eventually would be processed, we'd try to
apply out-of-date updates which may contain freed memory.
Fix this by discarding any update when we're rebuilding the views. We
can be sure not to need any of the old updates since we're rebuilding
the whole content anyway.

When the before-paint function is executed, it's only purpose
is to check if there's any scanout queue, and immediately
record it if any.
However, since [1], we regressed in this specific case with the
introduction of an idle callback in the before-paint function.
The regression only happens when the PipeWire stream is using
DMA-BUF buffers, and it would operate as follows:
1. In before-paint, when there's a scanout available, we queue
an idle callback to capture the monitor. The idle callback
(almost always) executes after the scanout is pulled from
the stage view
2. meta_screen_cast_stream_src_maybe_record_frame() is called
by the idle callback. In the DMA-BUF case, it then runs
meta_screen_cast_monitor_stream_src_record_to_framebuffer()
3. In meta_screen_cast_monitor_stream_src_record_to_framebuffer(),
because the stage view doesn't have a scanout anymore, it
ends up calling cogl_blit_framebuffer() with the stage view
framebuffer. This is the regression bug.
This regression presents itself in the form of the screencast
stream showing the desktop when there's an unredirected fullscreen
application window running.
Revert before-paint - and only that - back to immediately capturing
any available scanout. Only record these frames when the target
buffer is a DMA-BUF handle. Nothing is captured on before-paint if
the stream is not using DMA-BUF, since the regular paint routine
will handle these frames regularly post-paint.

This API can be used to construct a MetaKmsUpdate with plane assignments
that in isolation will be tested against the current KMS state. How it
is tested depends on the KMS implementation; in the simple / legacy KMS
backend, the tests are identical to the current scanout requirements
(dimension, stride, format, modifiers, all must match), and with atomic
KMS, it uses the TEST_ONLY on a real constructed atomic mode setting

Commit 2289f56112 ("monitor-manager: Don't apply unneeded orientation

the transform is unchanged.
But this did not take the correction of the transform for devices

change to get skipped if the new orientation matches the corrected
logical orientation from the previous transform setting.
Fix this by calling meta_monitor_crtc_to_logical_transform () on the

create_for_builtin_display_rotation ().

This is a strange thing to do since MetaInputMapper also does take care of
devices with an output configured through settings, since we might have

This was essentially here as a last resort to avoid matching two very
similar looking tablets to one of two very similar looking outputs. There

It was dropping to zero after the first frame because it hadn't been
incremented high enough. So the second frame would crash with:
```
#0 g_type_check_instance_cast
#1 META_DRM_BUFFER
#2 copy_shared_framebuffer_cpu
```
That's the CPU-copy path (fallback-fallback) that probably no one is using
but it does work after this fix. Exactly the same issue as was fixed
in `copy_shared_framebuffer_primary_gpu` by 36352f44f9.

If some connectors disappeared, but the rest didn't change, we missed
actually removing the ones that disappeared, as we incorrectly assumed
nothing changed. Fix this by only assuming nothing changed if 1) we
didn't add any connector, and 2) we have the same amount of connectors
as before the hotplug event. The connector comparison checking makes
sure we report changes if anything of the still available connectors
changed.

When a docking station is disconnected, a few previously existing DRM
connectors may now be gone. When this happens, getting them via the
libdrm API results in NULL pointers returning, and we need to handle
this gracefully by making sure the connector state is properly updated.

Systems with AMD GPUs do not take advantage of Mutter's zero-copy path
when driving DisplayLink screens. This is due to a very slow CPU access
to the zero-copy texture. Instead they fall back on primary GPU doing a
copy of the texture for fast CPU access. This commit accelerates texture
copy by working through damage regions only.
Tests on a 4K screen with windowed applications show significant
reduction of GPU utilisation.

Certains keys (such as ~ and |) are in the keyboard map behind the
second shift level. This means in order for them to be input, the
shift key needs to be held down by the user.
The GNOME Shell on-screen keyboard presents these keys separately on
a page of keys that has no shift key. Instead, it relies on mutter
to set a shift latch before the key event is emitted. A shift latch
is a virtual press of the shift key that automatically gets released
after the next key press (in our case the ~ or | key).
The problem is using a shift latch doesn't work very well in the face
of key repeat. The latch is automatically released after the first
press, and subsequent repeats of that press no longer have shift
latched to them.
This commit fixes the problem by using a shift lock instead of a shift
latch. A shift lock is never implicitly released, so it remains
in place for the duration of key repeat.

The `guess_candidates()` function scores each display that an input
device could be mapped to and then uses the `sort_by_score()` comparator
to find the best option. The function expects the list to be sorted from
best to worst, but the comparator currently sorts them in the opposite
order. This causes the function to end up returning the _worst_ match
rather than the the best. This commit reverses the sort order of the
comparator so that the best display can be returned as intended.

Mutter already calculates and tracks the damage rectangles to redraw
only areas of the screen that change since the last time a buffer was
used.
This patch extends this by using the EGL_KHR_partial_update extension to
inform the GPU in advance that only those areas will be changed, which
may allow for further optimization.

When we use gbm together with the NVIDIA driver, we want the EGL/Vulkan
clients to do the same, instead of using the EGLStream paths. To achieve
that, make sure to only initialize the EGLStream controller when we
didn't end up using gbm as the renderer backend.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2052>
This switches the order of what renderer mode is tried first, so that
the gbm renderer mode is preferred on an NVIDIA driver where it is
supported.
We fall back to still try the EGLDevice renderer mode if the created gbm
renderer is not hardware accelerated.
The last fallback is still to use the gbm renderer, even if it is not
hardware accelerated, as this is needed when hardware acceleration isn't
available at all. The original reason for the old order was due to the
fact that a gbm renderer without hardware acceleration would succeed
even on NVIDIA driver that didn't support gbm.

This replaces functionality that MetaRenderDevice and friends has

It might not be needed by the user of the buffer, so don't always
require it up front. Instead make sure that any user that needs it first
calls "meta_drm_buffer_ensure_fb_id()" to create the ID.
Only the plain gbm implementation creates the ID lazilly, the other
still does it on construction due to the objects used to create them
only existing during construction.

Mostly calls into gbm_bo_* API, or something somewhat similar when on

The purpose of MetaRenderDevice is to contain the logics related to a

It was a feature relevant for when Clutter was an application toolkit
that wanted the application window to communicate a minimum size to the
windowing system.
Now, clutter is part of the windowing system component, so this feature
doesn't make any sense, so remove it.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2002>
This changes the setup phase of clutter to not be result of calling an
init function that sets up a few global singletons, via global singleton
setup vfuncs.
The way it worked was that mutter first did some initial setup
(connecting to the X11 server), then set a "custom backend" setup vfunc
global, before calling clutter_init().
During the clutter_init() call, the context and backend was setup by
calling the global singleton getters, which implicitly created the
backend and context on-demand.
This has now changed to mutter explicitly creating a `ClutterContext`
(which is actually a `ClutterMainContext`, but with the name shortened to
be consistent with `CoglContext` and `MetaContext`), calling it with a
backend constructor vfunc and user data pointer.
This function now explicitly creates the backend, without having to go
via the previously set global vfunc.
This changes the behavior of some "get_default()" like functions, which
will now fail if called after mutter has shut down, as when it does so,
it now destroys the backends and contexts, not only its own, but the
clutter ones too.
The "ownership" of the clutter backend is also moved to
`ClutterContext`, and MetaBackend is changed to fetch it via the clutter
context.
This also removed the unused option parsing that existed in clutter.
In some places, NULL checks for fetching the clutter context, or
backend, and fetching the cogl context from the clutter backend, had to
be added.
The reason for this is that some code that handles EGL contexts attempts
to restore the cogl EGL context tracking so that the right EGL context
is used by cogl the next time. This makes no sense to do before Cogl and
Clutter are even initialized, which was the case. It wasn't noticed
because the relevant singletons were initialized on demand via their
"getters".

In various places we retrieved the default seat from the ClutterBackend.
All the clutter backends implement this by calling

Rename all instances of `MetaClutterBackendX11` so they are called

meta_keymap_x11_replace_keycode currently reports to the X server
that the key types data is changed when adding a key to the keymap.
It's not changed. The number of key types is the same, and none of
them are modified.
This has two bad side effects:
1) It sends all of the key types data into the request
2) It hits a bug in the X server leading to the request getting
rejected entirely. See:
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/761
Furthmore, the changed structure used to report to the X server
that the key types data is changed doesn't actually need to modified
at all in the function. It's already prepped by libX11 with the
correct state for the changes mutter is doing when
XkbChangeTypesOfKey is called.
This commit addresses the above two problems by just removing the
lines causing the issues.

Keys in the reserved keycode list are always added for the first group.
Before the previous commit such keycodes were not found unless that was
the current group. But now that we can also find matching keycodes that
are not directly in the current group, this is not necessary anymore.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1955>
Some keys, such as enter or backspace are only bound to a single group,
even if multiple groups are configured. Because the code was previously
only looking for keysyms in the same group as the current one, no
matching keycodes for these would be found if the current group is not
the first group. This was causing those keys to not work on the X11 OSK.
To fix this use the correct action to convert an out of range group for
that key according to its group_info field.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1955>
This effectively changes meta_keymap_x11_get_entries_for_keyval() to
meta_keymap_x11_get_entry_for_keyval() and moves the check if the
keycode maps to the keyval in the current group there. This simplifies
the code a bit and will allow a followup fix.
As a side effect this now also causes the reserved kecodes to be
searched, if no keycodes were found, rather than just when only ones
matching the wrong groups.

Avoid having laptops suspend or lock as soon as the power cable is
unplugged as the timeout for those actions when on battery are smaller
than the timeouts when on AC.
- laptop is plugged in, and hasn't been used for X minutes
- laptop is unplugged
- the gnome-settings-daemon power plugin sets up its timeouts for
inactivity for the "on battery" case
- those X minutes of inactivity are still counting, and are above
the level of one of the timeouts (say, suspend or lock screen),
mutter fires the timeouts
- gsd-power activates the action associated with the timeout

When the native backend is paused we still process the udev events
even though this isn't needed and may just cause unneeded events to be
triggered afterwards.
Since we'll resume with full changes on such event, we can just block
the signal hander when paused and restore it afterwards.
As per this we can cleanup also a bit the device adding signal handling
given that now we don't have to disconnect/reconnect it again.

Resume happens after we may have received various events that we've

Hotplug events may contain CRTC or CONNECTOR ids to notify a property

If only gamma changed on drm CRTC's we don't have to rebuild the whole
monitors, nor to inform the backed about, the only consumer could be the
DBus API, and so we still emit a signal, but nothing else is needed.

Since we cache already all the KMS parameters we care about let's check at
each device update if anything has really changed and only in such case
emit a resources-changed signal.
In this way we can also filter out the DRM parameters that when changed
don't require a full monitors rebuild.
Examples are the gamma settings or the privacy screen parameters, that
emits an udev "hotplug" event when changed, but we want to register those
only when we handle the changed property.

In X11 when we switch to another tty all the the signals are blocked (as
the display fd is not replying back to polling, causing the main loop to
stop), and they are all handled once we switch back to the tty.
This is not a problem for most of external events, but in case of
accelerometer changes, once we reactivate a mutter session we'll get
them all together, causing lots of monitor reconfigurations leading to
black screen for some seconds and most of the times to a wrong
configuration being applied.
To avoid this, batch all these events using an idle to only apply the
last one we got in a loop.

Create a test system bus and use it to run all the tests, add a mock
SensorsProxy (via dbusmock template) server that implements the
net.hadess.SensorProxy interface.
To make testing easier, the service is created on request of a proxy for
it, whose lifetime controls the mock service lifetime as well.
This is done using a further mock service that is used to manage the
others, using python-dbusmock to simplify the handling.
Add basic tests for the orientation manager.
As per the usage dbusmock, we're now launching all the tests under such

When creating the configuration for the builtin monitor we try to get
the panel configuration for the builtin panel, but we don't proceed if
that monitor is currently inactive.
This is fine when adjusting an active configuration to the current
device rotation, but it isn't correct when we want to create a new
configuration based on another where the monitor is configured but not
yet enabled.
So, only find the panel configuration without looking the current state
but ensuring that the passed configuration will enable it.

When we get an orientation event we don't care about keeping track of the
configuration changes, but actually we can consider the new configuration
just a variant of the previous one, adapted to floating device hardware
events, so we only want to apply it if possible, but we don't want to keep
a record of it for reverting capabilities.
Doing that would in fact, break the ability of reverting back to an actual
temporary or persistent configuration.
For example when device orientation events happen while we're waiting for
an user resolution change confirmation, we would save our new rotated
configuration in the history, making then impossible to revert back to
the original persistent one.
So in such case, don't keep track of those configurations in the history,
but only keep track of the last one as current, checking whether the
new current is child or sibling of the previously one.

When creating a configuration taking orientation into account we're using
the sensors orientation even if this is currently not used (for example
