70e44c281c backends/native: Ensure pointer is onscreen in input thread
It's slightly racy to have the main thread update the views and warp
the pointer, since the input thread may not be aware yet of the new
viewport layout.

Make the input thread clamp the pointer so it remains onscreen
instead, when the new viewports are obtained.

1cc786ffd3 launcher: Pass fallback session/seat ID when in test mode
When we test, we might not have a systemd session to rely on, and this

changing the existing "mode" boolean ('headless') to a mode, which is
either 'default' or 'headless'. Checking the is_headless variable is
changed to using the function is_headless(), except for one place, being
VT switching, which in preparation is only allowed on the 'default'
mode. Other places where it makes sense, the conditions are changed to

719a6c0006 egl: Don't set an error when there is none
Some API will return NULL or the equivalent; sometimes it's an error,
and sometimes it's not, and the way to check that is by looking at the
return value of eglGetError(). When we check this, don't set the GError
if it returned EGL_SUCCESS, as that indicates that the return value is
expected behavior, and not an error.

bb6ae40a0f onscreen/native: Always free the next framebuffer on dispose
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.

8e91c6295d renderer/native: Clear old KMS updates on views rebuild
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.

a82dd68605 backends: Don't include damage history in swap region
Following the EGL_KHR_swap_buffers_with_damage specification, the
surface damage used by eglSwapBuffersWithDamage does not need to
contain the damage history.
Rework that to reduce the amount of rectangles that get passed to
the backend.

Also rework some of the regions that were using fb_clip_region and
missing the last scaling to support fractional scaling.

77d5c8c928 screen-cast/monitor-stream: Immediately record scanout frames
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

287908e05a renderer/native: Don't clear GPU data with pending page flips
An incorrect assumption that after mode set there would be no pending

still in the air. It fixes crashes with backtraces such as

cc9bb7c516 monitor-manager: Fix orientation changes on devices with 90° mounted panels
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
with 90° mounted panels into account causing a desired orientation
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
transform before comparing it, matching the
meta_monitor_crtc_to_logical_transform () call in
create_for_builtin_display_rotation ().

67a27a82d9 backends: Do not exclude devices from an output based on capability
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
devices that were configure through settings exclude other devices that
belong together with an output (e.g. a display-integrated tablet).

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
was a 50% chance already that the choice was wrong, and now these devices
can all be configured specifically through settings, so this shouldn't
be missed either.

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.

6060b6a240 backends/x11: Fix key repeat of on-screen keyboard for second level keysyms
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.

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.

8008f0b7b0 Explicitly create the clutter context and backend
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".

c1f5e57f2b keymap-x11: Don't update key types when adding key to keymap
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

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.

2740f1d2d2 keymap/x11: Stop searching through reserved keycodes explicitly
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.

795418a5db keymap/x11: Consider the out of range group action
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.

bb24e4ac9e keymap/x11: Check for the group earlier when finding keycode from keyval
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.

9179d4a4b1 kms/impl-device/atomic: Add virtio_gpu to deny list
virtio_gpu is used in virtual machine environments, meaning they need
accurate cursor hotspots, which currently needs non-atomic mode setting.

c789b6be38 backend: Reset idletime when unplugging the power cable
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
