It keeps references to cursors, and cursors keep references to DRM
buffers. In order to be able to clean up on exit, explicitly destroy the
cursor tracker on shutdown.
We can't rely on GObject reference counting, as gjs might hold onto a
reference until it's garbage collected.

Various things, e.g, the renderer, the stage, either directly or
indirectly depends on GPU objects being alive during tear-down. Make it
so, by moving GPU cleanup after the other cleaning. This will allow
tearing down a couple of more objects.

The first phase happens early, which discards pending page flips,
meaning the references held by those page flip closures are released.
The second phase happens late, after other units depending on the KMS
abstraction, have been cleaned up.

We already swapped the front buffer, and even if it didn't get
presented, we should still swap our representation of the state, to not
get into a confused buffer tracking state.

All pointer a11y is a fabrication of Clutter backend-independent
code, with the help of a ClutterVirtualInputDevice and with some
UI on top.
On the other hand, MetaInputSettings is a backend implementation
detail, this has 2 gotchas:
- In the native backend, the MetaInputSettings (and pointer a11y
with it) are initialized early, before the ClutterSeat core
pointer is set up.
- Doing this from the MetaInputSettings also means another dubious
access from the input thread into main thread territory.
Move the pointer a11y into ClutterSettings, making this effectively
backend-independent business, invariably done from the main thread
and ensured to happen after seat initialization.

Virtual Kernel Mode Setting (vkms) is a virtual /dev/dri/card* device
not backed by any actual hardware. It's intended for testing purposes,
e.g. to run tests suites with a reproducable setup, or in continuous
integration pipelines.
Currently mutter don't have any tests that can run on top of vkms, but
will eventually get that. To prepare for the ability to do that, and
having said kernel module loaded without causing wierd issues with any
active session, add an udev rule that tells mutter to ignore any vkms
device.
Otherwise, when vkms is loaded, mutter would detect it, assume it's a
regular monitor, configure it as such, thus add a region of the stage
that ends up nowhere, which isn't very helpful. It might also conflict
with running actual tests that need to interact with vkms if the active
session has taken control of it.

With atomic mode setting, commits don't work when CRTCs aren't enabled,
which they aren't when we're power saving. This means the gamma state
fails to being update. To fix night light and for whatever other reason
gamma ramps was changed during power saving by marking the CRTC gamma
state as invalid when leaving power saving, as well as when resuming.
This means that the next frame will append the CRTC gamma state to the
KMS commit.

This GSource is not being properly unref nor the variable holding it

may trigger warnings in keyboard_repeat() as the source may be

seat_impl->repeat_source is never NULL.

The X server generates a property change notification whenever it processes a
property change request, even if the value of the property is not changing. This
triggers libgdk to probe all display outputs, which can be slow depending on
which display driver and hardware are in use.

When GNOME is animating a display fade when the night light feature is toggled
on or off, it sends a lot of change requests for the CTM property in the
process, which triggers a lot of display probes from gdk. In the case of the
night light feature, the CTM itself is not actually changing, so these requests
are redundant. Fix this by caching the CTM value in the MetaOutputXrandr and
skipping the server requests if it's not being changed.

When we set the matrix, we checked the device mapping mode in the main
thread, then passed along the calculated matrix to the input thread for
application. This could however be racy, as the mapping mode is managed
in the input thread. Fix this by sending the unaltered matrix, having
the input thread checking the mapping mode.

The connector state wasn't properly predicted, as it earlied out if
the connector wasn't part of a mode set connector list.
Instead use the old CRTC to check whether it was used in any mode set,
and whether the connector was part of any new mode set, to predict
whether the connector is inactive or active.

On hybrid graphics system, the primary path used to transfer the stage
framebuffer onto the dedicated GPU's video memory preparing for scanout,
is using the dedicated GPU to glBlitFramebuffer() the content from the
iGPU texture onto the scanout buffer.
After we have done this, we reset the current EGL context back to the
one managed by cogl. What we failed to do, however, was to reset the
current EGL context when we inhibited the actual page flip due to having
entered power save mode.
When we later started to paint again, Cogl thought the current EGL
context was still the correct one, but in fact it was the one used for
the iGPU -> dGPU blit, causing various EGL surface errors, and as a side
effect, eventually hitting an assert.
Fix this by making sure we reset to the Cogl managed EGL context also
for this case.

Destroying the EGLSurface frees the underlying container structs. When
we call gbm_surface_release_buffer() with a gbm_surface the EGLSurface
was created from, doing that after the EGLSurface was destroyed results
in attempts to access freed memory. Fix this by releasing any buffer
first, followed by destroying the EGLSurface, and lastly, the
gbm_surface.
This was not a problem prior to CoglOnscreen turning into a GObject, as
in that case, the dispose-chain was not setup correctly, and the
EGLSurface destruction was done in the native backend implementation.
This also changes a g_return_if_fail() to a g_warn_if_fail(), as if we
hit the unexpected case, we still need to call up to the parent dispose
vfunc to not cause critical issues.

It's handled by CoglOnscreenEgl's dispose() implementation. It was
failed to be invoked in the past because the old non-GObject web of
vtables were not setup correctly, meaning the old generic EGL layer of
the CoglOnscreen de-init was never invoked.
When the type inheritence was cleaned up, this mistake was not cleaned
up, so do that now.

Meson doesn't seem to handle depending on generated headers, at least
when those headers are pulled in indirectly via another header file.
Luckily, we don't actually need to include the generated D-Bus boiler
plate in meta-monitor-manager-private.h, since the MetaMonitorManager
type no longer is based on the D-Bus service skeleton.
So, by moving the inclusion of the generated D-Bus header file into
meta-monitor-manager.c, we should hopefully get rid of the sporadic
build issues.

If there was only a single mode, add the common modes to provide options
to select other resolutions than the built in default. This avoids
issues where the connector listed multiple supported modes, but where
the common modes added would exceed the possible bandwidth. We could
probably make an attempt to filter out more modes from the common mode
list to avoid these issues, but it's likely that the driver already
lists suitable modes, meaning there is no point in adding the common
modes.
The common modes were initially added[0] to add modes to connectors with
a single bundled mode, so we shouldn't regress the original bug fix.

The intel DRM driver is known for not being able to handle multi head
setups when KMS modifiers are enabled, due to the implicitly selected
modifiers, while being more suitable for single head setups, cause
bandwidth issues when a certain number of monitor times resolution and
refresh rate is configured.
We don't yet support automatically finding a combination of modifiers
that work, and have because of this disabled KMS modifiers unless the
driver actually needs it.
Lets flip this configuration the other way around, changing the current
udev rule to decide wen to *disable* KMS modifier support, as it so that
only the Intel driver has this problem, while on the other hand, there
several drivers that requires modifiers to function at all.
