Previously, trackballs were detected based on the presence of the
substring "trackball" in the device name. This had the downside of
missing devices, such as the Kensington Expert Mouse, which don't have
"trackball" in their names.
Rather than depending on the device name, use the ID_INPUT_TRACKBALL
property from udev to determine whether or not to treat a device as a
trackball.
This adds a new function, `is_trackball_device`, to MetaInputEvents, and
eliminates the `meta_input_device_is_trackball` function.

The "backends: Move MetaOutput::crtc field into private struct"
accidentally changed the view transform calculation code to assume that
"MetaCrtc::transform" corresponds to the transform of the CRTC; so is
not the case yet; one must calculate the transform from the logical
monitor, and check whether it is supported by the CRTC using
meta_monitor_manager_is_transform_handled(). This commit restores the
old behaviour that doesn't use MetaCrtc::transform when calculating the
view transform.

We need a way for mutter to exit if no available GPUs are going to work.
For example if gdm starts gnome-shell and we're using a DRM driver that
doesn't work with KMS then we should exit so that GDM can try with Xorg,
rather than operating in headless mode.

meta_backend_x11_grab_device is performing X server clock comparison
using the MAX macro, which comes down to a simple greater-than.
Use XSERVER_TIME_IS_BEFORE, which is a better macro for X server
clock comparisons, as it accounts for 32-bit wrap-around.

Commit c0d9b08ef9 replaced the old GBM API calls
with the multi-plane GBM API. However, the call to gbm_bo_get_handle_for_plane
fails for some DRI drivers (in particular i915). Due to missing error checks,
the subsequent call to drmModeAddFB[2] fails and the screen output locks up.
This commit adds the missing error checks and falls back to the old GBM API
(non-planar) if necessary.
v5: test success of gbm_bo_get_handle_for_plane instead of errno
This commit adopts solution proposed by Daniel van Vugt to check the return
value of gbm_bo_get_handle_for_plane on plane 0 and fall back to old
non-planar method if the call fails. This removes the errno check (for
ENOSYS) that could abort if mesa ever sets a different value.

The function is intentionally provided as macro to not require a
cast. Recently the macro was improved to check that the passed in
pointer matches the free function, so the cast to GDestroyNotify
is now even harmful.

For historical reasons meta_monitor_is_active() checked whether it is
active by checking whether the main output have a CRTC assigned and
whether that CRTC has a current mode. At a later point, the MetaMonitor
got its own mode abstraction (MetaMonitorMode), but
meta_monitor_is_active() was never updated to use this.
An issue with checking the main output's CRTC state is that, if there is
some CRTC mode combination that for some reason isn't properly detected
by the MetaMonitorMode abstraction (e.g. some tiling configuration not
yet handled), meta_monitor_is_active() would return TRUE, even though no
(abstracted) mode was set. This would cause confusion here and there,
leading to NULL pointer dereferences due to the assumption that if a
monitor is active, it has an active mode.
Instead, change meta_monitor_is_active() to directly check the current
monitor mode, and log a warning if the main output still happen to have
a CRTC with a mode assigned to it. This way, when an not undrestood CRTC
mode combination is encountered, instead of dereferencing NULL pointers,
simply assume the monitor is not active, which means that it will not be
managed or rendered by mutter at all.

Avoid exporting through org.gnome.Mutter.DisplayConfig.GetCurrentState
excessively-low screen resolutions setting both a minimum width and a minimum
height. GetCurrentState is e.g. used by Gnome Control Center to build a list of
selectable resolutions.

If drmModeSetCrtc() is called with no fb, mode or connectors for some
CRTC it may still fail, and we should handle that gracefully instead of
assuming it failed to set a non-disabled state.

Add API to let GNOME Shell have the ability to get notified about remote
access sessions (remote desktop, remote control and screen cast), and
with a way to close them.
This is done by adding an abstraction above the remote desktop and
screen cast session objects, to avoid exposing their objects to outside
of mutter. Doing that would result in external parts holding references
to the objects, complicating their lifetimes. By using separate wrapper
objects, we avoid this issue all together.
Monitor whether UPower is running ourselves. That allows us to keep the
same value for "lid-is-closed" throughout the process of UPower
restarting, preventing unwanted monitor re-configuration through the process.
Fixes another screen black out when UPower restarts and the laptop lid
is closed.
Rather than handle UpClient in both MetaBackend (to reset the idletime
when the lid is opened), and in MetaMonitorManager and
MetaMonitorConfigManager (to turn the screen under the lid on/off
depending on its status), move the ability to get the lid status from
UPower or mock it in one place, in MetaBackend.
Restarting UPower will make every property of UpClient emit a "notify"
signal (as a GDBusProxy would). Avoid mutter reconfiguring the displays
when upower restarts by caching the last known value of "lid-is-closed"
and only reconfiguring the displays if it actually changed.
This fixes a black out of the screen when UPower restarts.
The framerate for screen cast sources was set to variable within 1 FPS
and the framerate of the monitor being screen casted. This meant that if
the sink didn't match the framerate (e.g. had a lower max framerate),
the formats would not match and a stream would not be established.
Allow letting the sink clamp the framerate range by setting it as
'unset', allowing it to be negotiated.
The PipeWire master branch saw some backports from the work branch,
including API changes making the 0.1 series more aligned with future
plans. Make mutter use the new API. This is needed to avoid dead locks
that existed in the older version.
Force update the cursor renderer after theme or size changes; otherwise
we'll be stuck with the old theme and/or size until something else

For some reason "backends: Remove X11 idle-monitor backend" removed
unrelated warning messages for when generated monitor configurations
that should work didn't, which also made the unit tests fail.
This commit adds them back, which also makes the tests pass again.
Commit 712ec30cd9 added the logic to only
choose EGL configs that match the GBM_FORMAT_XRGB8888 pixel format.
However, there won't be any EGL config satisfying such criteria for
non-GBM backends, such as EGLDevice.
This change will let us choose the first EGL config for the EGLDevice
backend, while still forcing GBM_FORMAT_XRGB8888 configs for the GBM
one.

Where to realize a hardware cursor depends on where on the screen it
will be displayed. For example it only needs buffers for the cursor
plane on a certain GPU if it overlaps with a monitor that is connected
said GPU.
Previously, we were too eager with uploading the cursor plane buffers,
which in effect resulted in the secondary GPU always being woken up
when changing the cursor, even though the cursor plane would actually
never be set unless the pointer cursor was moved to a monitor connected
to the secondary GPU. These wake-ups caused noticable stuttering; thus
by uploading the buffers more lazilly, the stuttering is avoided.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/77
When a cursor is hidden, the native backend will properly hide the HW
cursor sprite as well, but it would communicate this as if the cursor
was not handled by the backend, while in fact it still was. This caused
the generic cursor rendering layer to queue a redraw.

When force-updating the HW state we might end up with a situation where
the HW cursor is no longer usable. If this would happen, we'd before
this commit not trigger the fallback paths using a GL texture.
