On hotplug, the events we receive from the kernel are async, and
connectors in the kernel come and go as they please. In practice, this
means that calling drmModeGetConnector() twice more or less directly
after each other, there is no guarantee that the latter call will return
anything if the former did.
When updating the connector in response to hotplugs, we'd first update
the list of existing connectors, and following that, query each and
every one again for their current state, to update our internal
representation; only the former handled drmModeGetConnector() returning
NULL, meaning if unlucky, we'd end up doing a null pointer dereference
when trying to update the state.
Handle this by querying the kernel for the current connector state only
once per connector, updating the list of connectors and their
corresponding state at the same time.
Fixes the following crash:

We can land inside meta_window_focus() in the middle of changing the
window workspace, because some signal handler of MetaWorkspace's
"window-removed" signal triggers a focus. This can cause a crash in
`g_assert (link)` when updating the MRU list because we still think
we're on the old workspace when actually we are already removed from
this workspaces MRU list.
To avoid crashes like this, bail out of meta_window_focus() when we're

It is generally assumed here and there that the pointer at all point in
time is within some logical monitor, if there is any logical monitor to
be within.
With the input thread, this was for a short amount of time not reliable,
resulting in crashes in combination with hotplugging or suspend/resume,
where monitors come and go quickly.
What happens is that the pointer at first is within a logical monitor,
but when that logical monitor is removed, while the new monitor
viewports are handed to the input thread, the constraining happens
asynchronously, meaning there is a time between between the new
viewports are sent, and before clutter_seat_query_state() starts
reporting the constrained position.
If a new client mapped a maximized window during this short time frame,
we'd crash with

after the input thread is done constraining before continuing.

Currently, we will notify the display about a new window being created

property-change notifications are frozen by GObject, so we'll emit a few

The CRTC cursor sprite scale was incorrectly assumed to be always 1.0
when using the default not-scale-monitor-framebuffer mode. This is
harmless in most cases, as most clients provide HiDPI capable cursors,

unscaled, when using the cursor planes.

Cursor planes tend to be ARGB8888 and support no other format (ideally
we should not hard code this, but un-hard-coding that is for another
day), and if we put e.g. a XRGB8888 buffer in there, it'll either result
in the gbm_bo allocation failing (it doesn't allow USE_CURSOR with any
other format) or mode setting failing if using dumb buffers directly.
In the former case, we'll fall back to OpenGL indefinitely, and in the
latter, we'll have failed mode sets as long as we try to set the invalid
cursor buffer as the cursor plane.
Change things to process all buffers that are not ARGB8888 using the
scale/rotate machinery we already have, turning XRGB8888 into ARGB8888.

A client may provide a positioner that places the window outside of its
parent. This isn't allowed, according to spec, so we hide the window and
log a warning. This, however, leads these affected clients with an
incorrect view of what is mapped or not, meaning it becomes harder to
recover.
Fix this by sending xdg_popup.done when we hide the popup due to an
invalid position. Don't error out the client, let the bug slide, as
that's a less jarring experience for existing applications that
reproduce this than being disconnected, which practically feels like a

In constrast to x11, Wayland has sane handling for touch events and
allows the compositor to handle a touch event while the clients are

them.

Back in 2014 sending pressed keys to Wayland clients caused issues,
because at least Xwayland didn't handle that gracefully, causing issues
like ghost-pressed keys. A way it was reproduced was quickly alt-tab:ing
to and from a Firefox window, which would cause the File menu bar
incorrectly appearing.
While this was reported to the Xwayland component back then, it was,
probably by mistake, assumed to be an issue in mutter, and mutter
stopped sending pressed key events on enter.
The following year, Xwayland was eventually fixed, but the work around
in mutter has been kept around until it was again noticed as an
inconsistency between compositor implementations.

With high frequency mouse devices, we would send very many configure
events per each update cycle, which had the end result that some clients
constantly re-allocating and redrawing their buffers far too often, if
they did this in direct response to xdg_toplevel configure events.
Lets throttle the interactive resize updates to stage updates, to avoid
having these clients doing the excessive buffer reallocation.
This also removes some old legacy X11 client resize throttling, that
throttled a bit arbitrarily on 25 resizes a second; it is probably
enough to throttle on stage updates for these clients.

Some mice send a value slightly lower than 120 for some detents. The

detent detent
| | |
^ ^ ^
112 REL_WHEEL 224
As illustrated, only one event was sent but two were expected. However,
sending the low-resolution scroll event in the middle plus the existing
heuristics to reset the accumulator solve this issue:

In fcfe90aa, multiple for loops were replaced with
META_WAYLAND_SURFACE_FOREACH_SUBSURFACE.
However, this substitution was not side-effect free, and introduced a
null-pointer dereference risk as shown in the example below:
Old:
for (n = g_node_first_child (surface->subsurface_branch_node);
n;
n = g_node_next_sibling (n))
{
if (G_NODE_IS_LEAF (n))
continue;
meta_wayland_surface_update_outputs_recursively (n->data);
}
n is checked for NULL during each loop in the condition expression.
Therefore, when `G_NODE_IS_LEAF (n)` is called, `n` is guaranteed not to
be NULL. Note also that g_node_first_child is also NULL-safe since it
performs a NULL check internally.
New:
META_WAYLAND_SURFACE_FOREACH_SUBSURFACE (surface, subsurface_surface)
meta_wayland_surface_update_outputs_recursively (subsurface_surface);
=
for (GNode *G_PASTE(__n, __LINE__) = meta_get_first_subsurface_node ((surface)); \
(subsurface = (G_PASTE (__n, __LINE__) ? G_PASTE (__n, __LINE__)->data : NULL)); \
G_PASTE (__n, __LINE__) = meta_get_next_subsurface_sibling (G_PASTE (__n, __LINE__)))
In the new logic `subsurface` is still checked for NULL in the loop
condition. However, in the new loop init:
...
meta_get_first_subsurface_node (MetaWaylandSurface *surface)
...
n = g_node_first_child (surface->subsurface_branch_node);
if (!G_NODE_IS_LEAF (n))
...
The above implementation performs a `G_NODE_IS_LEAF` call, which
performs a dereference on `n`, without first checking for NULLs.
This NULL dereference triggers the following gnome-shell crash:
Core was generated by `/usr/bin/gnome-shell'.

Fullscreen Wayland toplevel surfaces don't need to respect the

Fullscreen Wayland toplevel surfaces don't need to respect the
configured size in which case it should be shown centered on the monitor
with a black background. The black background becomes part of the window
geometry.
The surface container is responsible for correctly culling the surfaces
and making sure the surface actors are removed from the actor tree to
avoid destroying them.
The window actor culling implementation assumes all surfaces to be direct
children of said actor. The introduction of the surface_container actor
broke that assumption. This implements the culling interface in
MetaWindowActorWayland which is aware of the actor surface_container and
fullscreen state.

A "window rect" in most places refers to the rectangle the window
corresponds to when it comes to window management. MetaWindow::rect also

When a window configuration is constructed for a Wayland surface it
contains a position, size and a scale. The scale is the geometry scale
for the configuration, i.e. before the size is sent the passed dimension
is divided with the passed scale.
When moving between monitors with different scales, if we use the
existing geometry scale, this means we will send a configure event with
incorrect dimensions. Fix this by calculating the scale used in the
configuration given the rect we're configuring with as this will mean
the correct size will be sent to the client.

We want to use the workspace MRU list to decide the default focus but
Globally Active Input clients don't call
meta_window_set_focused_internal and therefore don't update the MRU
list. Move the update to meta_window_focus instead.

The completed signal is only emitted if the timeline actually completed
but when an actor is destroyed or removed from its parent the timeline
is stopped and not completed.
The workspace switch effect removes window actors from the window group
which destroys the timeline so on_$EFFECT_effect_stopped is never
called and the pointer to the timeline is dangling.

The workspace switch animation moves the WindowActors out of the
WindowGroup so if we shut down while the animation is playing the
WindowActors will have queued a destroy but will be disposed only after
the compositor is destroyed, leaving the WindowActor with a dangling
pointer.
Fix the issue by killing the workspace switch animation on shutdown.

This is an old relic from when ClutterStageView was being added, and
tests were somewhat prepared to be able to test the "X11 style" of
things, with the nested backend some how managing to emulate that.
Lets drop that stuff, it isn't used by the test suite, and isn't useful
anyway; if we want to test X11 configurations, we should use the actual
X11 backend, which didn't make use of this anyway.

This adds a copy of the calibration test profile and sets up a test to
first add it as a system profile, then setting up the XDG_DATA_HOME

We might fail with some part of the color profile construction and
initialization. For example there might be a system wide profile with
the same ID as one we attempt to add from a local ICC directory. When
this happens, we should drop these profiles, and use the ones from the
system instead.
Profiles may fail to initialize for other reasons too, e.g.
unpredictable colord errors, or other I/O issues.

If our profile wasn't fully initialized, we'd try to clean it up, in an
attempt to handle race conditions by finding synchronously then cleaning
it up, but don't attempt this if the profile is ready, as that means we

This is instead of getting anything from the CdDevice. This avoids a
crash when CdDevice isn't successfully setup but something still tries
to look up the filename of the ICC profile.
This isn't a real bug fix for anything, but there is no reason having to
rely on CdDevice for this anyway, and as we don't really have control of
it, it's less reliable of containing something valid.

When creating a render device, we create a temporary EGLContext where we
then query the `GL_RENDERER` string to check whether the renderer is any
of the known software renderers. After we're done, we destroy the
context and move on.
This should be fine as according to specification eglDestroyContext(),
with the context being actually destroyed a bit later when it's no
longer current, but mesa, when running RK3399 (Pinebook Pro), this
results in a crash in a future eglMakeCurrent():
#0 in dri_unbind_context () at ../src/gallium/frontends/dri/dri_context.c:266
#1 in driUnbindContext () at ../src/gallium/frontends/dri/dri_util.c:763
#2 in dri2_make_current () at ../src/egl/drivers/dri2/egl_dri2.c:1814
#3 in eglMakeCurrent () at ../src/egl/main/eglapi.c:907
...
We can avoid this, however, by calling eglMakeCurrent() with
EGL_NO_CONTEXT on the EGLDisplay, prior to destroying, effectively
avoiding the crash, so lets do that.

We'll never scan out, which is why ADDFB2 is required otherwise, and we

EGLStream is incompatible with atomic mode setting, but nvidia-drm when
using libgbm is not, so lets only deny using atomic mode setting when
the render device is an EGLStream based one.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2578>
The type of render device used for a specific GPU affects the mode
setting backend that can be used, more specifically, when the render
device is an EGLStream based one, atomic mode setting isn't possible, as
page flipping is done via EGL, not via atomic mode setting commits.
Preparing the render devices before KMS devices means can make a more
informed decision whether to deny-list atomic mode setting for when
a certain GPU uses a EGLStream based render device instance.
This also means we need to translate mode setting devices to render node
devices when creating the render device itself, as doing it later when
creating the mode setting device is already too late.

Currently, the peripheral "output" setting will be unset if Mutter is
deciding automatically the mapped output of a tablet device. In that
case, gnome-control-center will have a hard time figuring out itself
the better output to show the tablet calibration UI, unless it's hand
held by Mutter.
Add this private D-Bus interface so that gnome-control-center can look
up the output as determined by Mutter to bring the missing harmony
between both. This interface consists of a simple method to get the
mapped output for a input device node.

The D-Bus runner used by tests, including installed tests, is made to be
reusable from GNOME Shell. To do this, install it and the templates in
the pkgdatadir (e.g. /usr/share/mutter-APIVERSION/tests/), generate a
custom runner for the installed tests that uses the installed script and
templates, and change the non-installed original runner to use the
non-installed templates.
The end goal is to reuse the D-Bus session runner and templates used for
mutter when test running GNOME Shell.

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 initialize swap_region earlier, before appending the
damage history.
This may help optimizing the composition process in some cases (at least
on X11 when EGL_KHR_swap_buffers_with_damage is available) by not
accumulating additional regions as damaged unnecessarily.

This is what the protocol says we should do, and even though normally
an out of focus client should not have any reason to create IM requests,
there is a bit of a grey area around focus changes, as both the client
losing focus and the client gaining focus may respectively try to
disable/enable in an undetermined order.
Anyways, since in that situation the client losing focus is not aware
of the requests being ignored, the serial should always be incremented
in order not to break accounting of .done/.commit for that specific
client.
Fixes the IM focus being possibly "lost" after changing focus between
clients, if the race condition turned the odds in that direction.

Mutter can play sounds in some contexts and also provides an API
for libmutter users to do so using libcanberra internally.
In some specific use cases of Mutter, we would like to not depend
on libcanberra and not have any sound playing feature by default.
The changes keeps the sound player API but make it no-op if the

This allows using two separate ICC profiles for one "color profile",
which is necessary to properly support color transform
calibration profiles from an EFI variable.
These types of profiles are intended to be applied using the color
transformation matrix (CTM) property on the output, which makes the
presented output match sRGB. In order to avoid color profile aware
clients making the wrong assumption, we must set the profile exposed
externally to be what is the expected perceived result, i.e. sRGB, while
still applying CTM from the real ICC profile.
The separation is done by introducing a MetaColorCalibration struct,
that is filled with relevant data. For profiles coming from EFI, a
created profile is practically an sRGB one, but the calibration data
comes from EFI, while for other profiles, the calibration data and the
ICC profile itself come from the same source.

We may want to use scanout even if the default framebuffer
of the stage view is an offscreen, for example when a Wayland
client provides pre-rotated buffers. The caller is responsible
to ensure this is correct - we already asserted on that before.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2468>
If a stage view uses an offscreen framebuffer exclusively for
rotation and a Wayland client provides pre-rotated buffers,
we should try to use scanout.
This saves us one copy more than scanout in the onscreen case,
i.e. two fullscreen copies in total.
Offscreen rotation is notably used for all 90/270 degree rotations
at the moment, as using display hardware for them is apparently
more complex than for x-/y-flips and can even have detrimental
effects on power consumption.
This can be tested with `weston-simple-egl`.

This mocks gsd-colord to enable night ligth at a given temperature. The
test then verifies that the result exactly matches that of the gamma
ramps gsd-color generated for the same temperature and ICC profile.
There are two types of profiles tested; ones with VCGT, i.e. calibrated
profiles, and ones without. These are tested as the VCGT affects how the
gamma curve looks, while the non-VCGT profiles all only rely on
the blackbody temperature to generate a gamma ramp.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2165>
More or less copied from gnome-settings-daemon. The look up tables are
either calculated based on the VCGT (Video Card Gamma Table) and the
blackbody color for a given temperature, or the blackbody color for a
given temperature alone, if no VCGT is available.

This means that e.g. custom profiles or calibrated profiles will be
added and registered with colord. This does not use CdIccStore for two
reasons: don't want to generate duplicate entries for auto-generated
EDID or EFI profiles, and we want to store profiles as MetaColorProfile.
It also happens to be the case that CdIcc does synchronous I/O, which
should be avoided everywhere except on startup.

Instead of passing 4 arguments (red, green and blue arrays as well as a
size), always pass them together in a new struct MetaGammaLut. Makes
things slightly less tedious.
The KMS layer still has its own variant, but lets leave it as that for
now, to keep the KMS layer "below" the cross backend CRTC layer.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2165>
In practice, for KMS backend CRTC's, we cache the gamma in the monitor
manager instance, so that anyone asking gets the pending or up to date
value, instead of the potentially not up to date value if one queries
after gamma was scheduled to be updated, and before it was actually
updated.
While this is true, lets still move the API to the MetaCrtc type; the
backend specific implementation can still look up cached values from the
MetaMonitorManager, but for users, it becomes less cumbersome to not
have to go via the monitor manager.

We created device profiles, that we manage the lifetime of in colord,
but color devices can be assigned profiles other than the ones it was
created for. For example, this can include the standard sRGB profile
provided by colord.
To achieve this, keep track of the default profile of the CdDevice as
the "assigned" color profile of the device. Given this profile
(CdProfile), construct a MetaColorProfile that can then be interacted
with as if it was generated by ourself.
The assigned profile (default profile in colord terms) does nothing
special so far, but will later be used to determine how to apply CRTC
gamma ramps etc.
The sRGB.icc file used in the tests was copied from colord. It was
stated in the repository that it has no known copyright restrictions.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
This works similiarly to how MetaColorDevice works, by creating them
asynchronously then signalling the 'ready' signal when done. Also
similarly to MetaColorDevice, the on-demand sync cleanup on finalize is
added, to avoid race conditions when hotplugs happens very rapidly,
e.g. in tests.

Just as gsd-color does, generate color profiles. This can either be done
from EFI, if available and the color device is associated with a built
in panel, or from the EDID. If no source for a profile is found, none is
created.
The ICC profiles are also stored on disk so that they can be read by
e.g. colord. The on disk stored profiles will only be used for storing,
not reading the profiles, as the autogenerated ones will no matter what
always be loaded to verify the on disk profiles are up to date. If a on
disk profile is not, it will be replaced. This is so that fixes or
improvements to the profile generation will be made available despite
having run an older version earlier.
After generating, add some metadata about the generated file itself
needed by colord, i.e. file MD5 checksum and the file path.

gsd-color provides this API, which exposes details about the night light
state. Currently, gsd-color also turns this state into CRTC gamma
changes, but this will eventually change, and this is a preparation for
this.
The proxy isn't yet used for anything.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
Previously, gsd-color handled adding color devices. It got information
about those via the GnomeRR API, which is part of libgnome-desktop.
libgnome-desktop itself got this information from the
org.gnome.Mutter.DisplayConfig.GetResources() D-Bus method, implemented
by mutter.
Now, mutter itself will add all the monitor color devices itself,
without having to go via gsd-color.
We sometimes need to delete colord devices synchronously, in certain
race conditions when we add and remove devices very quickly (e.g. in
tests). However, we cannot use libcolord's 'sync' API variants, as it
has a nested takes-all main loop as a way to invoke the sync call. This
effectively means we end up sometimes not return from this function in a
timely manner, causing wierd issues.
Instead, create our own sync helper, that uses a separate context that
we temporarly push as the thread-default one.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2141>
This will be needed for adding colord integration without breaking
testing.
The test context is altered to make sure any left over color devices are
cleaned up before starting. This means it becomes possible to run a test
case multiple times without having to restart meta-dbus-runner.py.
Note: Don't use os.getlogin() to get the current username; as that
requires a controlling terminal.

What determines whether one MetaMonitor is the same as the other should
be whether the actual monitor is the same. The way to check this is
comparing the EDID vendor/product/serial fields. Whene these are
incomplete, fall back on the 'winsys ID'.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2141>
Same applies to MetaOutput. The reason for this is to make it possible
to more reliably know when there was EDID telling us about these
details. This will be used for colord integration.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2141>
We fairly consistently had multiple monitors with the whole
vendor,product,serial tuple identical. If we start relying on making
monitors a bit more unique, e.g. for colord integration, we need to make
two monitors connected distinguishable in order for tests to properly
reflect reality and excercise the correct colord integration paths.

As for the types of monitor, X11 and KMS are currently assumed to always be
physical, while the virtual ones are assumed to be virtual. In theory
X11 ones could be virtual, but lets not bother. KMS ones can be virtual
in the case of virtual KMS, but we typically use that for testing as if
it was physical, so lets leave it as such.
Will later be used to feed correct information to colord.

This reverts an attempt at saving texture memory that was introduced
recently in 16fa2100. It was misguided because the same texture may be

The "activate" and "deactivate" signals on ClutterStage are used by
Cally to track the key-focus when the user is interacting with shell UI.
key-focus only gets tracked while the stage is activated.
Wayland has no concept of the stage receiving focus or not, so right now
the activation state is bound to whether there's a focus_window in
meta_display_sync_wayland_input_focus(). Since display->focus_window is
set pretty much all the time, this effectively binds activation state to
whether the stage holds a grab or not. This is almost good enough, but
it misses cases where key-focus is on the stage without a grab, for
example when keyboard-navigating the panel after using Ctrl+Alt+Tab.
It seems to make more sense to bind the activation state to whether
key-focus is set to an actor or to NULL, so let's do that instead.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2329>
In the timespan between an activation token being created and the
token being used by the activated application, the surface that started
the activation request may end up destroyed/disposed.
In that case, the token would be left with a stale surface pointer,
maybe causing crashes later on. Set up a destroy notification listener
so that we do know to unset the token surface if that situation arises,
this will result in Mutter not considering the token activatable, thus
maybe issuing the "Application needs attention" notification if the
activated surface did not immediately get focus. In any case this is
better than a compositor crash.
A typical situation where this may happen is "Open With..." dialogs,
since those don't live long after launching the application.
Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/2390
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2592>
There is some surface tracking going on here, and all notify handlers

Since commit 1bf70334 "tests/runner: Make test runner use the headless

will attempt to open each GPU and show a warning (fatal during tests)

However, in headless mode we might not be logged in on any seat (for
example we might be logged in via ssh instead), which means we might
legitimately not have permission to use any GPUs, even if they exist.

When we e.g. generate switch configs (i.e. the ones from pressing the

"good" monitor scale.
With "good", it means pick a scale that was used in a previous
configuration. In practice, this means that if you for example have
configured your external monitor to use a specific scale, then pressed
e.g. "built in only", and then switched back to e.g. "external only" or
"linear", the generated configuration will use the scale that was

If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.
This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.

This will eventually help with better hueristics for finding a good
scale. It currently doesn't change much, but the helper will later gain
more functionality that will also help when coming up with mirroring
configs.

The resulting logical monitor was eventually marked as primary anyway,
but without the config being marked as such, various primary properties
was not set e.g. the one on the MetaOutput. Also, tests would fail.

This condition is inverted of how it should be. Since pad focus relies
on grouped devices lookups (e.g. pads not grouped with a tablet do not
focus surfaces), this fixes issues in pad focus and event propagation to
wayland clients.

This checks that an unmapped but created Wayland window correctly handle
monitor changes. This is specifically added to test an edge case causing
a crash with the following backtrace:

If the window didn't have a size, it would still have a monitor, and
when we are asked to update, we must update, as the old monitor might
not be kept around, leaving us vulnerable to use after free.
Avoid not updating the monitor by using the stored IDs (preferred, or
previous) to find suitable logical monitors, with the primary monitor
being the last fallback unless we're completely headless.
This fixes the assert
!window->monitor ||
g_list_find (meta_monitor_manager_get_logical_monitors (monitor_manager),
window->monitor)
in meta_window_update_for_monitors_changed() being hit when a Wayland
window has been created, but not mapped, when a hotplug happens.

The function finds a suitable logical monitor given the window
rectangle; this wasn't all that clear from the name
"calculate_main_logical_monitor".
This is in preparation for finding a new logical monitor using things
other than the geometry of the window.

This will allow tests to change monitor resolution. The first argument
is the monitor ID; there is always one monitor added by default, and it
has the id 0. It's currently not possible to add more monitors, so
passing '0' is the only valid way to resize monitors.

This hasn't worked for a while, since the test always runs the nested
backend, meaning it's a Wayland compositor. To unblock testing window
management in combination to monitor changes, lets remove the
unreachable X11 WM paths, so that we can start using virtual monitors.

util-private.h includes glib-i18n-lib.h, which requires GETTEXT_PACKAGE
to be defined. The define comes from config.h,
but that cannot be included in headers, so we have to make sure
that any source file that pulls in util-private.h (or a header
that includes it) includes config.h first.

mutter needs GDK to use the x11 backend. It already calls
gdk_set_allowed_backends ("x11") for this purpose; however, if
GDK_BACKEND=wayland (or any other non-x11 backend possibly) happened to
be in the environment, GDK would fail to initialize at all. This would
result in mutter not registering as X11 window manager, and all X11
clients hanging.
Big thanks to Olivier Fourdan for figuring this out!
v2:
* Restore original value of GDK_BACKEND environment variable after
initializing GDK.

It consists of only a macro and build description logic.
Adds a macro for simpler tests that doesn't require a context; unit
tests requiring a context should use the same framework as conform
tests.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2555>
All working tests have already migrated to the test suite using mutter;
move the old unported tests over too, and remove the conform test
framework, as it is no longer used.
