gnome-desktop is used to retrieve the monitor vendor name which in some
use cases is not needed as it brings a bunch of gnome-desktop unwanted
dependencies.
The change makes mutter fallback to an "Undefined" vendor name if it is

Since the introduction of ClutterGrabs, MetaDnd now no longer gets
notified about input events on the stage during grabs (for example while
the alt-tab popup is shown) and thus can't move the grab feedback actor
anymore.
To fix this, forward events to MetaDnD directly from
meta_display_handle_event() when a ClutterGrab is in effect.

The XDG activation support was missing interoperability with other
startup sequences, notably those coming from other means than XDG
activation.
In order to play nice with X11 startup sequence IDs, we not just
have to check for the startup ID being in the general pool, but
we also need to fallback into X11-style timestamp comparison so the
window ends up properly focused.

When a drag and drop occurs from an X11 client to a Wayland native
client, mutter uses an internal X11 window as a peer for the DnD drop
site.
That internal X11 window is moved and resized to match the Wayland
native windows as the drag destination moves.
When moving from one Wayland native window to another Wayland native
window, the same X11 window is used, and as a result no DND enter/leave
events is emitted.
In that case, the drop may occur on the wrong Wayland native window,
because no new XdndEnter/XdndLeave event were emitted.
To avoid that issue, use a pair of X11 windows instead of just one and
alternate between the two when repicking a new drop surface, so that
moving from a Wayland surface to another will always generate the
expected enter/leave events that we rely on.

When generating the action label, we expect both directions of these
features to have consistent settings (either both get a keycombo, or
they don't) or these just return NULL altogether.
Since one of the directions has an action associated, this is
misleading, so be more lenient at the time of generating the action
label.

If we happen to handle a CLUTTER_TOUCH_BEGIN without a corresponding
CLUTTER_TOUCH_END at MetaWaylandTouch, we would still attempt to
reuse the older MetaWaylandTouchInfo, resulting in an assert triggered
as there is a stale touch reference on the previous surface.
Warn in place and create a new touch info struct to still fix the
broken surface accounting, instead of finding out the hard
way after the surface is destroyed. The assert is preserved to ensure
the accounting does not sneakily break anymore/further.

Even though it's great that XI2 has an event to notify about device

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
happily get a cursor renderer again.

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.

The `ensure_x11_unix_perms` function tries to detect systems on which
/tmp/.X11-unix is owned by neither root nor ourselves because in that
case the owner can take over the socket we create (symlink races are
fixed in linux 800179c9b8a1e796e441674776d11cd4c05d61d7). This should
not be possible in the first place and systems should come with some way
to ensure that's the case (systemd-tmpfiles, polyinstantiationm …). That
check however only works if we see the root user namespace which might
not be the case when running in e.g. toolbx.
This change relaxes the requirements such that in the root user
namespace we detect and abort if a vulnerable system is detected but
unconditionally run in toolbx.

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.

There may be situations where we may stack a ClutterGrab on top of a
wayland popup's. Since ClutterGrab should win over client grabs, we
mostly correctly figure out that it should start doing
bypass_wayland=TRUE and bypass_clutter=FALSE while the ClutterGrab
holds, however the late checks for the MetaDisplay event route can
still toggle bypass_clutter on, resulting in neither handling events.
This check for wayland popups in the display event route should just
enforce wayland handling if wayland is meant to be receiving events,
so ensure these don't mix together.

Wayland event processing and WM operations are themselves outside the
ClutterGrab loop so far. Until this is sorted out, these pieces of
event handling have got to learn to stay aside while there is a
ClutterGrab going on.
So, synchronize foci and other state when grabs come in or out, and
make it sure that Wayland event processing does not happen while
grabs happen.

Since we want these accessed from bindings this must be a boxed

The experimental feature "autoclose-xwayland" requires a couple of
prerequisites:
1. Be able to (re)start Xwayland on demand, i.e. with systemd
2. Xwayland must support the terminate delay

those prerequisites is not met.

Since commit 226afa24a - "Use Xwayland auto-terminate feature", the
callback function shutdown_xwayland_cb() does not check for the
autoclose-xwayland experimental feature anymore.
As a result, when running nested or outside of systemd,
gnome-shell/mutter would quit after 10 seconds unless some X11 window
was mapped.
But now that we rely on Xwayland's own terminate feature, there really is
no need to use any xserver timeout function anymore.
We do not need to keep track of X11 windows being created or unmapped, as
again, Xwayland does all that for us at the client level.
Remove all this code that we do not need anymore.
fixes: 226afa24a - Use Xwayland auto-terminate feature
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2258>
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).

When using Xwayland-on-demand (default), if the (experimental) autoclose
features is enabled, we can rely on Xwayland's auto-terminate feature
instead of explicitly killing the Xwayland process.
With it, gone is the mechanism that was added to check the X11 clients
connected and their executable to check whether we can (safely) kill
Xwayland.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1794>
The connection to the Xserver for the X11 window manager part of mutter
even on Wayland may prevent the Xserver from shutting down.
Currently, what mutter does is to check the X11 clients still connected
to Xwayland using the XRes extension, with a list of X11 clients that
can be safely ignored (typically the GNOME XSettings daemon, the IBus
daemon, pulseaudio and even mutter window manager itself).
When there is just those known clients remaining, mutter would kill
Xwayland automatically.
But that's racy, because between the time mutter checks with Xwayland
the remaining clients and the time it actually kills the process, a new
X11 client might have come along and won't be able to connect to
Xwayland that mutter is just about to kill.
Because of that, the feature “autoclose-xwayland” is marked as an
experimental feature in mutter and not enabled by default.
Thankfully, the Xserver has all it takes to manage that already, and
is even capable of terminating itself once all X11 clients are gone (the
-terminate option on the command line).
With XFixes version 6, the X11 clients can declare themselves
"terminatable", so that the Xserver could simply ignore those X11
clients when checking the remaining clients and terminate itself
automatically.
Use that mechanism to declare mutter's own connection to the Xserver as
"terminatable" when Xwayland is started on demand so that it won't hold
Xwayland alive for the sole purpose of mutter itself.

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
condition would evaluate to true, which is rather unexpected.
Fix this by making sure the string length is correct first. Also move it
into a helper so we don't need to repeat the same strlen() check every
time.
