ce25a0171c monitor-unit-tests: Add test for lid closed after hot plug
Add a test case that checks that we don't try to revert to a
laptop-panel-only configuration after closing the lid after an external
monitor is connected.

b7518c8651 monitor-manager: Compare keys when checking whether a config is complete
We only counted configured monitors and whether the config was
applicable (could be assigned), howeverwe didn't include disabled
monitors when comparing. This could caused incorrect configurations to
be applied when trying to use the previous configuration.

One scenario where this happened was one a system with one laptop
screen and one external monitor that was hot plugged some point after
start up. When the laptop lid was closed, the 'previous configuration'
being the configuration where only the laptop panel was enabled, passed
'is-complete' check as the number of configured monitors were correct,
and the configuration was applicable.

Avoid this issue by simply comparing the configuration key of the
previous configuration and the configuration key of the current state.
This correctly identifies a laptop panel with the lid closed as
inaccessible, thus doesn't incorrectly revert to the previous
configuration.

62dedfbef3 monitor-config-manager: Don't include closed laptop panel in config key
When deriving the list of disabled monitors when creating new monitors
configs, don't include the laptop panel if the lid is currently closed,
as we consider the laptop panel nonexistent when the laptop lid is
closed when it comes to configuration.

The laptop panel connector(s) will either way be appropriately disabled
anyway, as the field listing disabled monitors in the configuration do
not affect actual CRTC/connector assignments.

4508978ea5 wayland/xdg-shell: Dismiss a popup on map if parent already dismissed
If a parent doesn't have a window, it means it could have been
dismissed (for example due to a input serial race), but the more recent
popup might win the input serial race and try to map anyway. This would
result in a crash later on when trying to process the placement rule,
as the parent already has no window.

5d3b4f0134 wayland/xdg-shell: Fix top-most check when grabbing
Move the top-most-popup correctness check to the finish_popup_setup()
function after checking the serial. If we pass the serial check, we
should have reached a state that if there are any popups they should be
the one from the same client.

Also avoid failing a client that correctly set the top-most popup at map
time, but where at the time of processing the top most popup have
already been dismissed by the compositor for some arbitrary reason.

3067dab84c backends: Do not set up the root cursor on invisible window pointers
Commit b1a0bf891 broke the previous logic that we would only fallback
to the root cursor if 1) windows are not interactable or 2) no window
cursor is currently set (i.e. not hovering over any window). Now it
will set up the root cursor if it's NULL, which breaks clients
explicitly setting an invisible cursor. This commit restaurates the
previous behavior.

1790320ba3 backends: Protect from reentrancy in meta_cursor_sprite_load_from_theme
This function is supposedly not failable, so just move the theme_dirty
flag clearing to the beginning of the function. Protects against cases
where requesting a cursor image may result in it being loaded and set
as a texture, which emits ::texture-changed, which may end up requesting
the cursor image again.

bcbcd6a68c backends: Add MetaCursorSprite::texture-changed signal
As wayland implements the cursor role, it consists of a persistent
MetaCursorSprite that gets the backing texture changed. This is
inconvenient for the places using MetaCursorTracker to track cursor
changes, as they actually track MetaCursorSprites.

This signal will be used to trigger emission of
MetaCursorTracker::cursor-changed, which will make users able to
update accordingly.

b1a0bf8916 backends: Dissociate visibility from current cursor sprite
Just like X11/XFixes behaves, the current cursor is not affected
by its visibility, so it can be queried while invisible (possibly
to be replaced).

For this, keep an extra effective_cursor pointer that will be
either equal to displayed_cursor (maybe a bit of a misnomer now)
or NULL if the cursor is invisible. The MetaCursorRenderer
management is tied to the former, and the ::cursor-changed signal
emission to the latter.

3ee1999c70 backend: Reset current device id when current device removed
Bluetooth mouse usually goes in sleep state after a timeout, when that
happen the mouse is disconnected and on_device_removed function is
called. Before the patch if a touch device is available the
on_device_removed function hide the cursor. The issue is that the cursor
does not reappear once the bluetooth mouse is reconnected because
MetaBackend::current_device_id is not invalidated when on_device_removed
was called.

The patch set MetaBackend::current_device_id to 0 if the current device
is removed. This will make update_last_device to be triggered as soon as
another input device is used or the bluetooth mouse reconnect, as
consequence that the cursor reappear. The id 0 is never given to devices
and can safely used as undefine id.

b6200ac3ff wayland/keyboard: Don't transfer layout group when replacing xkb state
The layout group determines what actual keyboard layout in the keymap
to use when translating modifier state and key codes to key syms.
When changing a keymap to another, the layout groups has no relation to
the layout groups in the old keymap, thus there is no reason to
transfer it to the new state.

This fixes an issue where the xkb state in meta-wayland-keyboard.c got
desynchronized with the xkb state in clutter-device-manager-evdev.c.

Both signals are necessary in order to cater for toplevel and subsurface

Also, shuffle signal disconnection, so each signal goes away with

In such scenario a MetaWindow could try to start a simple effect

conditions are valid, so that gnome-shell will provide a dumpstack to

Do this by iterating through all the monitors adding all supported
scales by the preferred mode, combining all the supported scales. This

6eb7d13894 window: Handle updating from no to no monitor
When we received two hot plug events that both resulted in headless
configuration, we tried to find a new window monitor given the old.
That resulted in a null pointer dereference; avoid that by only trying
to find the same monitor if there was an old one.

78e6258b44 cursor-renderer-native: Support HW cursors on multiple GPUs
On hybrid GPU systems, hardware cursors needs to be realized on all the
GPUs, as scanout cursor planes cannot be shared. Do this by moving gbm
buffer and drm buffer ID management to a per GPU struct, realizing a
cursor on each GPU when previously only realized on the primary GPU.

c9259c2b15 renderer-native: Add hybrid GPU system support
A hybrid GPU system is a system where more than one GPU is connected to
connectors. A common configuration is having a integrated GPU (iGPU)
connected to a laptop panel, and a dedicated GPU (dGPU) connected to
one or more external connector (such as HDMI).

This commit adds support for rendering the compositor stage using the
iGPU, then copying the framebuffer content onto a secondary framebuffer
that will be page flipped on the CRTC of the dGPU.

This can work in two different ways: GPU accelerated using Open GL ES
3, or CPU unaccelerated.

When supported, GPU accelerated copying works by exporting the iGPU
onscreen framebuffer as a DMA-BUF, importing it as a texture on a
separate dGPU EGL context, then using glBlitFramebuffer(), blitting it
onto a framebuffer on the dGPU that can then be page flipped on the dGPU
CRTC.

When GPU acceleration is not available, copying works by creating two
dumb buffers, and each frame glReadPixels() from the iGPU EGL render
context directly into the dumb buffer. The dumb buffer is then page
flipped on the dGPU CRTC.

the GPU is abstracted by the X server; only the native backend (aside
from the test backend) will eventually see more than one GPU.

a5f4ffa58c window: Track edge constraints
GTK has the ability to handle client-decorated windows
in such a way that the behavior of these windows must
match the behavior of the current window manager.

In Mutter, windows can be tiled horizontally (and, in
the future, vertically as well), which comes with a few
requirements that the toolkit must supply. Tiled windows
have their borders' behavior changed depending on the
tiled position, and the toolkit must be aware of this
information in order to properly match the window manager
behavior.

In order to provide toolkits with more precise and general
data regarding resizable and constrained edges, this patch
makes MetaWindow track its own edge constraints.

This will later be used by the backends to send information
to the toolkit.

a1c39e142d window: Also consider touching edges for matching tiled windows
When computing a potential match for a tiled window, there is a
chance we face the case where 2 windows really complement each
other's tile mode (i.e. left and right) but they have different
sizes, and their borders don't really touch each other.

In that case, the current code would mistakenly assume they're
tile matches, and would resize them with either a hole or an
overlapping area between windows. This is clearly a misbehavior
that is a consequence of the previous assumptions pre-resizable
tiles.

This patch adapts the tile match algorithm to also consider the
touching edges when computing the matching tile, unless:

 * the window is not currently tiled (for example when computing
   the tile preview)
 * the window is currently resized in tandem with an existing
   tile match

e76a0f564c window: Raise and lower tile match in tandem
When a pair of tiled windows are grouped together, they
are treated as parts of a whole and interacting with one
affects the other.

Following the idea that sibling tiled windows are treated
as part of the same group, they should also be raised and
lowered together.

It is still possible to break tiled windows grouping by
simply untiling the window with the keyboard or by grabbing
and resizing or moving the window with the cursor.

This patch makes sibling tiled windows be lowered and raised
in tandem. For future reference, this behavior is documented
in [1].

These snapping sections are not really tied to any other
window, and only depend on the current work area of the
window. Thus, it is not necessary to adapt the current
snapping edge detection algorithm.

This patch adds the necessary code in edge-resistance.c
to special-case tiled windows and allow them to cover
1/4, 1/3 and 1/2 (horizontally) of the screen. These
values are hardcoded.

6fe71ecc01 window: Tile and resize considering the tile match
After the introduction of the possibility to resize tiled windows,
it is a sensible decision to make windows aware of their tiling
match. A tiling match is another window that is tiled in such a
way that is the complement of the current window.

The newly introduced behavior attepts to make tiling as smooth as
possible, with the following rules:

 * Windows now compute their tile match when tiling and, if there's
   a match, they automatically complement the sibling's width.
 * Resizing a window with a sibling automatically resizes the sibling
   too to be the complement of the window's width.
 * It is not possible to resize below windows' minimum widths.

57e58eaf2a window: Maximize tiled windows when resizing to work area
Now that tiled windows are resizable, the user may grow a tiled

subtle differences by properly maximizing the window in that case.

00a5db71cf window: Allow resizing of tiled windows
Currently tiled windows are not resizable and their size is fixed
to half the screen width. Adjust the code to work with fractions
other than half, and allow users to adjust the split by dragging
the window edge that is not constrained by a monitor edge.

Follow-up patches will improve on that by resizing neighboring
tiled windows by a shared edge, and making the functionality
available to client-side decorated windows implementing the
new edge constraints protocol.

c7fa57cd28 window: Pass mode as parameter to tile() operation
Now that the preview tile mode has been split from the window's

8f2c86d79e window: Split out preview_tile_mode
The existing semantics of the tile_mode property are terribly confusing,
as it depends on some other property whether it represents the requested
or current mode. Clear this up by just using separate variables for the
two. As it is unlikely that we will ever support more than one tile
preview, we can track the requested mode globally instead of adding
another per-window variable.

9c16e4e2f3 wayland: Keep the inhibit shortcut dialog
On Wayland, the grab()/ungrab() in gtk+/gdk are wired to the shortcut
inhibitor mechanism, which in turn shows the dialog, which can take
focus away from the client window when the dialog is shown.

If the client issues an ungrab() when the keyboard focus is lost, we
would hide the dialog, causing the keyboard focus to be returned to the
client surface, which in turn would issue a new grab(), so forth and so
on, causing a continuous show/hide of the shortcut inhibitor dialog.

To avoid this issue, keep the dialog around even if the shortcut inhibit
is canceled by the client, so that the user is forced to make a choice
that we can reuse on the next request without showing the dialog again.

Instead of hiding the dialog when the shortcut inhibitor is destroyed by
the client, we simply mark the request as canceled and do not apply the
user's choice.

522eec00cd monitor: Add foreach output helper and fix foreach crtc helper
The foreach CRTC monitor mode helper incorrectly iterated over outputs
without CRTC when non-tiled modes were set on tiled monitors. This was
not expected by callers, so fix the helper to only iterate over active
outputs (that has or should have a CRTC).

The test cases uses the incorrect behaviour of the foreach CRTC helper
to check that the disabled outputs mode are set to NULL, so add a
foreach output helper and change the tests to use that instead.

0aa7405a2a monitor-manager: Fall back to minimum screen size of 640 x 480
When headless, we don't have any logical monitors to derive a screen
size from, but we can't set it to empty as that will cause issues with
the clutter stage, UI widget layout and other things. To avoid such
issues, just fall back to a 640 x 480 screen size when headless.

8a32b42172 renderer/native: Round calculated framebuffer size before casting to int
Due to rounding issues, we can't assume a floating point calculation
will end up on an integer, even if we got the factor from the reverse
calculation. Thus, to avoid casting away values like N.999... to N,
when they should really be N+1, round the resulting floating point
calculation before casting it to int.

This fixes an issue where using the scale ~1.739 on a 1920x1080 mode
resulted in error when setting the mode, as the calculated size of the
framebuffer was only 1919x1080.

53175e8788 ScreenCast: Pass PipeWire stream node ID directly
As of commit 5f5ef3de2cdc816dab82cb7eb5d7171bee0ad2c5 in pipewire the
stream creator can find out the node ID of the stream it created.

So instead of using a special purpose entry to the info property box to
let the application discover stream by monitoring added nodes searching
for the given special purpose entry, just pass the node directly.

97f2c7c161 Add remote desktop and screen cast functionality
This commit adds basic screen casting and remote desktoping
functionalty. This works by exposing two D-Bus API services:
org.gnome.Mutter.ScreenCast and org.gnome.Mutter.RemoteDesktop.

The remote desktop API is used to create remote desktop sessions. For
each session, a D-Bus object is created, and an application can manage
the session by sending messages to the session object. A remote desktop
session the user to emit input events using the D-Bus methods on the
session object. To get framebuffer content, the application should
create an associated screen cast session.

The screen cast API is used to create screen cast sessions. One can so
far either create stand-alone screen cast sessions, or a screen cast
session associated with a remote desktop session. A remote desktop
associated screen cast session is managed by the remote desktop session.

So far only remote desktop managed screen cast sessions are implemented.

Each screen cast session may have one or more streams. A screen cast
stream is a stream of buffers of some part of the compositor content.
So far API exists for creating streams of monitors and windows, but
only monitor streams are implemented.

When a screen cast session is started, the one PipeWire stream is
created for each screen cast stream created for the session. When this
has happened, a PipeWireStreamAdded signal is emitted on the stream
object, passing a unique identifier. The application may use this
identifier to find the associated stream being advertised by the
PipeWire daemon.

The remote desktop and screen cast functionality must be explicitly be
enabled at ./configure time by passing --enable-remote-desktop to
./configure. Doing this will build both screen cast and remote desktop
support.

To actually enable the screen casting and remote desktop, the user must
enable the experimental feature. See
org.gnome.mutter.experimental-features.
