When the top window actor is destroyed, we need to make sure that
all its references are removed or it could be picked again in next
windows sync, causing crashes.
Since the window might or might not be destroyed when removed (depending
weather animations are in progress over it or not), it's just safer
to wait it to be destroyed before cleaning up any of its reference.

Changing the test monitor managers ability to rotate CRTCs in one test

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.
https://bugzilla.gnome.org/show_bug.cgi?id=788915
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.
https://bugzilla.gnome.org/show_bug.cgi?id=788915
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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=790358
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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
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.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
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.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
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.

We must emit ::dnd-leave to pair the ::dnd-enter that shall be

We tried to get the geometry scale, which may depend on the main

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.

The DRM properties container must be destroyed with
drmModeFreeObjectProperties, and the connectors must be freed on every

This is not a leak per se, but it seems too easy to make valgrind

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.

The handlers depend on a role being assigned. Destroying the window
causes it to become unmapped, which would sometimes trigger one of the
handlers, resulting in an is-assigned assert hitting in one of the
handlers. Avoid this by disconnecting the handlers earlier, so that
there is no risk that any them being triggered before the role is
assigned.

In the unlikely case that a surface is moved by the compositor while
holding a pointer confinement, we also need to update the pointer
position when the surface actor gets moved.
https://bugzilla.gnome.org/show_bug.cgi?id=782344
Both notify::position on the surface actor and position-changed on
MetaWindow are listened to, in order to trigger wl_output updates for
wl_surfaces whenever the surfaces move across them.
Both signals are necessary in order to cater for toplevel and subsurface
relocations (Because it's the parent window actor what changes position
in this last case).
Also, shuffle signal disconnection, so each signal goes away with
the object reference held by MetaWaylandSurface.

It looks that there are some extensions that run a Mainloop on startup,
causing to dispatch a clutter paint before the compositor is even available.
In such scenario a MetaWindow could try to start a simple effect
using a compositor plugin which is not there yet.
Then in order to catch these bugs we can now assert that the expected
conditions are valid, so that gnome-shell will provide a dumpstack to
debug the real offending JS code.
https://bugzilla.gnome.org/show_bug.cgi?id=789223
There are cases when no compositor is available (yet) but a MetaWindow tries
to start a simple effect using a compositor plugin which is not available.
In that case we should just ignore any request and protect ourselves from
crashes.
https://bugzilla.gnome.org/show_bug.cgi?id=789223
This function might be called by components with invalid plugin manager
(as it might happen to MetaWindow when the compositor isn't initialized
properly), so we need to protect ourselves from crashes.

Check that if there are multiple modes with the same ID (resolution,
refresh rate and handled flags) we correctly add the preferred mode to
the list of monitor modes.
https://bugzilla.gnome.org/show_bug.cgi?id=789153
When generating MetaMonitorMode's, prefer CRTC modes that has the same
set of flags as the preferred mode. This not only is probably a better
set of configurable modes, but it'll guarantee that the preferred mode
is added.
This fixes a crash when the preferred mode was not the first mode with
the same resolution, refresh rate and set of handled modes.
https://bugzilla.gnome.org/show_bug.cgi?id=789153
Under X11 we can only ever have the same scale configured on all
monitors. In order to use e.g. scale 2 when there is a HiDPI monitor
connected, we must not disallow it because there is a monitor that does
not support scale 2. Thus we must show the same scale for every monitor
and monitor mode, even though it might result in a bad experience.
Do this by iterating through all the monitors adding all supported
scales by the preferred mode, combining all the supported scales. This
supported scales list is then used for all monitor and modes no matter
what.

When determining whether we should unredirect a window or not, ignore
offscreen windows, and just check the top most visible window.
Previously this was not an issue, but since 'stack-tracker: Keep
override redirect windows on top' we started sorting the UI frames
window, which is an offscreen override redirect window, on top, causing
the unredirect checking code to always check whether to unredirect the
UI frames window. This effectively disabled the compositor bypass
functionality.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
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.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Add helper functions and macros for managing and drawing OpenGL ES 3.
It will be used for blitting framebuffers between multiple GPUs in
hybrid GPU systems.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Eventually, we'll render buffers without using Cogl, and for this we
need to be able to do things like creating, destroying and changing the
context, as well as swapping buffers.

First find the primary GPU and open it. Then go through all other
discovered GPUs with connectors and add those too. MetaRendererNative

MetaCursorRendererNative still always falls back on OpenGL based cursor
rendering when there are multiple GPUs.

Make dumb buffer creation/destruction reusable by introducing a

Get rid of some technical dept by removing the support in the native
backend for drawing the the whole stage to one large framebuffer.
Previously the only way to disable stage views was to set the

The prefix, if any, of a variable name often contains information about
the namespace (such as clutter_backend is the ClutterBackend, while
backend is a MetaBackend). Clean up some more inconsistencies in

but in fact was Cogl types.

In order to eventually support multilpe GPUs with their own connectors,
split out related meta data management (i.e. outputs, CRTCs and CRTC
modes) into a new MetaGpu GObject.
The Xrandr backend always assumes there is always only a single "GPU" as
the GPU is abstracted by the X server; only the native backend (aside
from the test backend) will eventually see more than one GPU.
The Xrandr backend still moves some management to MetaGpuXrandr, in
order to behave more similarly to the KMS counterparts.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Pass the backend to a new factory function, and keep a pointer to the
monitor manager, which is accessed elsewhere in the same file instead of
fetching the singleton. The HW cursor initialization part is also made
more obvious, without depending on seemingly irrelevant clutter
features.

Move finding, opening and managment of the KMS file descriptor to
MetaMonitorManagerKms. This means that the monitor manager creation can
now fail, both if more than one GPU with connectors is discovered, or
if finding or opening the primary GPU fails.

The monitor manager instance was created and setup in one step; at
construction. This is problematic if, in the future, the monitor manager
creation can fail, as the monitor manager is created quite late.
To make it possible to in the future fail creating a monitor manager,
create the instance very early when initiating the backend, then on
post init backend setup, "setup" the monitor manager state, i.e. read
the current state and setup the stage.
