When mutter is paused (i.e. not the DRM master), stop listening on
hotplug events. Instead read the current state and set modes when
resumed.
This avoids a race condition in the drm API which currently only
manages to properly deal with one application querying the EDID state
at the same time when there are multiple mutter instances running at
the same time (e.g. gnome-shell driving gdm at the same time as
gnome-shell as the session instance).

If the dnd window ends up lower in the overall stack than the window
it's supposed to fence, the drop might end up in some other window

Maps and raises the dnd window each time it's shown so that it's always

A MetaOutput is a connector, not exactly a monitor or a region on the
stage; for example tiled monitors are split up into multiple outputs,
and for what is used in input settings, that makes no sense. Change
this to use logical monitors instead of outputs.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
When no output was specified, the screen limit was used to calculate the
aspect ratio. The screen limit, however, is either just an arbitrary
number if no screen limit is applicable, or a hardware graphics buffer
limit, which has nothing to do with anything actually displayed. Change
it to use the screen size instead, to get something that makes more
sense when no output is found.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Expose via a new API whether the transform on a logical monitor is
handled by the backend. This was previously only exposed only in the
native backend. This will be used to emulate not supporting transforms
in the backend in the nested backend.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Previously, the size of the logical monitor was derived directly from
the tiling information. This works fine until we add transformations,
or set modes with a dimension different from the resulting resolution
when tiled. Fix this by traversing the assigned CRTC rects, as these
are already transformed by the configuration system.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
By setting the environment variable MUTTER_DEBUG_TILED_DUMMY_MONITORS
to "1", the dummy MetaMonitorManager backend used when running mutter
nested will create tiled monitors instead of single-output/CRTC
monitors. This makes it possible to test tiled monitor configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Refactor monitor generation by splitting the generation of modes, CRTCs
and outputs into a separate function. A side effect is that each output
will have its own set of possible modes.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Split up logical monitor cration into derived (when derived from
current underlying configuration) and non-derived (when creating from a
logical monitor configuration). This avoids that type of logic in the
logical monitor creation function.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Add support for non-tiled monitor modes on tiled monitors. This is done
by adding all the other supported modes, except the modes with the

When adding a monitor and all its outputs, don't try to set the logical
monitor of the outputs CRTC if none was assigned. This might happen if
a tiled monitor only uses a subset of the connectors it are connected
via.

Don't set the CRTC rect and screen size at in read_current(), as those

QT apps reject DnD if the timestamp received in the SelectionRequest

Bookkeeping and using it in XConvertSelection makes it happy again.
https://bugzilla.gnome.org/show_bug.cgi?id=779757
We are keeping accounting of the focus window as seen by the DnD bridge
right here, so use it instead of the MetaWaylandDragGrab focus as it may
lag behind the real focus (i.e. till the drag source notices the window
and sends XdndEnter to it).
This leads to the window trying to be repositioned more often than
necessary when the drag source takes long to send the XdndEnter client
message, and maybe not repositioned at all if the pointer leaves the
surface while no XdndEnter message was received.
https://bugzilla.gnome.org/show_bug.cgi?id=763246
We currently wait for the selection being cleared by the drag source,
which might not happen on not quite educated clients. This may leave
a stuck XDND grab in the compositor side.
We can actually do a bit better, and clear the grab if:
1) The drag source sent XdndDrop to the wayland drag destination.
2) There's no accepting drag destination and all pointer buttons are
released.
3) As usual, whenever the drag source clears the selection data
https://bugzilla.gnome.org/show_bug.cgi?id=763246
No XDnD events which notify DnD status change comes in Wayland. To emulate XDnD
behavior, MetaDnd checks whether there is a grab or not when the modal window
starts showing. When there is a grab, it processes the raw events from
compositor, and emits DnD signals for plugin.
https://bugzilla.gnome.org/show_bug.cgi?id=765003
Implement MetaDnd for emitting DnD signals to plugins such as gnome-shell. The
xdnd handling code comes from gnome-shell, and it is hidden behind MetaDnd now.

When running nested, the pointer can be outside of the stage, meaning

Whenever an EGLOutput consumer is temporary unable to handle

Ungrabbed pointer motion events over a client window area don't even
reach mutter in X compositor mode, but as a wayland compositor we
process those events which ends up in a call stack like:
- meta_window_handle_ungrabbed_event
- meta_ui_frame_handle_event
- handle_motion_notify_event
- get_control
- meta_ui_frame_calc_geometry
Computing frame geometry is a relatively CPU expensive operation and
doing it on every motion event over a client window is pointless work
since we aren't going to change the cursor or prelight any frame
widget.
This commit special cases the determination of
META_FRAME_CONTROL_CLIENT_AREA using a much faster method. When
continuously moving the pointer over an X (client) window, it results
in a ~40% decrease in mutter cpu usage.
https://bugzilla.gnome.org/show_bug.cgi?id=779436
Set up things so that if the INTEL_swap_event extension is not present,
but the driver is known to have good thread support, we use an extra
thread and call glXWaitVideoSync() in the thread. This allows idles

otherwise, without INTEL_swap_event, we'll just block in glXSwapBuffers().

Commits 6dbec6f8, 734402e1 and f041b35b introduced memory leaks by
switching to returning copies instead of the original buffers but
forgetting to free those original buffers.
Some error cases were also not freeing the ->prop buffer as they
should.
https://bugzilla.gnome.org/show_bug.cgi?id=642652
Wayland windows can be zero sized until clients attach a buffer, but
our rectangle code doesn't deal with this case well, in particular,
meta_screen_get_monitor_for_rect() might end up choosing the wrong
monitor for a zero sized rectangle since
meta_rectangle_contains_rect() considers a zero sized rectangle at the
right or bottom edges of another rectangle (the monitor's) to be
contained there.
Since out size limits constraint will enforce a minimum size of 1x1,
we might as well enforce that when setting up the constraint info so
that the correct monitor gets chosen and the single monitor constraint
doesn't move these windows to the wrong one.
https://bugzilla.gnome.org/show_bug.cgi?id=772525
Wayland windows are initially zero sized until clients commit the
first buffer. Despite being invisible, clients are allowed to request
such windows to be fullscreened on a specific output before they
attach the first buffer which means we need to be able to move them.
meta_window_move_to_monitor() doesn't handle this case because these
windows' initial monitor is a placeholder since their initial
coordinates are 0,0+0+0, which results in us using a rectangle as
old_area for meta_window_move_between_rects() that might be to the "right"
of the window causing the move to go further out of the visible
screen's coordinates. This is later "corrected" by the constraints
system but the window might end up in the wrong monitor.
To fix this, we can make meta_window_move_between_rects() accept a
NULL old_area, meaning that we move the window to the new_area without
trying to keep a relative position.
https://bugzilla.gnome.org/show_bug.cgi?id=772525
The reason for the display to be closed may be meta_screen_new()

We currently don't have any shadow class for combo box popups,
which means the default shadow of normal windows is used. That's
clearly odd given that the two are very different, and isn't

we could add a dedicated shadow class, the designers are fine
with reusing the existing shadow for dropdown-menus, so let's
do that.

Split up the X11 backend into two parts, one for running as a

In order to minimize the amount of breakage, while at the same time
making it easier to make backward incompatible changes needed to
continue turning libmutter into a capable Wayland compositor, make the
libmutter and friends (libmutter-clutter, libmutter-cogl*) parallel
installable by adding a version number to the name. This changes
various filenames, for example what previously was libmutter.so is now
libmutter-0.so (assuming the version for now is 0), and
libmutter-clutter-1.0.so is now libmutter-clutter-0.so. The pkg-config
filenames and GObject introspection has been renamed to reflect this as
well.
This enables a downstream compositor rely on a specific version of the
libmutter API, while gracefully handling API/ABI changes by having to
update to the new version at their own pace.

Make sure that each logical monitor owns the expected actual monitors.
This currently needs special care when dealing with laptop lid the

This is partly redundant given that the current monitor mode is checked

The main output of the main (first) monitor of a primary logical

The new monitor configuration system (MetaMonitorConfigManager) aims to
replace the current MetaMonitorConfig. The main difference between the
two is that MetaMonitorConfigManager works with higher level input
(MetaMonitor, MetaMonitorMode) instead of directly looking at the CRTC
and connector state. It still produces CRTC and connector configuration
later applied by the respective backends.
Other difference the new system aims to introduce is that the
configuration system doesn't manipulate the monitor manager state; that
responsibility is left for the monitor manager to handle (it only
manages configuration and creates CRTC/connector assignments, it
doesn't apply anything).
The new configuration system allows backends to not rely on deriving the
current configuration from the CRTC/connector state, as this may no longer be
possible (i.e. when using KMS and multiple framebuffers).
The MetaMonitorConfigManager system is so far disabled by default, as
it does not yet have all the features of the old system, but eventually
it will replace MetaMonitorConfig which will at that point be removed.
This will make it possible to remove old hacks introduced due to
limitations in the old system.

Sometimes we hit a race on hot-plug where we try to read the KMS

A monitor spec object is meant to be used to identify a certain monitor
on a certain output. The spec is unique per actual monitor and connector,
meaning that a monitor that changes from one connector from another

to associate for example a configuration entry with an actual monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a "mode spec" concept, meaning to be used as a identifier for an
actual monitor mode. It consists of details making a mode unique, i.e.
the total resolution and refresh rate. This will later be used to get
the actual monitor mode (set of one or more CRTC modes).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add "monitor modes" abstracting the modes set on a monitor. On normal

Don't store logical monitor specific state in an array where the index

Instead of storing the logical monitors in an array and having users

Use the proposed EGL_WL_wayland_eglstream EGL extension instead of the
file descriptor hack that was used as a temporary solution.
Note that this results in EGL clients will no longer work if they are
running on a Nvidia driver with a version older than 370.

Instead of having a way to determine the type of a buffer, add a
realization step that implicitly detects the buffer type. This makes it
possible to both realize (i.e. creating needed objects from the buffer)
and determine the type at the same time, which may be the only possible
way (for example, the only way to know whether a buffer is a EGLStream
is to create the EGLStream from it).

When the monitor the surface is on has a scale other than 1, the
coordinate of the window menu popup position needs to be scaled, as it
is reported in logical pixels, while the stage is still in physical
pixels.

A window manager must select the SubstructureRedirect mask on the root
window to receive the MapRequest from the X11 clients and manage the
windows. Without this event mask set, a window manager won't be able to
map any new window.
The Wayland selection code in mutter can change/clear the event mask on
the requestor window from a XSelectionRequest event when the window is
not managed by mutter/gnome-shell.
A rogue or simply buggy X11 client may send a XConvertSelection() on the
root window and mutter will happily change/clear its own event mask on
the root window, effectively turning itself into a regular X11 client
unable to map any new X11 window from the other X11 clients.
To avoid this, simply check that the requestor window is not the root
window prior to change/clear the event mask on that window.

Commit 5eb5f72 - wayland: Check surface outputs after mapped state
changes connected the ::mapped signal handler, we need to disconnect it
on destroy to avoid a possible assertion failure in
update_surface_output_state()
