There seems to be a kernel race when one disconnects an external
monitor connected to a DisplayPort via a USB-C adapter. The race
results in a connector being reported as connected, but without any
modes supported.
This had the side effect that we tried to set a preferred mode to
the first listed mode, but as no modes were available, we instead tried
to dereference the first element of a NULL array, causing a
segmentation fault.
Mitigate this by skipping adding output if no supported modes are
advertised and the output doesn't support scaling, while moving the
fallback path for calculating a preferred output mode to after possibly
adding the common modes, to avoid the unvolentary NULL dereference.

Opening and closing the device may result into XI2 grabs being cut short,
resulting into pad buttons being rendered ineffective, and other possible
misbehaviors. This is an XInput flaw that fell in the gap between XI1 and
XI2, and has no easy fix. It pays us for mixing both versions, I guess...
Work this around by keeping the XI1 XDevice attached to the
ClutterInputDevice, this way it will live long enough that this is not
a concern.
Investigation of this bug was mostly carried by Peter Hutterer, I'm just
the executing hand.

When a window's workspace is not NULL, on_all_workspace should be FALSE.
Similarly, when on_all_workspace is TRUE, the window workspace should be
NULL.
This is an assumption in multiple places in the code, including when
setting the workspace state, the window is either added or removed from
all workspaces only if the window's workspace is NULL.
This rule is initially enforced at creation in _meta_window_shared_new()
when a initial workspace is set. However, when the initial workspace is
set from the session info, the initial workspace is not marked as “set”
which leads to an assertion failure when unmanaging windows, because the
window is not removed from all the workspaces.
When applying the session info to a window, mark the workspace as “set”.
https://gitlab.gnome.org/GNOME/mutter/issues/4Closes: #4
Having “on_all_workspaces_requested” FALSE on a window does not imply a
workspace is set.
If the X11 window is placed on a secondary monitor while workspaces
applies on primary monitor only (“workspaces-only-on-primary” set) then
“on_all_workspaces_requested” is FALSE while “on_all_workspaces“ is TRUE
and the associated workspace is NULL, leading to a crash when saving the
gnome-shell/mutter session.
So if no workspace is set, use the “initial_workspace” instead to avoid
a NULL pointer dereference.

Now that we have the list of supported modifiers from the monitor
manager (via the CRTCs to the primary planes), we can use this to inform
EGL it can use those modifiers to allocate the GBM surface with. Doing
so allows us to use tiling and compression for our scanout surfaces.
This requires the Mesa commit in:
Mesa 10.3 (08264e5dad4df448e7718e782ad9077902089a07) or
Mesa 10.2.7 (55d28925e6109a4afd61f109e845a8a51bd17652).
Otherwise Mesa closes the fd behind our back and re-importing will fail.

Using 800x600 as minimum logical size is very 4:3 thinking, while a lot of
modern devices are 16:9. The specific reason for this commit is to allow
1.5 scaling at mini-laptops (clamshell devices) with e.g. a 5.5"
1280x720 screen. Given that this device has a keyboard, one obviously
is not holding it very close to ones eyes and at 220 dpi that means the text
is too small at scale 1.0. For one real world example of such a device see:
https://en.wikipedia.org/wiki/GPD_Winhttps://bugzilla.gnome.org/show_bug.cgi?id=792765
Offer the text-input interface global, so it can be used by clients. The
MetaWaylandSeat will also let MetaWaylandTextInput intercept key events
before the keyboard interface handles those.
This is the implementation of the internal text-input protocol that will
be used to communicate IMs (to be implemented by gnome-shell) with clients.
The text_input protocol has its own focus expressed through enter/leave
events, that will typically follow the keyboard's.
The client will be able to communicate its current status (eg. focus state,
cursor rectangle in surface coordinates, text surrounding the cursor
position, ...) and will receive commands from the compositor (eg. preedit
text, committing a string, ...).
Whenever there is an active input method, the compositor will route key
events directly through it. The client will not receive wl_keyboard
events if the event is consumed by the IM.
Issuing a shortcut inhibit request for a surface without a window set
will lead to a crash when trying to show the shortcut inhibitor dialog.
In such a case, it's safer to deny the request.
https://bugzilla.gnome.org/show_bug.cgi?id=792599
The events might fall through if there's no corresponding active
pointer/keyboard/touch interface. Barring bugs this should be safe to do,
just a bit wasteful.
When maximizing a window, the previous location is saved so that
un-maximize would restore the same original window location.
However, if a Wayland client starts with a window maximized, the
previous location will be 0x0, so if we have to force placement in
xdg_toplevel_set_maximized(), we should update the location as well so
that the window is placed on the right monitor when un-maximizing.
For that purpose, add a new flag to force the update of the window
location, and use that flag from xdg_toplevel_set_maximized().
https://bugzilla.gnome.org/show_bug.cgi?id=783901
Wayland clients know their size better, so for Wayland we'd rather not
try to resize the client on un-maximize, but for this to work we need a
new MetaMoveResizeFlags.
https://bugzilla.gnome.org/show_bug.cgi?id=783901
When closing a window and showing a new one, the new one may not be
granted input focus until it gets a buffer on Wayland.
If another window is chosen to receive focus and raised on top of stack,
the newly mapped window is focused but placed underneath that other
window.
Meaning that for Wayland surfaces, we need to defer adding the window to
the stack until we actually get to show it, once we have a buffer
attached.
Rather that checking the windowing backend prior to decide if a window
is stackable or not, introduce a new vfunc is_stackable() which tells
if a window should be added to the stack regardless of the underlying
windowing system.
Also add meta_window_is_in_stack() API rather than checking the stack
position directly (replacing the define WINDOW_IN_STACK only available
in stack.c) and remove a window from the stack only if it is present
in the stack, so that the test in meta_stack_remote() becomes
irrelevant.

Wayland clients using the wl_shell interface were never receiving mouse
input. It meant they also couldn't be raised with a click.
This was because the call to meta_wayland_surface_set_window for wl_shell
surfaces did nothing while surface->window == window already. As such, it
never called clutter_actor_set_reactive() and the wl_shell window remained
a non-reactive actor.
Just make sure surface->window isn't already set before calling
meta_wayland_surface_set_window so it can actually do what it's meant to.

The device orientation coming out of iio-sensor-proxy defines upright/normal
as the direction in which the picture is displayed on the LCD panel without
any rotation. This is necessary for accelerometer rotation to work properly
in desktop environments which are not aware of panel-orientation issues.
This means that we need to correct the logical-monitor-config / user-visible
rotation for the panel-orientation when we get rotation info from
iio-sensor-proxy.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Just like we swap the x and y resolution of the monitor modes when
the panel-orientation requires 90 or 270 degree rotation to compensate,
we should do the same for the width and height in mm of the monitor.

If a monitor's max resolution is a portrait resolution, then assume it is

Even if the logical_monitor config does not have an active transform,
we might still be doing a transform under the hood to compensate for

If a LCD panel has a non normal orientation (mounted upside-down or 90
degrees rotated) then the kernel will report touchscreen coordinates with
the origin matching the native (e.g. upside down) coordinates of the panel.
Since we transparently rotate the image on the panel to correct for the
non normal panel-orientation, we must apply the same transform to input
coordinates to keep the aligned.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Some x86 clamshell design devices use portrait tablet LCD panels while
they should use a landscape panel, resoluting in a 90 degree rotated
picture.
Newer kernels detect this and rotate the fb console in software to
compensate. These kernels also export their knowledge of the LCD panel
orientation vs the casing in a "panel orientation" drm_connector property.
This commit adds support to mutter for reading the "panel orientation"
and transparently (from a mutter consumer's pov) fixing this by applying
a (hidden) rotation transform to compensate for the panel orientation.

If input happens to be grabbed somewhere along the shell, and ungrabbed
while a touch operation is ongoing, the wayland bits will happily start
sending wl_touch.update events from an undeterminate point, without

wl_touch.down wasn't received by the client, no other events will.

The reason why multiple keycodes could be mapped to a single keysym was
to support having both KEY_FAVORITES and KEY_BOOKMARK map to
XF86Favorites. However, iterating through all layout levels adding all
key codes has severe consequences on layouts with levels that map
things like numbers and arrow. The result is that keybindings that
should only have been added for keycodes from the first level, are
replaced by some unexpected keycode where the same keysym was found on
another level.
An example of this is the up-arrow key and l symbol. Normally you'd find
both the up-arrow symbol and the l symbol on the first level and be done
with it. However, on the German Neo-2 layout, layout level 4 maps the
KEY_E to the l symbol, while layout level 4 maps KEY_E to up-arrow.
Which ever gets to take priority is arbitrary, but for this particular
case KEY_E incorrectly mapped to up-arrow instead of the l symbol,
causing the keyboard shortcut Super+l, which would normally lock the
screen, to trigger the workspace-up (Super+up-arrow) key binding.

This protocol is limited to Xwayland only and is not visible/usable by
any other client.
Mutter uses the following mechanisms to determine if an X11 client
should be granted a grab:
- is "xwayland-allow-grabs" set?
- if set, is the client blacklisted?
- otherwise, has the client set the X11 window property
_XWAYLAND_MAY_GRAB_KEYBOARD on the window using a client message?
- if not, is it a client white-listed either via the default system
list or the settings "xwayland-grab-access-rules"?
https://bugzilla.gnome.org/show_bug.cgi?id=783342
Add a new client message "_XWAYLAND_MAY_GRAB_KEYBOARD" that X11 clients
can use to tell mutter this is a well behaving X11 client so it may
grant the keyboard grabs when requested.
An X11 client wishing to be granted Xwayland grabs by gnome-shell/mutter
must send a ClientMessage to the root window with:
- message_type set to "_XWAYLAND_MAY_GRAB_KEYBOARD"
- window set to the xid of the window on which the grab is to be issued
- data.l[0] to a non-zero value
Note: Sending this client message when running a plain native X11
environment would have no effect.

The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).
This was added in wayland-protocols 1.10.

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

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.

Bluetooth mouse usually goes in sleep state after a timeout, when that
happen the mouse is disconnected and on_device_removed function is

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

consequence that the cursor reappear. The id 0 is never given to devices

Under X11 we can only ever have the same scale configured on all

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.

First find the primary GPU and open it. Then go through all other

Get rid of some technical dept by removing the support in the native

The prefix, if any, of a variable name often contains information about

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

Move finding, opening and managment of the KMS file descriptor to

The monitor manager instance was created and setup in one step; at
construction. This is problematic if, in the future, the monitor manager

post init backend setup, "setup" the monitor manager state, i.e. read
the current state and setup the stage.

People that relied on xsetwacom to configure their tablets used to get
away with this by disabling the wacom g-s-d plugin prior to running
their scripts. This is not possible anymore with mutter managing device
configuration.
Given that X11 shall not go away soon and there's a core of stubbornly
accustomed users, provide a MUTTER_DISABLE_WACOM_CONFIGURATION envvar
to provide *some* way to do this.
To keep feature parity with the Wayland backend, and
to improve the overall tiling experience with GTK apps,
add the _GTK_EDGE_CONSTRAINTS X11 atom and update it
when necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=751857
Following up the previous patch, this patch makes the
Wayland backend send the edge constraints through a
custom protocol extension internal to GTK.
As it mature, we can think of upstreaming the protocol

https://bugzilla.gnome.org/show_bug.cgi?id=751857
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.
https://bugzilla.gnome.org/show_bug.cgi?id=751857
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
https://bugzilla.gnome.org/show_bug.cgi?id=645153
bar
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].
[1] https://wiki.gnome.org/GeorgesNeto/MinutesOfFeaneron/Tilinghttps://bugzilla.gnome.org/show_bug.cgi?id=645153
There is a variable in meta_window_edge_resistance_for_resize
that isn't really helpful: it just assumes TRUE, and is passed
to apply_edge_resistance_to_each_side.
This patch removes that useless variable and simply pass TRUE
instead.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
When windows are tiled, it improves the interaction with
them when they have a set of snapping edges relative to
the monitor. For example, when there's a document editor
and a PDF file opened, I might want to rescale the former
to 2/3 of the screen and the latter to 1/3.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
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.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
Now that tiled windows are resizable, the user may grow a tiled
windows until it covers the entire work area. As this makes the
window state mostly indistinguishable from maximization, avoid
subtle differences by properly maximizing the window in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
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.
Now that the preview tile mode has been split from the window's
tile_mode property, it is much more natural to pass the requested
tile_mode to the tile() function instead of setting it externally
and calling the function to apply the state.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
update_num_workspaces() is a no-op when the number of workspaces
did not actually change. That is fine, except that we still want

https://bugzilla.gnome.org/show_bug.cgi?id=760651
Automatic maximization is done when a window is almost the size of the
work area of a monitor. This makes no sense to try when there is no
monitor available, so skip trying to do this when headless.
https://bugzilla.gnome.org/show_bug.cgi?id=787637
When we are headless, treat this as if the window is always not monitor
sized. This might cause windows to temporarly become redirected while
being headless, but this is harmless as when a new monitor is
connected, we'll recalculate weather it should be redirected or not.

Check that configurations where monitors are disabled are properly
used. Also test that old configurations with explicitly disabled

https://bugzilla.gnome.org/show_bug.cgi?id=787629
When saving and restoring monitor configurations, we must take disabled
monitors into account, as otherwise one cannot store/restore a
configuration where one or more monitors are explicitly disabled. Make
this possible by adding a <disabled> element to the <configure> element
which lists the monitors that are explicitly disabled. These ones are
included when generating the configuration key, meaning they'll be
picked up correctly.

When dynamic workspaces are used, we pick up an existing NUMBER_OF_DESKTOP

We would free the shortcut inhibit data only when the client destroys

https://bugzilla.gnome.org/show_bug.cgi?id=787568
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.

Due to rounding issues, we can't assume a floating point calculation

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

When another D-Bus call that just tries to verify a configuration is
made, don't cancel any active monitor configuration dialog, as doing so
would effectively confirm queried configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=786023
When resolving what keycodes a key binding resolves to, only look up
key codes from the current layout group. Without this, unwanted
overlaps may occur. For example when a keymap has both a dvorak and a
qwerty layout on different layout groups, one keybinding may be bound
on multiple keys, arbitrarily "shadowing" another.
https://bugzilla.gnome.org/show_bug.cgi?id=786408
Add API to get the layout group (layout index) currently active. In the
native backend this is done by fetching the state directly from the
evdev backend; on X11 this works by listening for XkbStateNotify
events, caching the layout group value.
https://bugzilla.gnome.org/show_bug.cgi?id=786408
Don't wait for clutter to initialize for connecting to X11; do it when
constructing the backend instance. This way we can later depend on
having an X11 connection earlier during initialization.

When opening a laptop lid, one will likely want to restore the
configuration one had prior to closing it, so when ensuring monitor
configuration, first try to see if the previously set configuration is
both complete (all connected monitors are configured) and applicable
(it is a valid configuration) and only try to generate a new from
scratch if that failed.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
In order to go back in monitor configurations, save them to a history.
The history is implemented as a max 3 element long queue, where newly
set configurations are pushed to the head, and old are popped from the
tail.
The difference between using a single previous config reference and a
queue is that we can now remember the configuration used prior to a
D-Bus triggered configuration when the user discarded the configuration.
This will later be used to restore a previous configuration when a
laptop lid is opened.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
So far some basic testing, including:
* Test that the migrated configuration is applicable
* Test that a monitors.xml with multiple configurations are translated
* Test rotation
* Test tiled monitor discovery (well, test a made up tiled monitor
configuration since I don't have a real one)
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This commit changes the new configuration system to use monitors.xml
instead of monitors-experimental.xml. When starting up and the
monitors.xml file is loaded, if a legacy monitors.xml file is
discovered (it has the version number 1), an attempt is made to migrate
the stored configuration onto the new system.
This is done in two steps:
1) Parsing and translation of the old configuration. This works by
parsing file using the mostly the old parser, but then translating the
resulting configuration structs into the new configuration system. As
the legacy configuration system doesn't carry over some state (such as
tiling and scale used), some things are not available. For tiling, the
migration paths makes an attempt to discover tiled monitors by
comparing EDID data, and guessing what the main tile is. Determination
of the scale of a migrated configuration is postponed until the
configuration is actually applied. This works by flagging the
configuration as 'migrated'.
2) Finishing the migration when applying. When a configuration with the
'migrated' flag is retrieved from the configuration store, the final
step of the migration is taken place. This involves calculating the
preferred scale given the mode configured, while making sure this
doesn't result in any overlapping logical monitor regions etc.

The zero-initialized winsys id was incorrectly used as the key to find
the old output to base active/primary state from, which would never
succeed unless the winsys id happened to be 0. Fix this by using the
winsys id that will be used, i.e. the connector id.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The 'normal' transform has the value 0, so the g_warn_if_fail()
expression failed. Correct it so that it doesn't complain when no
transform is checked.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The problem is that libinput offers the possibility to not enabled
dragging when tap-to-click is enabled but mutter doesn't. For people who
have a sensitive touchpad and who like tap-to-click option, dragging is
launched even when you don't want it : for example, when you select a
folder, most of the time the folder is dragging whereas just selected or
when you want to select some lines of a text file, several lines are
moved as a cut-paste which is not expected and erase datas.
To fix it, you need to have the possibility to desactivate the drag
option when you use tap-to-click in mutter. Because it's already a
specification of libinput, it remains to add it to mutter.
Implementation with X11 is added too.
https://bugzilla.gnome.org/show_bug.cgi?id=775755
The meta_wayland_surface_hide_inhibit_shortcuts_dialog() function
disconnected the "destroy" handler, but we'd still be listening on
response events. Change this to just hide the dialog, leaving the data
intact with the proper life time signal in place.
https://bugzilla.gnome.org/show_bug.cgi?id=786385
The 'data' object is attached to the MetaWaylandSurface as a GObject
qdata. It is created once, and stays allocated until the surface is
destroyed. To make things clearer, connect to the "destroy" signal just
after creating, and from a on_surface_destroyed() callback call the
.._free() function.
https://bugzilla.gnome.org/show_bug.cgi?id=786385
When suspending (i.e. VT switching away, the GDM gnome-shell instance
gets hidden, or changing user), destroy the onscreen and offscreen
monitor framebuffers. When resuming, the stage views and framebuffers
will be recreated anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=786299
Plug the new MetaInhbitShortcutsDialog to the relevant Wayland protocol
implementation.
Also, remember the last user choice for a given surface to avoid asking
continuously the same question.
https://bugzilla.gnome.org/show_bug.cgi?id=783342
Add a mechanism to MetaWaylandSurface that inhibits compositor's own
shortcuts when the surface has input focus, so that clients can receive
all key events regardless of the compositor own shortcuts.
This will help with implementing "fake" active grabs in Wayland and
XWayland clients.
https://bugzilla.gnome.org/show_bug.cgi?id=783342
The cursor surface would be remembered until the next proximity in
event, causing flashing of the old cursor till the client underneath
the tablet tool sent the zwp_tablet_tool.set_cursor request.
Forgetting about the cursor surface on proximity out makes the cursor
invisible till the request is made.
More specifically, avoid crossing events, since clutter does not set
modifier/button state on those. Fixes implicit grabs being broken when
the pointer moves past the surface boundaries.

Since a wl_buffer is independent of the GL context in use (unlike, e.g.,
a GL renderbuffer), EGLImages with the EGL_WAYLAND_BUFFER_WL target must
pass EGL_NO_CONTEXT as the context. Quoting from the
EGL_WL_bind_wayland_display spec:
After querying the wl_buffer layout, create EGLImages for the
planes by calling eglCreateImageKHR with wl_buffer as
EGLClientBuffer, EGL_WAYLAND_BUFFER_WL as the target, NULL
context.
The check was already present inside _cogl_egl_create_image.

Moved from g-s-d's media keys plugin, where it was called "video-out",
since it requires changing the current monitor configuration and we
want to remove the old DBus API.
This implementation is intentionally simple and not really meant for
more than debugging and validating the various configurations. A
better user experience will be introduced in gnome-shell with a custom
keybinding handler.
The default value includes <Super>P in addition to the standard keysym
for historical reasons.
https://bugzilla.gnome.org/show_bug.cgi?id=781906
This will allows us to support the XF86Display key present on some
laptops, directly in mutter. This is also known, in evdev, as
KEY_SWITCHVIDEOMODE.
The common usage for this key is to alternate between a few well known
multi-monitor configurations though these aren't officially
standardized. As an example, Lenovo documents it as:
"Switches the display output location between the computer display
and an external monitor."
On this patch, we're just introducing the configurations that have been
implemented in g-s-d until now, which go a bit beyond the above
description.
https://bugzilla.gnome.org/show_bug.cgi?id=781906
Test that a tiled monitor with tile (0, 0) as the non-main output,
where main output is defined as the output that is active as long as
the monitor is active.
https://bugzilla.gnome.org/show_bug.cgi?id=781723
Instead of letting MetaMonitor derive the logical monitor size, then
using the main monitor for the position, just let MetaMonitor derive
the whole layout including the position. This means it can deal with
tiled monitors better, for example when the main output (the output
always active when the monitor is active) is not the origin output (the
output with tile position (0, 0)).
https://bugzilla.gnome.org/show_bug.cgi?id=781723
Adds basic support for the "wheel" event from the Wayland tablet protocol.
Ideally we would accumulate the angle and report a wheel event with an
appropriate value for "clicks". We can get away with a much cruder method
for the time being, however, since no Wacom tablet puck actually provides
a smooth scrollwheel. Checking whether the angle in CLUTTER_INPUT_AXIS_WHEEL
exceeds a nominally-small threshold is sufficient to determine that the
wheel has advanced by at least one physical click.
https://bugzilla.gnome.org/show_bug.cgi?id=783716
When updating the main monitor, make sure to update the toplevel main
monitor before trying to use that as the main monitor for non-toplevel
windows (such as popups). Without this, when the main monitor is
updated as a side effect to monitors being changed (for example due to
a hot plug event, or coming back from being suspended) the
main monitor pointer may, after 'monitors-changed' has completed, point to
freed memory resulting in undefined behaviour.
https://bugzilla.gnome.org/show_bug.cgi?id=784867
This is used to request key focus on the close dialog whenever
a window that is frozen would receive key focus. Also, ensure
that the dialog gets focus when first shown if the window was
meant to receive input.
https://bugzilla.gnome.org/show_bug.cgi?id=762083
Otherwise the ClutterEventFilter will consider these handled, and not
forward these to Clutter. This gets necessary for key handling if we
mean to implement the close dialog with Clutter UI.
https://bugzilla.gnome.org/show_bug.cgi?id=762083
The list of files being parsed for enumerations include the header file
we are building with the enumeration types.
Additionally, we are concatenating multiple runs in the same temporary
files; on failure, the temporary files are left around, which means we
end up with broken headers and sources.
Just like we do for buttons, with a few twists. These have 2 directions
mappable to different keycombos, and are affected by the current mode
in their group.
https://bugzilla.gnome.org/show_bug.cgi?id=782033
Moved from g-s-d's media keys plugin, where it was called
"video-rotate", since it requires changing the current monitor
configuration and we want to remove the old DBus API.
https://bugzilla.gnome.org/show_bug.cgi?id=781906
This basically moves g-s-d's orientation plugin into mutter so that
eventually g-s-d doesn't need to build monitor configurations by
itself anymore.

Since commit 6b5cf2e, we keep override redirect windows on a layer
above regular windows in the clutter actor scene graph. In the X
server, and thus for input purposes, these windows might end up being
stacked below regular windows though, e.g. because a new regular
window is mapped after an OR window.
Fix this disconnect by re-stacking OR windows on top when syncing the
window stack with the compositor.
https://bugzilla.gnome.org/show_bug.cgi?id=780485
When verifying if a configuration is applicable, don't set it as
current when applying succeeded, or else reverting to a previous
configuration doesn't work after having verified.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
Differentiate between non-interlaced and interlaced modes. This is done
by appending an "i" after the resolution part of the mode ID, and
adding a 'is-interlaced' (b) property to the mode properties.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
To be more flexible without having to change any D-Bus type signatures
in the future, replace the 'uint' flags value (currently determining
whether a mode is current and/or preferred) with a variant lookup table.
The keys 'is-current' (b) and 'is-preferred' (b) replace the existing
flags.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
To be able to add more modes types that happen to have the same
resolution and refresh rate, change the API to specify modes using an
ID string. The ID string is temporary, and only works for associating a
mode for the monitor instance that it was part of.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When calculating sizes given some size and a fractional logical monitor
scale with precision loss, round the result of the floating point
calculation to the closest integer, as otherwise we might end up with
result smaller by 1 if there was a loss of precision when calculating
the scale.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
To be able to render the pointer cursor sprite at sub-(logical)-pixel
positions, track the pointer position using floats instead of ints.
This also requires users of the cursor sprite rect to deal with
floating points, when e.g. finding the logical monitor etc.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When passing scales over D-Bus, we'll loose some precision. To set the
correct scale, use the configured scale and look up the one actually
supported by the monitor mode, and use that. To match the supported one
with the configured one, the difference must be within rounding error
range.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
We manually scaled pointer motions when they travel over a scaled
monitor. When a stage view of a monitor is also scaled, in practice this
meant we scaled twice. Avoid this by only manually scaling the pointer
motion when stage views are not scaled.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When using logical sized monitors we are allowed to use fractional scaling
but only if the resulting scaled logical monitor size is in integer form.
So, in order to get this, we allow to scale the monitor to up to
8 fractional values per integer, doing some computation in order to
fetch the nearest values which are closer to the scaling factors we can
permit.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
This changes the API to pass supported scales per mode instead of
providing a global list. This allows for more flexible scaling
scenarious, where a scale compatible with one mode can still be made
available even though another mode is incompatible.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When the logical layout mode is used, allow configuring the scaling to
be non-integer. Supported scales are so far hard coded to include at
most 1, 1.5 and 2, and scales that doesn't result in non-fractional
logical monitor sizes are discarded.
Wayland outputs are set to have scale ceil(actual_scale) meaning well
behaving Wayland clients will provide buffers with buffer scale 2, thus
being scaled down to the fractional scale.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
To support fractional scaling, change the stage view scale to be a
float instead of an int. Also change the places where it is retrieved
and used when scaling things.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
Previously gnome-shell listened on the Xft Xsettings via GTK+s
GtkSettings to get the font DPI setting. The Xsetting might not
be what we want, and we should not rely on Xsettings when we don't need

The caller in clutter really expects an error if fd==-1, so make

Window moving and resizing depends on the `meta_wayland_seat_get_grab_info`
