We currently only save synchronously when running the test suite, but
should still not leak the generated config buffer. We also created the
cancellable but never used it if we saved synchronously, so lets stop
doing that too.

The cancellable should only be cleared if we weren't cancelled, as if
we were cancelled, the path cancelling have already cleared the

We cleaned up an unused monitor config list, but what we should do is
clear up the logical monitor config list. This commit does that, as

We would free the shortcut inhibit data only when the client destroys
its request, which is not the case when the clients itself is
destroyed, leading to a leak of the shortcut inhibit data.
Free the data on resource destruction instead, and simply destroy the
resource on destroy request.
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.

Give clients (such as Xwayland) a chance to bind the wl_output global

This avoids updating state (such as position, size etc) when going

In order to give the clients the best chance to bind the wl_output

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

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.

When headless, we don't have any logical monitors to derive a screen

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.

As of commit 5f5ef3de2cdc816dab82cb7eb5d7171bee0ad2c5 in pipewire the

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.

When monitors changed, previous monitor instances are defunct, and any
reference holder should drop its reference. Sometimes they will want to
continue having a reference to the same monitor, so add this function

The HW cursor plane can't do any transformations, and as we still don't
pre-transform any buffer before uploading to the cursor plane, we must
disable the HW cursor when a logical monitor is transformed.
This worked previously because the transform of a MetaCrtc did not
correspond to the transform of a CRTC, but the transform of the logical
monitor the CRTC was assigned to.

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

Don't wait for clutter to initialize for connecting to X11; do it when

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.

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 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.

The meta_wayland_surface_hide_inhibit_shortcuts_dialog() function

Since a wl_buffer is independent of the GL context in use (unlike, e.g.,

After querying the wl_buffer layout, create EGLImages for the

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

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.

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)).

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.

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.

The list of files being parsed for enumerations include the header file

Additionally, we are concatenating multiple runs in the same temporary

Differentiate between non-interlaced and interlaced modes. This is done

When calculating sizes given some size and a fractional logical monitor

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

with the configured one, the difference must be within rounding error
range.

We manually scaled pointer motions when they travel over a 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.

When the number of (static) workspaces decreases, we relocate windows
from extra workspaces before removing them. As removing a non-empty

However that assert is

the workspace is empty
- wrong, because even empty workspaces contain windows that are set

It is possible to interpret the ammount of padding provided to the
*_set_tablet_area functions in two different and incompatible ways. The X11
backend effectively treats them as being input-centric (i.e., the padding
defines the size of the "dead zone" on the tablet) while the native backend
has an output-centric viewpoint (i.e., the padding defines the size of the
"dead zone" on the display) viewpoint. This difference in opinion causes the
cursor offset to change when switching between Xorg and a Wayland sessions.
The calibration utility within g-c-c does its calculations with an input-
centric viewpoint, so this patch modifies the native backend to work
correctly with these values. To change viewpoints, we can simply invert
the scale and negate the offset. It should be noted that this function
also forgot to apply scaling to the offsets (as required by the matrix
transform done by libinput) which would have further compounded the
cursor offset issue under Wayland.

It would only allow to alternate between the logical monitors, we actually
want to return NULL here so it can cycle to the whole span of monitors.

Instead of checking all MetaMonitors in the monitor manager, we want to
look (as the function name says) in the MetaMonitors contained in the
given logical monitor.
Otherwise, it will return TRUE for every logical monitor, given we are
querying for an existing EDID.

Due to the pen/eraser device separation in X11, CLUTTER_TABLET_DEVICE does

For devices connected via HDMI (supposedly TVs) we want have a
scale factor of 1 if we are *below* the smallest 4k resolution

ported from gnome-settings-daemon.

Previously, the function only returned `TRUE` if the given surface was
equal to the given pointer's focused surface. This changes the behaviour
to also return `TRUE` if any of the given surface's subsurfaces are

For size change animations, plugins rely on the size change effect being
followed by size changed signal (or effects being kill altogether).
However unless the move_resize operation included the STATE_CHANGED flag,
the size changed event emitted when the compositor syncs the window
geometry only happens when the operation resulted in an actual change.
To avoid animations getting stuck in that case, make sure to include the
flag when tiling a window.

Use the "destroy" MetaWaylandSurface signal instead of the wl_resource
destroy signal for tracking the lifetime of the surface with pointer
focus.
As unsetting the focus may have side effects due to handlers of the
"focus-surface-changed" signal, connect the signal after the default
handler to make sure other clean up facilities have the chance deal with
the surface destruction before we try to unset the focus.

A single keysym can resolve to multiple keycodes. Instead of only using
the first one and ignoring the others, we store all codes in
MetaResolvedKeyCombo and then handle all of them in keybinding
resolution. If we already have bound a keycode for a keybinding with a
specific keysym then this can get overwritten by a new keybinding with a
different keysym that resolves to the same keycode. Now that we resolve
and bind all keycodes for a keysym this might happen more often; in that
case warn but still overwrite, but only for the first keycode for each
keysym. If a secondary (i.e. all non-first keycodes) is already indexed
we just ignore that; this should resemble the old behavior where we
only took the first keycode for any keysym as close as possible.

We will both create and destroy monitors during initialization (when
using the X11 backend), so don't try to access the monitor manager from
the backend, but store a pointer to it instead.
It's stored in MetaMonitor even though only MetaMonitorTiled uses it,
mostly because it makes more sense to store such a pointer there.

In some circumstances, the origin tile (0, 0) is not the one that
should be used to drive the monitor when using a non-tiled mode. Update
MetaMonitorTiled to support this case. It also seems to be so that the
preferred mode might be some low resolution or bogus mode on these
monitors, so also adapt MetaMonitorTiled to manage to ignore the
preferred mode of a tiled monitor if the preferred mode doesn't use
both tiles.
https://bugzilla.gnome.org/show_bug.cgi?id=781723
Only support suggested monitor positioning if the monitor is non-tiled.
Normally this functionality is used by virtual machines to provide a

This commit makes it possible to configure logical monitor scale also
when running on top of an X11 server using Xrandr. An extra property
'requires-globla-scale' is added to the D-Bus API is added to instruct
a configuration application to only allow setting a global logical
monitor scale.
This is needed to let gsd-xsettings use the configured state to set a
XSettings state that respects the explicit monitor configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The scale calculation doesn't really have anything to do with KMS, and
eventually we'll want to have mutter calculate the monitor scale for

hotplug_mode_update is used (mostly by VMs nowadays, and
VMware has implemented it) to inform that modes list (including

However, when using MetaMonitorConfigManager we should

Disable-while-typing disables the touchpad while the user is typing.
This patch introduces the necessary backend code to implement the
org.gnome.desktop.peripherals.touchpad.disable-while-typing setting of
gsettings-desktop-schemas which was implemented in commit
4c5b1c1df399d6afaaccb237e299ccd1d5d29ddd and released as part of 3.24.
This is known as dwt in libinput.
This patch has been tested on X11 and Wayland.

Relayouts in clutter may trigger synthesized crossing events if the

When terminating mutter running as a display server, don't try to resize
maximized windows when unmanaging, as at this point, they will have no
MetaWaylandSurface. Originally this was done instead of setting the
net_wm_state to not mess with future window managers, but when we're a
Wayland compositor, this does not matter.
https://bugzilla.gnome.org/show_bug.cgi?id=782156
If a client changes the state of a surface to issue a set_maximize, this
causes apply_pending_state() to be called before mutter has placed the
window.
If the monitor on which the window is to be shown initially is different
from the one where the pointer is placed, this causes the effect to be
played at the wrong location before the window eventually reaches its
location on another monitor.
Force the window to be placed prior to change its state to maximized in
xdg-shell so that mutter won't relocate the window afterwards.
This also avoids sending an xdg_toplevel.configure with a size of 0x0
which would cause the client to initially draw its surface with some
arbitrary size.

If we translate between text/plain;charset-utf-8 from the wayland side to

Previously we would bail out early in xdg_toplevel_role_commit() if no
geometry change was set, ignoring the possible min/max size hints
changes.
But setting a min/max size hint without changing the geometry is
perfectly valid, so we ought to apply the min/max changes regardless of
a geometry change.
https://bugzilla.gnome.org/show_bug.cgi?id=782213
If the client doesn't set a geometry using xdg_shell, we'll compute its
geometry based on its surface and subsurfaces.
Yet, we translate that as a window (re)size only when there is a pending
geometry, that we don't have when we computed the geometry by ourself.
Make sure we set the pending new geometry flag when computing the
geometry when it actually changed.
https://bugzilla.gnome.org/show_bug.cgi?id=782213
A client can still commit state to a destroyed subsurface. It wont
update anything on the screen, since the subsurface will not be

g_hash_table_insert() doesn't replace the key. This was a problem
because the key was owned by the value inserted into the hash table, so
when a value was removed, the key was freed, meaning that the key in
the hash table was no pointing to freed memory. Fix this by using
g_hash_table_replace() instead, which work the same except that it
replaces the key with the one passed. This means that the key of a
value in the hash table is always the key owned by the value.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The guard for handling size differences between keys were broken, it

An inactive monitor will not be assigned to a logical monitor, so don't
try to match against those. This avoids a dereferencing a NULL when the

Instead of looking at the GTK+ settings, check the logical monitor
state and determine the UI scaling factor given the maximum logical
monitor scale. This is only enabled when the monitor config manager
feature is enabled, as only then can a scale be explicitly configured.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This adds a function to be used by gnome-shell to get the logical
monitor given a connector name. For now, use the same index integer
method to reference a logical monitor, but this should be revisited by
providing a better API later.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The connector returned is the one of the main output. In other words,
for tiled monitors, it is the connector of the (0, 0) tile, and for
non-tiled, it is simply the connector of the output.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The UI scaling depends on whether the framebuffers are scaled. Enable
the caller to determine the what scale its UI should be drawn in, in
relation to the stage coordinate space by calling this function. A new

Window scaling is a clutter feature used to enable automatic scaling of
stage windows when running under as an application in windowing system.
Clutter in mutter does not support running as a stand-alone application

When told to, MetaMonitorConfigStore will save the current
configuration state by replacing the monitors-experimental.xml file
(while backing a backup).
https://bugzilla.gnome.org/show_bug.cgi?id=777732

In order to test deriving the logical state from the underlying

Derive the logical monitor position not by looking at the main output
(the (0, 0) tile), but the one that is placed on the top-left corner.
This might be the non-main output on certain transformations.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Only the first output of the first monitor of the primary logical
monitor should be made primary. This fixes an issue where the wrong
logical monitor ended up as primary when the logical state was derived.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Make the nested backend emulate how the real backends actually draw,
i.e. by drawing each CRTC separately. This makes it possible to test
different configuration paths that can take place on different
hardware, without having said hardware.
For example, by setting MUTTER_DEBUG_TILED_DUMMY_MONITORS and
MUTTER_DEBUG_NESTED_OFFSCREEN_TRANSFORM to "1", one can test a system
with MST (tiled) monitors where the GPU doesn't support some transform.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add the transform as a logical monitor parameter, both when getting the
current state and applying a new configuration. The transform is defined
to be identical to MetaMonitorTransform.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Adds a <transform> element to <logicalmonitor>. It has two possible sub
elemenst: <rotation> which can be normal, right, left or upside_down,
and <flipped> which can either be true or false.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add support for rotated monitors. This is done per logical monitor, as
every monitor assigned to a logical monitor must be transformed in the
same way. This includes being transformed on the same level; e.g. if
the backend does not support transforming any monitor of a logical
monitor natively, then all monitors will be transformed using the
offscreen intermediate framebuffer.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Always draw the stage to an offscreen framebuffer when using the nested
backend, so that we more emulate things more similarly to how it works
real-world, i.e. it'll work the way whether stage views are enabled or
not.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The CRTC position depends on the transform and how the transform is
implemented. The function calculating the positions still doesn't
support anything but the non-transformed case; this commit is in
preparation of adding support for transforms.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Keep track of the logical monitor transform. When a logical monitor is
transformed, all of its monitors are also transformed in the same way.
A logical monitor can either be transformed on the CRTC level, or using
an offscreen intermediate buffer. In both cases will the logical
monitor be transformed, but only in the latter will the view be
transformed.
MetaCrtcs::transform currently does not represent whether the CRTC is
configured to be transformed or not; only when the backend can handle
it does it correctly correspond to the actual CRTC configuration. This
is intended to change with MetaMonitorConfigManager.
https://bugzilla.gnome.org/show_bug.cgi?id=777732

Instead of using a environment variable, add a new 'experimental
feature' gsetting keyword "monitor-config-manager" that enables the use
of the new MetaMonitorConfigManager. This commit also makes it possible
to switch between the two systems without restarting mutter.
The D-Bus API is disabled when the experimental feature is not enabled,
and clients trying to access it will get a access-denied error in
response. A new property 'IsExperimentalApiEnabled' is added to let the
D-Bus client know whether it is possible to use the experimental API or
not.

The logical monitor config array ownership was transferred to the

This commit adds support for rendering onto enlarged per logical
monitor framebuffers, using the scaled clutter stage views, for HiDPI
enabled logical monitors.
This works by scaling the mode of the monitors in a logical monitors by
the scale, no longer relying on scaling the window actors and window
geometry for making windows have the correct size on HiDPI monitors.
It is disabled by default, as in automatically created configurations
will still use the old mode. This is partly because Xwayland clients
will not yet work good enough to make it feasible.
To enable, add the 'scale-monitor-framebuffer' keyword to the
org.gnome.mutter.experimental-features gsettings array.
It is still possible to specify the mode via the new D-Bus API, which
has been adapted.
The adaptations to the D-Bus API means the caller need to be aware of
how to position logical monitors on the stage grid. This depends on the
'layout-mode' property that is used (see the DisplayConfig D-Bus
documentation).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This gsetting will allow the adding of keywords to a array, where each
keyword may enable an experimental feauter, if the given mutter version
supports that particular experimental feature. Emphasis is put on the
lack of guarantee that any such keyword has any effect. Currently no
keywords are defined.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Make the concept of maximum screen size optional, as it is not
necessarily a thing on all systems (e.g. when using the native backend
and stage views).
The meta_monitor_monitor_get_limits() function is replaced by a
meta_monitor_manager_get_max_screen_size() which fails when no screen
limit is available. Callers and other users of the previous max screen
size fields are updated to deal with the fact that the limit is
optional.
The new D-Bus API is changed to move it to the properties bag, where
its absence means there is no applicable limit.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a new D-Bus API that uses the state from GetCurrentState to
configure high level monitors, instead of low level CRTCs and
connectors. So far persistent configuration is not implemented, as
writing to the configuration store is still not supported.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Logical monitors in a configuration must be adjecent to each other,
meaning there will be at least one pixel long side touching some other
logical monitor.
The exception to this is when there is only one logical monitor, which
cannot be adjecent to any other.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
We don't want to limit ourself to whole integers for configuration, as
that'd mean it wouldn't be able to provide configurations for
fractional scalings. Thus, change scales to be referred to as floats
instead of ints.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a 'is_underscanning' entry to the properties map, if the monitor
supports underscanning. The client should assume a monitor does not
support underscanning if no property was added.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a D-Bus method for getting the current monitor and logical monitor
state. Currently does not contain information about transforms or any
limitations (such as limited CRTCs and cloning).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Let the backends decide whether to just rebuild a derived state, or use
the NULL config to rebuild an empty logical state.
This also changes the expected screen size values of the no-outputs
test; as this case is actually handled now.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add support to configure the logical monitor scale. With this, it
becomes possible to override the automatically calculated scaling
number per logical monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Replace the 'scale' of an output with a vfunc on the MetaMonitorManager
class that takes a monitor and a monitor mode which calculates the
scale. On X11 this always returns 1, on KMS, the old formula is used.
On the dummy and test backends, the already configured values are
returned.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The default (calculated) scale is derived from the output, but
ultimately set via the monitor scale. This will enable config files to
override the scale. Yet to be done is handling when a scale is not
supported by a backend (i.e. the X11 backend).

In some cases the hardware cursor is invisible when Mutter is launched from the
TTY, due to drmModeSetCursor2 failing without a fallback being set.
This patch captures the return value of drmModeSetCursor2 and in case of an
error, enables the texture based fallback. It adds a `broken` state, that is
checked in should_have_hw_cursor() and
meta_cursor_renderer_native_realize_cursor_from_*() to avoid copying every
cursor into a gbm buffer when we know it will fail every single time.

Quick motions can come across as too fast (or slow) if it crosses outputs
with different scales. If this happens, rebuild the motion delta applying
the scale that applies to each logical monitor the pointer is crossing.
https://bugzilla.gnome.org/show_bug.cgi?id=778119
To allow for more natural pointer movements from relative pointer
devices (e.g. mouse, touchpad, tablet tool in relative mode, etc), scale
the relative motion from libinput with the scale of the monitor. In
effect, this means that the pointer movement is twice as fast (physical
movement vs numbers of pixels passed) as before, but it also means that
the same physical movement crosses the distance in a GUI no matter if
it is on a HiDPI monitor or not.
https://bugzilla.gnome.org/show_bug.cgi?id=778119
Clutter's evdev input backend has no support for setting double
click timeout set by gnome-settings-daemon. This results in
touchpad click events timing out on wayland, because the
default timeout value wasn't enough.
This patch moves timeout setting to mutter and removes X11
backend specific setting from clutter.
https://bugzilla.gnome.org/show_bug.cgi?id=771576
The code calculating the output scale involves calculations around pixel
and mm sizes, however we do compare post-transformation pixel sizes to
untransformed mm sizes, which breaks the DPI calculations. Fix this by
transforming back pixel sizes back to untransformed.
While we're at it, actually compare the output height to HIDPI_MIN_HEIGHT
instead of its width, it seems right according to the #define name and
comment.

When a state changed, e.g. a window went from unfullscreen to
fullscreen, always sync the window geometry, otherwise a compositor
application (e.g. gnome-shell) might end up with an unfinished window
state transition effect.
Without always syncing, the compositor plugin will see a 'size-change'
event, as a result of the state change, but if the size didn't change,
it would never see the 'size-changed' event. If an effect, for example
gnome-shell's fullscreen effect, is triggered on 'size-change' it might
rely on the actual size change to not get stuck. This commit allows it
to have this dependency.
This fixes a bug where a fullscreen effect gets "stuck" when a window
goes fullscreen without changing the window geometry.
https://bugzilla.gnome.org/show_bug.cgi?id=780292
The mitigation to avoid missing EDID blob was incorrect; the reason it
sometimes failed to read was a race between different applications all
trying to read the EDID at the same time. E.g. gnome-shell as GDM would
at the same time as the session gnome-shell try to read the EDID of the
same connector at the same time, triggering a race in the kernel,
making the blob reading ioctl occationally fail with ENOENT.
Remove this mitigation, as it didn't really mitigate anything; the race
could just as well happen when doing the actual read later.
https://bugzilla.gnome.org/show_bug.cgi?id=779837
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).

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

Split up logical monitor cration into derived (when derived from

When adding a monitor and all its outputs, don't try to set the logical
