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
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
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
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.
https://bugzilla.gnome.org/show_bug.cgi?id=781906
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
to, so lets manage it ourself.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
The caller in clutter really expects an error if fd==-1, so make
sure we set one here. Otherwise we get a nice crash in addition to
the failure to open the /sys file. Also, retry on EINTR.
https://bugzilla.gnome.org/show_bug.cgi?id=784881
With GLVND, whenever we have both Mesa's and NVIDIA's drives installed
in the system, initializing the GBM backend will always succeed,
regardless of what GPU you have on your system.
This is due to GBM's software rendering fallback.
It seems better to initialize the EGLDevice backend first, which will
fail to find a device match when given a non-NVIDIA GPU.
https://bugzilla.gnome.org/show_bug.cgi?id=784272
Wacom's display tablets typically do not have (0,0) coincident with the top
left corner of the screen. This "outbound" area must be taken into account
when setting the area or else an unexpected offset of the pointer will
occur.
https://bugzilla.gnome.org/show_bug.cgi?id=784009
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.
https://bugzilla.gnome.org/show_bug.cgi?id=784009
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.
https://bugzilla.gnome.org/show_bug.cgi?id=782032
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.
https://bugzilla.gnome.org/show_bug.cgi?id=782032
Due to the pen/eraser device separation in X11, CLUTTER_TABLET_DEVICE does
not apply there, this device type is only used in native/evdev. Checking
for CLUTTER_PEN/ERASER_DEVICE makes the left-handed mode correctly applied
on tablets.
https://bugzilla.gnome.org/show_bug.cgi?id=782027
For devices connected via HDMI (supposedly TVs) we want have a
scale factor of 1 if we are *below* the smallest 4k resolution
width (not equal or above) and do the scaling factor computation
if we are above the limit. This check was apparently wrongly
ported from gnome-settings-daemon.
Based of a patch by Caolan McNamara <caolanm@redhat.com>.
https://bugzilla.gnome.org/show_bug.cgi?id=777347
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.
https://bugzilla.gnome.org/show_bug.cgi?id=781723
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
hint of how to place the virtual monitors, and they don't tend to use
tiled monitors anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=781723
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
non-KMS backends too, so move the scale calculation to MetaMonitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Introduce MetaSettings and add the settings managed by MetaBackend into
the new object. These settings include: experimental-features and UI
scaling factor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
hotplug_mode_update is used (mostly by VMs nowadays, and
VMware has implemented it) to inform that modes list (including
the preferred one) might change after an uevent.
However, when using MetaMonitorConfigManager we should
ignore this value at initialization level, or mutter
won't restore the configured values at startup.
https://bugzilla.gnome.org/show_bug.cgi?id=783073
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.
https://bugzilla.gnome.org/show_bug.cgi?id=764852
Let the backend implementations create their own input settings
backend, as is done with other backend specific special purpose
backends. Also use the macro for declaring the GType.
https://bugzilla.gnome.org/show_bug.cgi?id=782152
meta_backend_real_post_init() had some open coded initialization with
some unexpected interdependencies. Split these up and move them to their
own functions in order to make meta_backend_real_post_init() a bit more
readable.
https://bugzilla.gnome.org/show_bug.cgi?id=782152
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
only checked if the key passed by the second argument ended up being
shorter.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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
main output of an inactive monitor doesn't have an assigned CRTC.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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
singal "ui-scaling-factor-changed" is added in order to liston for for
changes.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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
toolkit, so lets remove this unused feature.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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
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
Split up the MetaRendererX11 class into one for when running as a
X11 compositing manager, and one for when running as a nested Wayland

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.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The logical monitor config array ownership was transferred to the
config object when it was created, but was not unset when the config
verification failed, causing the clean up path for invalid configs to
try to clean up the same list again.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
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.
https://bugzilla.gnome.org/show_bug.cgi?id=770020
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.
https://bugzilla.gnome.org/show_bug.cgi?id=777687
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).
https://bugzilla.gnome.org/show_bug.cgi?id=779837
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
depends on how the configuration is done. Instead, don't set the CRTC
rect at all, and update the screen dimensions when being configured.

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.

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.
