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.

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.

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).

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
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
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
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
The new monitor configuration system (MetaMonitorConfigManager) aims to
replace the current MetaMonitorConfig. The main difference between the
two is that MetaMonitorConfigManager works with higher level input
(MetaMonitor, MetaMonitorMode) instead of directly looking at the CRTC
and connector state. It still produces CRTC and connector configuration
later applied by the respective backends.
Other difference the new system aims to introduce is that the
configuration system doesn't manipulate the monitor manager state; that
responsibility is left for the monitor manager to handle (it only
manages configuration and creates CRTC/connector assignments, it
doesn't apply anything).
The new configuration system allows backends to not rely on deriving the
current configuration from the CRTC/connector state, as this may no longer be
possible (i.e. when using KMS and multiple framebuffers).
The MetaMonitorConfigManager system is so far disabled by default, as
it does not yet have all the features of the old system, but eventually
it will replace MetaMonitorConfig which will at that point be removed.
This will make it possible to remove old hacks introduced due to
limitations in the old system.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The function meta_monitor_manager_read_current_config() was renamed to
meta_monitor_manager_read_current_state() as it does not read any
configuration, but reads the current state as described by the backend.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Don't deal with adding/removing tiled Xrandr monitors in the generic
backend, but leave it to the Xrandr backend. The tiled monitor will
itself notify the backend when such a monitor is added and removed.
Tiled Xrandr monitors are now based no MetaMonitor instead of
MetaLogicalMonitor. This means that mirrored tiled monitors will now be
represented correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The MetaMonitorMode referred to the mode of a CRTC, and with the future
introduction of a MetaMonitor, theh old name would be confusing.
Instead call it what it is.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
In preparation for further refactorizations, rename the MetaMonitorInfo
struct to MetaLogicalMonitor. Eventually, part of MetaLogicalMonitor
will be split into a MetaMonitor type.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
We might get modes in XRROutputInfos that aren't in the
XRRScreenResources we get earlier. This always seems to be transient,
i.e. when it happens, the X server will usually send us a follow up
RRScreenChangeNotify where we then get a "stable" view of the world
again.
In any case, when these glitches happen, we end up with NULL pointers
in the MetaOutput->modes array which makes us crash later on. This
patch ensures that doesn't happen.
https://bugzilla.gnome.org/show_bug.cgi?id=756660
We should not be setting random output properties like this.
Use the function we just introduced to only set the underscan flag when
it's actually supported.
So that clients such as the control center can decide to hide an
underscanning checkbutton when the output does not support it.
Support in the KMS / native backend to come later...
It seems that fglrx sometimes gives us absolute junk when requesting the
outputs, and if we don't trap errors, we'll just crash when trying to
configure a junk output. Use xcb so errors simply get ignored.
this just adds backend support for retrieving the tile
information from X11 (randr 1.5) and native backends.
It stores the tiling information into the output struct.
Some DRM drivers have added a consistent set of properties that
allow compensating for the overscan that some TVs do, without the
user being able to disable.
EDID parsing has been refactored to a common meta_output_parse_edid()
function, which ensures the extracted information is the same on both KMS
and X11 backend, so it can be used consistently on eg. settings values.

This reverts commit 47e339b46e. The
approach that was used to reduce the amount of work we do on RR events
to the necessary minimum is flawed. It assumes that, when the first
event we see where the retrieved XRRScreenResources.timestamp is
bigger than the previous, we already have all the data we need to
rebuild our view of the world.
That isn't true however, because the X server sends
RRScreenChangeNotify events for every step of the configuration
change, i.e. it lacks an atomic reconfiguration API. In particular, if
the X screen size is one of the changes, when we rebuild our state and
emit monitors-changed, the X screen size might still be the previous
one and since we stop updating ourselves until another reconfiguration
happens (noticed by looking at XRRScreenResources.timestamp) we end up
with the wrong idea of the X screen size.
https://bugzilla.gnome.org/show_bug.cgi?id=738630
This optimization breaks our use of XRRScreenResources' timestamps to
detect hotplugs in case one of the outputs is disconnected and the
remaining ones don't need any mode, position or transform adjustments.
In that scenario, when applying the new configuration, we resize the X
screen but never call XRRSetCrtcConfig() and since XRRSetScreenSize()
doesn't take a timestamp and the X server doesn't update its last set
timestamp, when we next get a RRScreenChangeNotify and update
ourselves, XRRScreenResources.timestamp will still be smaller than
XRRScreenResources.configTimestamp which makes us think we're seeing a
new hotplug. We just don't enter an endless loop because the screen
size that we keep applying is always the same and the X server
short-circuits and stops sending us RRScreenChangeNotifys.
Always calling XRRSetCrtcConfig() ensures that the last set timestamp
will be bigger than configTimestamp in the next event and thus making
us trigger the monitors-changed signal properly.
Note that the X server already does basically the same checks that
we're removing here, so doing this shouldn't be a significant
efficiency loss. See
http://cgit.freedesktop.org/xorg/xserver/tree/randr/rrcrtc.c?h=server-1.16-branch#n539
In recent versions of the QXL driver, it may set "suggested X|Y" connector
properties. These properties are used to indicate the position at which
multiple displays should be aligned. If all outputs have a suggested position,
the displays are arranged according to these positions, otherwise we fall back
to the default configuration.
At the moment, we trust that the driver has chosen sane values for the
suggested position.
The X server sends several RRScreenChangeNotify events in a burst when
something happens which, currently, causes us to rebuild our view of
the world as many times and notify the upper layers about it which
causes a lot of bogus repeated work like rebuilding background actors.
We can avoid this extra work by looking at the timestamp in the
XRRScreenResources struct which is updated when an X client (including
us!) last changed something and comparing it with the previous
timestamp.
