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.

Calling queue_redraw() in _force_update() is not needed because
update_cursor() will do this when needed, i.e. when switching between
hardware cursor and texture cursor, or when drawing with texture cursor.
There is also no need to force _native_force_update() because
update_cursor() will cover this as well when needed. When not changing
cursor but only the gbm_bo, the "dirty" boolean on the gbm_bo will
trigger a redraw.

This commits refactors cursor handling code and plugs in logic so that
cursor sprites changes appearance as it moves across the screen.
Renderers are adapted to handle the necessary functionality.
The logic for changing the cursor sprite appearance is done outside of
MetaCursorSprite, and actually where depends on what type of cursor it
is. In mutter we now have two types of cursors that may have their
appearance changed:
- Themed cursors (aka root cursors)
- wl_surface cursors
Themed cursors are created by MetaScreen and when created, when
applicable(*), it will extend the cursor via connecting to a signal
which is emitted everytime the cursor is moved. The signal handler will
calculate the expected scale given the monitor it is on and reload the
theme in a correct size when needed.
wl_surface cursors are created when a wl_surface is assigned the
"cursor" role, i.e. when a client calls wl_pointer.set_cursor. A
cursor role object is created which is connected to the cursor object
by the position signal, and will set a correct texture scale given what
monitor the cursor is on and what scale the wl_surface's active buffer
is in. It will also push new buffers to the same to the cursor object
when new ones are committed to the surface.
This commit also makes texture loading lazy, since the renderer doesn't
calculate a rectangle when the cursor position changes.
The native backend is refactored to be triple-buffered; see the comment
in meta-cursor-renderer-native.c for further explanations.
* when we are running as a Wayland compositor
https://bugzilla.gnome.org/show_bug.cgi?id=744932
Use a specialized cursor renderer when running as a nested Wayand
compositor. This new renderer sets an empty X11 cursor and draws the
cursor as part of the stage using the generic cursor renderer drawing
path.
https://bugzilla.gnome.org/show_bug.cgi?id=744932
This fixes build error caused by commit 614d6bd. We can simply remove
the usage of meta-wayland.c functions in non-wayland build because

If the user Alt-Tabs out of the window, we will be left thinking
the Alt key is still pressed since we don't see a release for it.
Solve this and other related issues for the nested X11 compositor
by selecting for KeymapStateMask which causes a KeymapNotify event
to be sent after each FocusIn, and when we get these events, update
the internal XKB state and send any necessary modifiers events to
clients.
https://bugzilla.gnome.org/show_bug.cgi?id=753948
There were lots of code handling the native renderer specific cases;
move these parts to the renderer. Note that this causes the X11 case to
always generate the texture which is a waste of memory, but his
regression will be fixed in a following commit.
The lazy loading of the texture was removed because it was eventually
always loaded anyway indirectly by the renderer to calculate the
current rect.

Before, it used to be in the screen, but now,
meta_cursor_reference_from_theme can never fail. Move it to where we
load the images from the cursor name.
Since mutter has two X connections and does damage handling on the
frontend while fence triggering is done on the backend, we have a race
between XDamageSubtract() and XSyncFenceTrigger() causing missed
redraws in the GL_EXT_X11_sync_object path.
If the fence trigger gets processed first by the server, any client
drawing that happens between that and the damage subtract being
processed and is completely contained in the last damage event box
that mutter got, won't be included in the current frame nor will it
cause a new damage event.
A simple fix for this would be XSync()ing on the frontend connection
after doing all the damage subtracts but that would add a round trip
on every frame again which defeats the asynchronous design of X
fences.
Instead, if we move fence handling to the frontend we automatically
get the right ordering between damage subtracts and fence triggers.

While we shouldn't normally receive crossing events for any windows
except the stage when running nested, we do in case we hold a pointer
grab - just ignore those events instead of taking down the user's
session.
If GL advertises this extension we'll use it to synchronize X with GL
rendering instead of relying on the XSync() behavior with open source
drivers.
Some driver bugs were uncovered while working on this so if we have
had to reboot the ring a few times, something is probably wrong and
we're likely to just make things worse by continuing to try. Let's
err on the side of caution, disable ourselves and fallback to the
XSync() path in the compositor.

Some monitors return a bunch of bytes on their display descriptor

Before submitting a new scroll mode, click method or sendevents mode check if
the value is supported by the device. This avoids BadValue errors when setting

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.
For enter / leave events, which we use in the UI code, we need to make
sure that these coordinates are root-relative as well, otherwise the
cursor when entering frames might be incorrect.
If we're running as a nested compositor, we must not attempt to
passive grab on the root window, and we should be setting the
touch event mask on the stage window.
https://bugzilla.gnome.org/show_bug.cgi?id=751036
This way, we won't be hit with BadValue errors if we set it to a value
outside the X device's range. This can happen for touchpads without
two-finger scrolling, for instance.
Instead of selecting the first drm mode as the preferred mode, select the

The monitors info structure is created from the tiled outputs
and this is used as the central storage for info about a monitor
as opposed to the output state.
It appears at least the EDID mm w/h is for the whole monitor and
not per tile.
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.
This makes gnome-settings-daemon turn on the backlight and
gnome-shell's screen shield animate.
Note that on X sessions, gnome-settings-daemon uses the same upower
property to force an innocuous key event into the X server so that the
idle time gets reset since Xorg doesn't do this itself on lid events.

We'll need to get the value of some properties. Fail if the number of

Some DRM drivers have added a consistent set of properties that
allow compensating for the overscan that some TVs do, without the

This seems nicer/tidier than the current X11 (center on the span of all

clutter currently never emits activated or deactivated signals on
the stage object when using the EGL backend. Since the stage never
gets activated, accessibility tools, like orca, don't work.
This commit makes mutter take on the responsibility, by tracking
when the stage gains/loses focus, and then synthesizing stage
CLUTTER_STAGE_STATE_ACTIVATED state events.
A limitation of this approach is that clutter's own notion of
the stage activeness won't reflect mutter's notion of the
stage activeness. This isn't a problem, in practice, and can
be addressed in the medium-term after making changes to
clutter.

On startup, the cursor is kept hidden if there's any touchscreen available.
If the device that was last interacted is removed, we check on available
pointing devices though, so we don't possibly hide the pointer if there are
further mice/touchpads/etc.
Devices being added don't update cursor visibility, we wait for the user
interacting with those instead.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
On X11, calling this function on meta_display_handle_events() will not catch
mouse events happening over clients, so poke directly in the backend for
XI_DeviceChanged events, which mutter will get on device switches.
The code has been slightly refactored so we deal with XIEvents at a single
handle_input_event() function.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
This function can be used to trigger changes depending on the device type
that is currently emitting the events. So far, it is used to switch cursor
visibility on/off on touchscreen interaction.
A "last-device-updated" signal has also been added, in order allow hooking
other behavior changes (eg. OSK) when the last device changes.

Otherwise the pointer might be "lost" outside the visible area. Note
that the constraining code only ensures the pointer doesn't leave the
visible area but if the pointer is already outside because the rug was
pulled under it then it doesn't do anything.

For each device that can be mapped (touchscreens, tablets), the output
will be fetched from settings and matched with the currently connected
ones. If a match is found, the device matrix will be found out from the

collectively on output configuration changes.

This object internally keeps track of the relevant input configuration,
and goes through its vmethods in order to apply the configuration on the
backend-specific devices.
So far, only mouse/touchpad settings are actually attached to GSettings
changes. ::set_matrix(), meant for tablets/touchscreens, is not hooked
yet.
One caveat is that meta_input_settings_create() may return NULL if the
backend does not own the windowing system (wayland nested on X11 being
the one case), and thus device settings can't be changed freely.

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
It doesn't make sense to load cursor textures that we might not ever
use. Since the code here also uses CoglTexture2D, and cursors tend
to be NPOT textures, then we won't crash users of cards without
NPOT support. At least until they open the magnifier. :)
Refactor make_default_config() to always sanity-check the configuration to
ensure that it fits within the framebuffer. Previously, this was only done
for the default linear configuration.
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.
When the output device has hotplug_mode_update (e.g. the qxl driver used in
vms), the displays can be dynamically resized, so the current display
configuration does not often match a stored configuration. When a new
monitor is added, make_default_config() tries to create a new display
configuration by choosing a stored configuration with N-1 monitors, and then
adding a new monitor to the end of the layout. Because the stored config
doesn't match the current outputs, apply_configuration() will routinely
fail, leaving the additional display unconfigured. In this case, it's more
useful to just fall back to creating a new default configuration from
scratch so that all outputs get configured to their preferred mode.
Move logic for creating different types of configurations into separate
functions. This keeps things a bit cleaner and allows us to add alternate
configuration types more easily.
When a laptop's lid is closed we try to build and apply a temporary
configuration that disables the laptop's display if we have other
outputs.
This isn't enough though, we must also check if at least one of these
other outputs is enabled otherwise we'll try to resize the screen to
0x0 which (rightfully) hits an assertion.
https://bugzilla.gnome.org/show_bug.cgi?id=739450
It turns out that this was wrong because MetaWindow->monitor points to
the old monitor infos and they are needed to position windows in the
new configuration which happens in a monitors-changed handler.
This reverts commit e1704acda4.
The code in MetaMonitorConfig was really complex and was trying to do
way too much, using multiple different variables to determine where
things were stored, and trying to do fancy tricks to transfer
ownership.
Add a refcounting system to help simplify this, and clean up the logic.
Simply along the way, this fixes multiple bugs in the monitor config
logic, most notably bug #734889, which was my original goal to fix.
