The elementary guys would like this as an API, and I don't see any
reason to refuse -- this is quite nice shadow painting code :)
For some reason, gobject-introspection can't seem to cope with
MetaWindowShape. I'll look into it a bit later, but for now, mark
the function it has trouble with as (skip).
It seems that when translated, paint_offset and actor_offset will always
be the same, so our translation of the clip group won't work. For now,
until I figure out what's going on here, just use the painting offset,
since that what seems to make sense to me.
I didn't write this code, though, so I don't know why the actor's
allocation was involved in this computation at all.
I tested briefly with clones (magnifier, manual cloning through the
looking glass) and couldn't find any other artifacts, so I'm going to do
this for now.
A much less hacky version of maximize / unmaximize is reimplemented
in terms of this, but it could also eventually be used for fullscreen /
unfullscreen, and tile / untile.
The comment explains it better, but Clutter tries to be smart and
repaint actors when their allocations change. Since the window group's
allocation changes when windows move around, this means that moving a
window will always cause a full-stage repaint, which is super slow.
Hack around this for now.
While nothing will completely fix X11's artifacts, this tends to look a
bit better, *especially* with mask textures that have black at the
edges (which are most of them).
It's also faster for GPUs to manage.
The only time we ever execute this code is when we're minimizing or
hiding a window, in which case we should respect stacking order.
This fixes weird "bugs" where windows from the same app magically pop up
over other windows.
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...
This is an extremely niche feature, and conflicts with the rest of our
interface being consistent about not allowing resizing while tiled or
maximized.
A window may be hidden even if not minimized itself, for instance
when an ancestor is minimized. As meta_window_focus() will refuse
to actually focus the window in that case, don't pick it in the first
place.

Firstly, this patch makes MetawaylandDataSource a GObject. This is in
order to easier track its lifetime without adding destroy signals etc. It
also makes the vfunc table GObject class functions instead while at it,
as well as moves protocol specific part of the source into their own
implementations.
An important part of this patch is the change of ownership. Prior to this
patch, MetaWaylandDataDevice would kind of own the source, but for
Wayland sources it would remove it if the corresponding wl_resource was
destroyed. For XWayland clients it would own it completely, and only
remove it if the source was replaced.
This patch changes so that the protocol implementation owns the source.
For Wayland sources, the wl_resource owns the source, and the
MetaWaylandDataDevice sets a weak reference (so in other words, no
semantical changes really). For XWayland sources, the source is owned by
the selection bridge, and not removed until replaced or if the client
goes away.
Given the changes in ownership, data offers may now properly track the
lifetime of a source it represents. Prior to this patch, if an offer with
an XWayland source would loose its source, it wouldn't get notified and
have an invalid pointer it would potentally crash on. For Wayland
sources, an offer would have a weak reference and clean itself up if the
source went away. This patch changes so the behavior is consistent,
meaning a weak reference is added to the source GObject so that the offer
can behave correctly both for Wayland sources and XWayland sources.

When a possible drag dest client crashes during DnD, it may happen
we receive first the destroy notification for the data_device, and
later the notification for the focus surface. When this happens we
unset the drag_focus_data_device first, and later on
meta_wayland_drag_grab_set_focus(grab, NULL) we assume it still
exists when sending the leave event, leading to mutter crashing
right after.
So, as we don't receive any ordering guarantees about resource
destruction, just prepare the meta_wayland_drag_grab_set_focus()
paths for this.
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.
Going from fullscreen to unfullscreen involves a frame border size, so
in order to properly interpret the saved rect size, we need to make sure
that the frame borders are fully up to date.
When we're unredirected, we don't have a pixmap, and thus our allocation
becomes 0x0. So when events come in, they pass right through our actor,
going to the one underneath in the stack.
Fix this by having a fallback size on the shaped texture actor when
we're unredirected, causing it to always have a valid allocation.
This fixes clicking on stuff in sloppy / mouse mode focus.
In commit cc5def1, buttons were changed from GdkRectangles to
MetaButtonSpace units, but the corresponding memset hack was not.
This means that the clickable portion of the unshade rectangle
was always set to uninitalized memory. The effects of this were
random, but in cases where the moon is aligned just right, the
rectangle would graze over the borders, and so it would take priority
over other borders and show a pointer cursor instead of a resize
cursor.
Since we're using xcb now, not Xlib, it doesn't have the stupid silly
thing where it copies all 32-bit data to 64-bit data to match the
long-y-ness of it.
It seems the largest possible value is to be passed, so actually pass
that instead. Note that even though the name of the xcb_get_property
parameter is called 'long_length' its actually a uint32_t.

Mutter generates a motion event for every button and scroll events,
which confuses Xwayland apps that rely on XMotionEvents for various

According to the xdg-shell protocol specification the (x, y) coordinates

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.
When DnD is started from an X11 client, mutter now sets up an special
grab that 1) Ensures the drag source keeps receiving events, and 2)
Moves an internal X Window over wayland clients as soon as the pointer
enters over these.
That window will act as the X-side peer for the currently focused
wayland client, and will transform XdndEnter/Position/Leave/Drop
messages into wayland actions. If DnD happens between X11 clients,
the window will be moved away and unmapped, to let these operate as
usual.
https://bugzilla.gnome.org/show_bug.cgi?id=738312
X11 client windows now hook a X11-specific MetaWaylandDragDestFuncs
that converts these into Xdnd* messages, and an additional selection
bridge has been added to take care of XdndSelection, and the data
transfers done through it.

This will be useful in order to interact with drag dest surfaces in

window->is_alive isn't initialized explicitly so it defaults to FALSE
meaning that if the first ping fails we'd short circuit and not show
the delete dialog as we should.
We could initialize the variable to TRUE but in fact we don't even
need the variable at all since our dialog management is enough to
manage all the state we need, i.e. we're only interested in knowing
whether we're already displaying a delete dialog.
This does change our behavior here since previously we wouldn't
display the dialog again if the next ping failed after the dialog is
dismissed but this was arguably a bug too since in that case there
wouldn't be a way to kill the window after waiting for a while and the
window kept being unresponsive.

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

This piece of code hooks in both wl_data_device and the relevant X
selection events, an X11 Window is set up so it can act as the clipboard
owner when any wayland client owns the selection, reacting to
SelectionRequest events, and returning the data from the wayland client
FD to any X11 requestor through X properties.
In the opposite direction, SelectionNotify messages are received,
which results in the property contents being converted then written
into the wayland requestor's FD.
This code also takes care of the handling incremental transfers through
the INCR property type, reading/writing data chunk by chunk.
https://bugzilla.gnome.org/show_bug.cgi?id=738312
Expose it partly (in internal headers anyway), and pass a vtable for the
data source functions, the wayland vfuncs just delegate operations on the
wl_data_source resource. The resource has been also made optional, although
it'll be present on all data sources from wayland clients.
The ownership/lifetime of the DnD data source has also changed a bit,
belonging now to the MetaWaylandDataDevice like the selection one does, as
we can't guarantee how long it will be needed after the grab is finished,
it will be left inert and replaced the next time DnD is started at worst.
This allows the creation of custom/proxy data sources, which will turn out
useful for X11 selection interoperation.
https://bugzilla.gnome.org/show_bug.cgi?id=738312
We'll need to get the value of some properties. Fail if the number of
items returned is less than we expect and warn if it exceeds it so
that we can easily find out if items are added to a property later and
fix it.
The corresponding wl_notify field for destroy_data_device_icon()
is drag_grab->drag_icon_listener, otherwise we're fetching a pointer
that's slightly off where we want.
When running as an X11 compositor we do this for every event we see on
the X event stream. As a wayland compositor we don't go through that
code path but since we see all events we can easily do this on motion
events.
In fact, we don't even need this caching when we're a wayland
compositor since we can always find where the pointer is without a
round trip but we're sharing the current monitor logic with the X
path so let's keep it as is for now.

Add set_modal ond unset_modal to the gtk_surface interface. When a

When a parent of a subsurface gets it state applied (either by a

of the subsurface should be applied. If the subsurface is in effective

its parent surfaces is a subsurface in explicit synchronized mode), the

Since the frame is the window that's redirected, there's no reason for
it to match the root window. There *is*, however, a big incentive to
match the window's visual, since not doing so might trigger automatic
redirection.
On a specific platform, we construct a depth-32 root window, and stick a
depth-24 child window inside it. The frame ends up being created
depth-32, not depth-24, so we get automatic redirection.
since commit 8c16ac47c1, we started
creating the login screen on display 1024 instead of display 0.
This defeats this logic in try_display:
display++;
/* If display is above 50, then something's wrong. Just
* abort in this case. */
if (display > 50)
In practice it doesn't matter much since we only have one login
screen in most setups, but we should still fix the bug.
This commit introduces a separate counter to keep try of 50 tries,
rather than assuming "display number == number of tries".

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.

With all input events being handled through clutter, this only confuses

The timer to blacklist the window from frame sync is set at the time of

This means that if the client is slowly catching up, the timeout would

The wayland seat event handlers get sent events that

hardware devices the seat doesn't support and events for

This commit makes sure all uninteresting events get ignored.
Kerbel Space Program, and perhaps some other SDL-based programs, use
a really dumb way of specifying icons, which is totally
non-standards-compliant.
The ICCCM specifies that the icon_pixmap field of WM_HINTS should be a
1-bit-deep Pixmap, but we've seen applications set it to a pixmap of the
root depth as well, so we support that.
Kerbel Space Program seems to use it with a 32-bit depth Pixmap,
signifying ARGB32 (which it is), along with a 1-bit icon_mask, which
crashes us.
Keep in mind that Pixmaps, by definition, have no Visual attached, so
we simply have to make a guess at the correct visual based on the
depth. Do that by assuming that a depth-32 visual always means ARGB32,
which is a pretty safe bet.

The current ordering updates the clip shape of the composite overlay
window after unredirecting the target window. This has the effect of
forcing X to clear the target window and sending an expose to the
application to repaint - causing an unsightly flash. If we update the
shape first, then unredirect, X restores the background of the root
window (sending no expose events as no one is interested) and the
background is typically NONE for the root window. Then the unredirect
paints the contents of the composite backing pixmap over top without
requiring a round trip and waiting for the client to repaint - thus no
flashing.

When looking for space to place a new window, other non-minimized
windows on the same workspace should be taken into account. However
the current check does not work correctly when the placed window is
located on all workspaces, so handle that case explicitly.

When running as a dispay server pointer barriers are a server side
feature and requires no client interaction of any sort. This patch
implements pointer barriers that can be used when running as a display
server on the native backend. Running as a display server using the X11
backend is currently not supported.
https://bugzilla.gnome.org/show_bug.cgi?id=706655
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
output configuration and set on the device.
This is also updated both individually for newly connected devices, and
collectively on output configuration changes.
https://bugzilla.gnome.org/show_bug.cgi?id=739397
This goes through modifying XI2 device properties, either common ones (eg.
set on every device) or those specific to the libinput X11 driver. Keyboard
repeat/rate are set through core and XKB APIs.
https://bugzilla.gnome.org/show_bug.cgi?id=739397
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.
https://bugzilla.gnome.org/show_bug.cgi?id=739397
This patch removes the X11 specific code from MetaBarrier and creates an
abstraction layer MetaBarrierImpl. The existing X11 implementation is
moved to a new GObject MetaBarrierImplX11 implementing the abstract
interface MetaBarrierImpl which is instantiated by MetaBarrier when
supported.
While at it, move it to backends/ and properly name the files.
https://bugzilla.gnome.org/show_bug.cgi?id=706655
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.

MetaKeyCombo is about the *unresolved* keybinding, which can either be a
"keysym" (<Ctrl>F) or a "keycode" (<Ctrl>0x21). When we resolved the
keysym to a keycode, we stuffed it back in the same MetaKeyCombo, which
confused about what the "keycode" field was for. Thus, we often stomped
on the user's explicit choice if they chose a keycode binding value.
To solve this, create a separate structure, the "devirtualized key combo"
or MetaKeyDevirtCombo, which contains a resolved keycode from the
keysym, and a devirtualized modifier mask. The MetaKeyCombo is now
always a "source" value, and the MetaKeyDevirtCombo is now always what
the user chose.
This also lets us significantly clean up the overlay and ISO key binding
paths.
The reason MetaKeyCombo has a keycode value at all is *not* to store the
devirtualized keycode from the keysym, but instead to allow people that
type in "0x55" into the preference. Everything except the overlay-key
respected this. Make the overlay-key binding respect this.
Break down the beautiful core/ui abstraction barrier by inserting
a pointer to MetaWindow into a MetaUIFrame. I'm a scoundrel, I know.
We'll use this very soon to destroy meta_core_get.
Whenever we added a frame to the GHashTable, we added the frame itself
as the value, and a pointer to its storage of the frame window XID,
as the key.
When we iterated over the hash table, we actually looked up the
MetaUIFrame in the key, which might seem extraordinarily wrong, but
eagle-eyed viewers might notice that the XID is the first field in
MetaUIFrame, so the key and value are actually the same pointer.
Changing the layout of MetaUIFrame at all causes this to go haywire,
so let's not do this and simply put the MetaUIFrame in the value,
as expected.
When the frame type updates, we were doing something funky that
caused us to reset the title used for the text layout here. I can't
really think of any place that it would trigger, and in testing I
haven't hit this either, so let's just remove the fancy logic and
assert this.
With support for the old metacity theme format gone, there's no
reason to keep storing theme information in terms of the old theme
properties. Just store the padding/border information for each
element directly.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
MetaFrameStyle now only holds a MetaFrameLayout, so we can cut out
the middle man and use the layout directly. And as we are already
using a single style/layout per frame set and handle frame state
and focus by setting appropriate style flags, MetaFrameStyleSet
is pointless too - just store one MetaFrameLayout per frame type
directly in the theme.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Rest in peace you magnificent format, love-child of arcane X11 drawing
API and markup craze, you will not be missed.
We do remember however the bravery of a many men and women, who fearlessly
descended into the guts of your intrinsics and turned ugliness into beauty;
their work will still be spoken of when you will long have been forgotten.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
All geometry/drawing information is now picked up from the GTK+ theme,
so replace the remaining bits (hide_buttons + title_scale) with
hardcoded values from the default Adwaita theme and stop loading
the metacity theme altogether.
If there is a need to theme those constants again in the future,
we should make them available from GTK+ where they are available
for client-side decorations as well. They certainly don't justify
maintaining support for a complex theme format.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Few themes ever had support for those in the first place, and even
less supported them properly; in particular support in the default
theme has been broken for a while now.
With this in mind (and considering that not even the tweak tool exposes
any UI to configure them), let's (try to) remove support altogether - the
corresponding rects are still kept around, so it's easy to add back in
case we reconsider (and get the necessary artwork).
https://bugzilla.gnome.org/show_bug.cgi?id=741917
GTK+ doesn't deal with different frame types for its client-side
decorations - it just treats dialogs the same as normal windows
and ignores the odder frame types like UTILITY and MENU. That's
fine as those have largely gone out of fashion anyway, but it's a
different case for the WM - we still have to support them somehow.
For now, just apply the existing title_scale factor to the geometry
information picked up from the theme in addition to the title font.
If it turns out that there's demand for something more sophisticated,
we can still consider adding wm-only style information to the GTK+
theme.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
The frame shape is relevant in three places:
- the window decoration we draw
- the frame mask (used for the shape region)
- the frame bounds (used for clipping)
All three should match, so make sure to use the same GTK+ method for
the first two, and bring the (non-antialiased) third closer to the
other two by removing an obscure modifier from the corner radius.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
We now have everything in place to pick up geometry and drawing
information from GTK+ rather than the metacity theme, so do just
that; the metacity theme is now only used for some constants
(title_scale, hide_buttons, ...), which we will replace soon.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
We want to eventually pick up all theme information from GTK+ instead
of our own theme format; to prepare for this, add another helper method
to fill in geometry information from the GTK+ theme.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
GTK+ expresses the window state as style classes and widget state for
client-side decorations. Add a helper method to translate our own frame
state to the corresponding changes to the style context hierarchy.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Sounds obvious, doesn't it?
After this change when titlebar-uses-system-font is set, the "system
font" used will not be a generic one, but match what GTK+ uses in
client-side decorations.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
In order to pick up all theme information from GTK+, a single style
context is not enough; a style hierarchy that closely matches the widget
hierarchy by GTK+'s client-side decorations will allow this soon.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Our current use of style contexts is fairly limited - we don't
use them for much more than picking up some color information.
We will soon start to make more elaborate use of GTK style
information, but a single context will no longer be enough
to draw a frame then.
To prepare for this, add a simple ref-counted type to wrap
style information.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Rather than defining the space to the left and right of buttons, add a
simple spacing property that defines the space between buttons, which is
what GTK+ does for client-side decorations (e.g. GtkButtons in a GtkBox).
Unfortunately the value is hardcoded in GTK+; if it is exposed in the
theme in the future, we should pick it up from there, but for now we
just use the same value as GTK+.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Basically it's odd to have "button_rect" be a function with all the
foo_rect GdkRectangles around - renaming to get_button_rect() will
free the name for the generically named "rect" once buttons are the
only movable pieces in the frame.

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
If the app finished multiple frames before we sent _NET_WM_FRAME_DRAWN,
we could add the send_frame_messages_timer multiple times. In the rare
case that the app immediately closed the window, the older timeout
could potentially then run on the freed actor.
https://bugzilla.gnome.org/show_bug.cgi?id=738686
* Use -1 rather than 0 as a flag for pending queue entries; 0 is
a valid frame_counter value from Cogl.
* Consistently handle the fact we can have more than one pending
entry. It's app misbehavior to submit a new frame before
_NET_WM_FRAME_DRAWN is received; but we accept such frame messages,
so we can't just leak them.
* If we remove send_frame_message_timer, assign the current frame counter
to pending entries.
* To try to avoid regressing on this, when sending _NET_WM_FRAME_TIMINGS
messages, if we have stale messages, or messages with no frame drawn
time, warn and remove them from the queue rather than just accumulating.
* Improve commenting.

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. :)
Whenever the compositor takes a grab, we're supposed send leave/enter
events to the current surface, which makes sense, as the compositor
has stolen the pointer from the client.
I forget why I added the special case in the first place, but it's
likely a bug that's since been fixed.
This actually fixes a bug: it prevents the need to double-click on
X11 application titlebars when grabbing them.
Windows that set empty input shapes get n_rects of 0 when querying them
later, which makes sense, but the code that interpreted the result
translated it into a NULL input shape, which meant it was the same as
the bounding region. As such, an empty input shape would actually get
interpreted as a full input shape!
We, ourselves, set an empty input shape on tray icon windows in
gnome-shell since we would handle the picking ourselves. This meant that
we'd actually get the MetaSurfaceActorX11 when hovering over the tray
icon, instead of the ShellGTKEmbed that we capture events on and react
to.
This fixes weird tray icon behavior in gnome-shell.
The parent pick() implementation in ClutterActor only recurses if the
vfunc is untouched, which means it's up to the MetaWaylandSurface
implementation to actually recurse, just the same as if an input mask
applied.

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.
WindowActors can outlive their corresponding window to animate unmap.
Unredirecting the actor does not make sense in that case, so make
sure to not request it.

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.
