The nested backend used the value from udev, meaning that one couldn't
configure the fake monitor if the laptop panel of the host was closed.
Avoid this annoyance by always having the nested backend claiming the
lid is open.
It wasn't implemented by any subclass, it's not provided by DRM either.
And even if a subclass were to have only a file available, it could read
it into a GBytes as well and just use `read_edid()`.
Found this while working on !269.
Because it is implemented and always on. By advertising this fact
the master clock is able to sync to the native refresh rate instead
of always using the fallback of 60.00Hz.

Add support for getting hardware presentation times from KMS (Wayland
sessions). Also implement cogl_get_clock_time which is required to compare
and judge the age of presentation timestamps.
For single monitor systems this is straightforward. For multi-monitor
systems though we have to choose a display to sync to. The compositor
already partially solves this for us in the case of only one display
updating because it will only use the subset of monitors that are
changing. In the case of multiple monitors consuming the same frame
concurrently however, we choose the fastest one (in use at the time).
Note however that we also need !73 to land in order to fully realize
multiple monitors running at full speed.
Use cogl_framebuffer_read_pixels_into_bitmap () instead of
glReadPixels () for the CPU copy path in multi-GPU support.
The cogl function employs several tricks to make the read-pixels as fast
as possible and does the y-flip as necessary. This should make the copy
more performant over all kinds of hardware.
This is expected to be used on virtual outputs (e.g. DisplayLink USB
docks and monitors) foremost, where the dumb buffer memory is just
regular system memory. If the dumb buffer memory is somehow slow, like
residing in discrete VRAM or having an unexpected caching mode, it may
be possible for the cogl function perform worse because it might do the
y-flip in-place in the dumb buffer. Hopefully that does not happen in
any practical scenario.
Calling meta_renderer_native_gles3_read_pixels () here was conceptually
wrong to begin with because it was done with the Cogl GL context of the
primary GPU, not on the GL ES 3 context of a secondary GPU. However,
due eglBindAPI being a no-op in Mesa and the glReadPixels () arguments
being compatible, it worked.
This patch adds a pixel format conversion table between DRM and Cogl
formats. It contains more formats than absolutely necessary and the
texture components field which is currently unused for completeness. See
Mutter issue #323. Making the table more complete documents better how
the pixel formats actually map so that posterity should be less likely
to be confused. This table could be shared with
shm_buffer_get_cogl_pixel_format () as well, but not with
meta_wayland_dma_buf_buffer_attach ().
On HP ProBook 4520s laptop (Mesa DRI Intel(R) Ironlake Mobile, Mesa
18.0.5), without this patch copy_shared_framebuffer_cpu () for a
DisplayLink output takes 5 seconds with a 1080p frame. Obviously that
makes Mutter and gnome-shell completely unusable. With this patch, that
function takes 13-18 ms which makes it usable if not fluent.
On Intel i7-4790 (Mesa DRI Intel(R) Haswell Desktop) machine, this patch
makes no significant difference (the copy takes 4-5 ms).
The format will be needed in a following commit in the CPU copy path
which stops hardcoding another format and starts using the format the
dumb FB was created with.
Change the callers of init_dumb_fb () to use DRM format codes. DRM and
GBM format codes are identical, but since this is about dumb buffers,
DRM formats fit better.
The header /usr/include/gbm.h installed by Mesa says:
* The FourCC format codes are taken from the drm_fourcc.h definition, and
* re-namespaced. New GBM formats must not be added, unless they are
* identical ports from drm_fourcc.
That refers to the GBM_FORMAT_* codes.
Virtual keyboard and pointer are freed on session close, but the

We were using the connector_id for the winsys_id, but different

Don't schedule redraws when being headless; there is nothing to draw so

While leaving the runtime checks in place, requiring xrandr 1.5 at build

drmModePageFlip() is guaranteed to fail for the invalid FB id 0.
Therefore it never makes sense to call this function with such argument.
Disabling a CRTC must be done with SetCrtc instead, for example.
Trying to flip to FB 0 not only fails, but it also causes Mutter to
never try page flip on this output again, using drmModeSetCrtc()
instead.
There was a race in setting next_fb_id when a secondary GPU was using
the CPU copy path. Losing this race caused the attempt to
drmModePageFlip () to FB ID 0 which is invalid and always fails. Failing
to flip causes Mutter to fall back to drmModeSetCrtc () permanently.
In meta_onscreen_native_swap_buffers_with_damage ():

- meta_onscreen_native_flip_crtc ()
- meta_gpu_kms_flip_crtc () gets called with fb_id = 0
This race was observed lost when running 'mutter --wayland' on a machine
with two outputs on Intel and one output on DisplayLink USB dock, and
wiggling around a weston-terminal window between the Intel and
DisplayLink outputs. It took from a second to a minute to trigger. For
testing with DisplayLink outputs Mutter also needed a patch to take the
DisplayLink output into use, as it would have otherwise been ignored
being a platform device rather than a PCI device.
Fix this race by first waiting for pending flips and only then
proceeding with the swap operations. This should be safe, because the
pending flips could have completed already before entering
meta_onscreen_native_swap_buffers_with_damage ().
When constructing MetaMonitorsConfig objects, store which type
of switch_config they are for (or UNKNOWN if it is not such
type of config).
Stop unconditionally setting current_switch_config to UNKNOWN when
handling monitors changed events. Instead, set it to the switch_config
type stored in the MonitorsConfig in the codepath that updates logical
state. In addition to being called in the hotplug case along the same
code flow that generates monitors changed events, this is also called
in the coldplug case where a secondary monitor was connected before
mutter was started.
When creating the default linear display config, create it as a
switch_config so that internal state gets updated to represent
linear mode when this config is used.
The previous behaviour of unconditionally resetting current_switch_config
to UNKNOWN was breaking the internal state machine for display config
switching, causing misbehaviour in gnome-shell's switchMonitor UI when
using display switch hotkeys. The lack of internal tracking when the
displays are already in the default "Join Displays" linear mode was
then causing the first display switch hotkey press to do nothing
(it would attempt to select "Join Displays" mode, but that was already
active).

meta_renderer_native_gles3_read_pixels() was assuming that the target
buffer stride == width * 4. This is not generally true. When a DRM
driver allocates a dumb buffer, it is free to choose a stride so that
the buffer can actually work on the hardware.
Record the driver chosen stride in MetaDumbBuffer, and use it in the CPU
copy path. This should fix any possible stride issues in
meta_renderer_native_gles3_read_pixels().
Track the allocated dumb buffer size in MetaDumbBuffer. Assert that the
size is as expected in copy_shared_framebuffer_cpu().
This is just to ensure that Cogl and the real size match. The size from
Cogl was used in the copy, so getting that wrong might have written
beyond the allocation.
This is a safety measure and has not been observed to happen yet.
If drmModeAddFB2() does not work, the fallback to drmModeAddFB() can
only handle a single specific format. Make sure the requested format is
that one format, and fail the operation otherwise.
This should at least makes the failure mode obvious on such old systems
where the kernel does not support AddFB2, rather than producing wrong
colors.
Previously, trackballs were detected based on the presence of the
substring "trackball" in the device name. This had the downside of
missing devices, such as the Kensington Expert Mouse, which don't have
"trackball" in their names.
Rather than depending on the device name, use the ID_INPUT_TRACKBALL
property from udev to determine whether or not to treat a device as a
trackball.
This adds a new function, `is_trackball_device`, to MetaInputEvents, and
eliminates the `meta_input_device_is_trackball` function.

The "backends: Move MetaOutput::crtc field into private struct"
accidentally changed the view transform calculation code to assume that
"MetaCrtc::transform" corresponds to the transform of the CRTC; so is
not the case yet; one must calculate the transform from the logical

meta_monitor_manager_is_transform_handled(). This commit restores the
old behaviour that doesn't use MetaCrtc::transform when calculating the
view transform.

We need a way for mutter to exit if no available GPUs are going to work.

Commit c0d9b08ef9 replaced the old GBM API calls
with the multi-plane GBM API. However, the call to gbm_bo_get_handle_for_plane
fails for some DRI drivers (in particular i915). Due to missing error checks,
the subsequent call to drmModeAddFB[2] fails and the screen output locks up.
This commit adds the missing error checks and falls back to the old GBM API
(non-planar) if necessary.
v5: test success of gbm_bo_get_handle_for_plane instead of errno
This commit adopts solution proposed by Daniel van Vugt to check the return
value of gbm_bo_get_handle_for_plane on plane 0 and fall back to old
non-planar method if the call fails. This removes the errno check (for
ENOSYS) that could abort if mesa ever sets a different value.

For historical reasons meta_monitor_is_active() checked whether it is
active by checking whether the main output have a CRTC assigned and
whether that CRTC has a current mode. At a later point, the MetaMonitor
got its own mode abstraction (MetaMonitorMode), but
meta_monitor_is_active() was never updated to use this.
An issue with checking the main output's CRTC state is that, if there is
some CRTC mode combination that for some reason isn't properly detected
by the MetaMonitorMode abstraction (e.g. some tiling configuration not
yet handled), meta_monitor_is_active() would return TRUE, even though no
(abstracted) mode was set. This would cause confusion here and there,
leading to NULL pointer dereferences due to the assumption that if a
monitor is active, it has an active mode.
Instead, change meta_monitor_is_active() to directly check the current
monitor mode, and log a warning if the main output still happen to have
a CRTC with a mode assigned to it. This way, when an not undrestood CRTC
mode combination is encountered, instead of dereferencing NULL pointers,
simply assume the monitor is not active, which means that it will not be
managed or rendered by mutter at all.

Add API to let GNOME Shell have the ability to get notified about remote
access sessions (remote desktop, remote control and screen cast), and
with a way to close them.
This is done by adding an abstraction above the remote desktop and
screen cast session objects, to avoid exposing their objects to outside
of mutter. Doing that would result in external parts holding references
to the objects, complicating their lifetimes. By using separate wrapper
objects, we avoid this issue all together.
Monitor whether UPower is running ourselves. That allows us to keep the
same value for "lid-is-closed" throughout the process of UPower
restarting, preventing unwanted monitor re-configuration through the process.
Fixes another screen black out when UPower restarts and the laptop lid
is closed.
Rather than handle UpClient in both MetaBackend (to reset the idletime
when the lid is opened), and in MetaMonitorManager and
MetaMonitorConfigManager (to turn the screen under the lid on/off
depending on its status), move the ability to get the lid status from
UPower or mock it in one place, in MetaBackend.
Restarting UPower will make every property of UpClient emit a "notify"
signal (as a GDBusProxy would). Avoid mutter reconfiguring the displays
when upower restarts by caching the last known value of "lid-is-closed"
and only reconfiguring the displays if it actually changed.
This fixes a black out of the screen when UPower restarts.
The framerate for screen cast sources was set to variable within 1 FPS
and the framerate of the monitor being screen casted. This meant that if
the sink didn't match the framerate (e.g. had a lower max framerate),
the formats would not match and a stream would not be established.
Allow letting the sink clamp the framerate range by setting it as
'unset', allowing it to be negotiated.

For some reason "backends: Remove X11 idle-monitor backend" removed
unrelated warning messages for when generated monitor configurations
that should work didn't, which also made the unit tests fail.
This commit adds them back, which also makes the tests pass again.

However, there won't be any EGL config satisfying such criteria for

This change will let us choose the first EGL config for the EGLDevice
backend, while still forcing GBM_FORMAT_XRGB8888 configs for the GBM

Where to realize a hardware cursor depends on where on the screen it
will be displayed. For example it only needs buffers for the cursor
plane on a certain GPU if it overlaps with a monitor that is connected
said GPU.
Previously, we were too eager with uploading the cursor plane buffers,
which in effect resulted in the secondary GPU always being woken up
when changing the cursor, even though the cursor plane would actually
never be set unless the pointer cursor was moved to a monitor connected
to the secondary GPU. These wake-ups caused noticable stuttering; thus
by uploading the buffers more lazilly, the stuttering is avoided.

When a cursor is hidden, the native backend will properly hide the HW

drmModeAddFB2 allows userspace to specify a real format enum on

As an optimisation, Weston used to decide at the first failure of

ioctls return -EINVAL rather than -ENOSYS or similar, bad parameters are
not distinguishable from the ioctl not being present.
Mutter has also implemented the same optimisation for dumb framebuffers,
which potentially papers over errors for the gain of avoiding one ioctl
which will rapidly fail on ancient kernels. Remove the optimisation and

As a follow up to the patch from a95cbd0a, we need to make sure

The ResetIdletime API can be used instead of an "XTest" binary to

clutter code ignores "Core Events" as generated by XTest.

Rendering the next frame (which mostly happens as part of the flush done

When using two monitors size by side with different scales, once the
cursor moves from one output to another one, its size changes based on
the scale of the given output.
Changing the size of the cursor can cause the cursor area to change
output again if the hotspot is not exactly at the top left corner of the
area, causing the texture of the cursor to change, which will trigger
another output change, so on and so forth causing continuous surface
enter/leave event which flood the clients and eventually kill them.
Change the logic to use only the actual cursor position to determine if
its on the given logical monitor, so that it remains immune to scale
changes induced by output scale differences.

We were retrieving the supported KMS modifiers for all GPUs even
though what we really need to intersect between these sets of
modifiers:
1) KMS supported modifiers for primary GPU if the GPU is used for
scanout;
2) EGL supported modifiers for secondary GPUs (different than the
primary GPU used for rendering);
3) GBM supported modifiers when creating the surface (already
taken care of by gbm_surface_create_with_modifiers());

So the changes can be instantly applied while the tool is in proximity.
Before we would just do it on proximity-in, which doesn't provide a

The property has been 32 bits since around 2011 and has not changed, mutter
expects it to be 8 bits. The mismatch causes change_property to never

There seems to be a kernel race when one disconnects an external
monitor connected to a DisplayPort via a USB-C adapter. The race
results in a connector being reported as connected, but without any
modes supported.
This had the side effect that we tried to set a preferred mode to
the first listed mode, but as no modes were available, we instead tried
to dereference the first element of a NULL array, causing a
segmentation fault.
Mitigate this by skipping adding output if no supported modes are
advertised and the output doesn't support scaling, while moving the
fallback path for calculating a preferred output mode to after possibly
adding the common modes, to avoid the unvolentary NULL dereference.

Opening and closing the device may result into XI2 grabs being cut short,
resulting into pad buttons being rendered ineffective, and other possible
misbehaviors. This is an XInput flaw that fell in the gap between XI1 and
XI2, and has no easy fix. It pays us for mixing both versions, I guess...
Work this around by keeping the XI1 XDevice attached to the
ClutterInputDevice, this way it will live long enough that this is not
a concern.
Investigation of this bug was mostly carried by Peter Hutterer, I'm just
the executing hand.

A comparison in translate_device_event() does not account for the fact
that X's clock wraps about every 49.7 days. When triggered, this causes
an unresponsive GUI.
Replace simple less-than comparison with XSERVER_TIME_IS_BEFORE macro,
which accounts for the wrapping of X's clock.

The tertiary-button-action (see bug 790028) is a place for g-c-c to store

Pressing this button is signaled as a BTN_STYLUS3 event from the kernel or

Now that we have the list of supported modifiers from the monitor
manager (via the CRTCs to the primary planes), we can use this to inform
EGL it can use those modifiers to allocate the GBM surface with. Doing
so allows us to use tiling and compression for our scanout surfaces.
This requires the Mesa commit in:
Mesa 10.3 (08264e5dad4df448e7718e782ad9077902089a07) or
Mesa 10.2.7 (55d28925e6109a4afd61f109e845a8a51bd17652).
Otherwise Mesa closes the fd behind our back and re-importing will fail.

The KMS IN_FORMATS blob property contains a structure defining which
format/modifier combinations are supported for each plane. Use this to
extract a list of acceptable modifiers to use for the primary plane for
XRGB8888, so we can ask EGL to allocate tiled/compressed buffers for
scanout when available.

Using 800x600 as minimum logical size is very 4:3 thinking, while a lot of
modern devices are 16:9. The specific reason for this commit is to allow
1.5 scaling at mini-laptops (clamshell devices) with e.g. a 5.5"
1280x720 screen. Given that this device has a keyboard, one obviously
is not holding it very close to ones eyes and at 220 dpi that means the text
is too small at scale 1.0. For one real world example of such a device see:
https://en.wikipedia.org/wiki/GPD_Winhttps://bugzilla.gnome.org/show_bug.cgi?id=792765
The device orientation coming out of iio-sensor-proxy defines upright/normal
as the direction in which the picture is displayed on the LCD panel without
any rotation. This is necessary for accelerometer rotation to work properly
in desktop environments which are not aware of panel-orientation issues.
This means that we need to correct the logical-monitor-config / user-visible
rotation for the panel-orientation when we get rotation info from
iio-sensor-proxy.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Just like we swap the x and y resolution of the monitor modes when
the panel-orientation requires 90 or 270 degree rotation to compensate,
we should do the same for the width and height in mm of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
If a monitor's max resolution is a portrait resolution, then assume it is
a native portrait monitor and add portrait versions of the common modes.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Even if the logical_monitor config does not have an active transform,
we might still be doing a transform under the hood to compensate for
panel-orientation. Check for this and fall back to the sw cursor if this
is the case.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
If a LCD panel has a non normal orientation (mounted upside-down or 90
degrees rotated) then the kernel will report touchscreen coordinates with
the origin matching the native (e.g. upside down) coordinates of the panel.
Since we transparently rotate the image on the panel to correct for the
non normal panel-orientation, we must apply the same transform to input
coordinates to keep the aligned.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Some x86 clamshell design devices use portrait tablet LCD panels while
they should use a landscape panel, resoluting in a 90 degree rotated
picture.
Newer kernels detect this and rotate the fb console in software to
compensate. These kernels also export their knowledge of the LCD panel
orientation vs the casing in a "panel orientation" drm_connector property.
This commit adds support to mutter for reading the "panel orientation"
and transparently (from a mutter consumer's pov) fixing this by applying
a (hidden) rotation transform to compensate for the panel orientation.

We only counted configured monitors and whether the config was
applicable (could be assigned), howeverwe didn't include disabled
monitors when comparing. This could caused incorrect configurations to
be applied when trying to use the previous configuration.
One scenario where this happened was one a system with one laptop
screen and one external monitor that was hot plugged some point after
start up. When the laptop lid was closed, the 'previous configuration'
being the configuration where only the laptop panel was enabled, passed
'is-complete' check as the number of configured monitors were correct,
and the configuration was applicable.
Avoid this issue by simply comparing the configuration key of the
previous configuration and the configuration key of the current state.
This correctly identifies a laptop panel with the lid closed as
inaccessible, thus doesn't incorrectly revert to the previous
configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=788915
When deriving the list of disabled monitors when creating new monitors
configs, don't include the laptop panel if the lid is currently closed,
as we consider the laptop panel nonexistent when the laptop lid is
closed when it comes to configuration.
The laptop panel connector(s) will either way be appropriately disabled
anyway, as the field listing disabled monitors in the configuration do
not affect actual CRTC/connector assignments.

Commit b1a0bf891 broke the previous logic that we would only fallback
to the root cursor if 1) windows are not interactable or 2) no window
cursor is currently set (i.e. not hovering over any window). Now it
will set up the root cursor if it's NULL, which breaks clients
explicitly setting an invisible cursor. This commit restaurates the
previous behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
This function is supposedly not failable, so just move the theme_dirty
flag clearing to the beginning of the function. Protects against cases
where requesting a cursor image may result in it being loaded and set
as a texture, which emits ::texture-changed, which may end up requesting
the cursor image again.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
As wayland implements the cursor role, it consists of a persistent
MetaCursorSprite that gets the backing texture changed. This is
inconvenient for the places using MetaCursorTracker to track cursor
changes, as they actually track MetaCursorSprites.
This signal will be used to trigger emission of
MetaCursorTracker::cursor-changed, which will make users able to
update accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=754806
Just like X11/XFixes behaves, the current cursor is not affected
by its visibility, so it can be queried while invisible (possibly
to be replaced).
For this, keep an extra effective_cursor pointer that will be
either equal to displayed_cursor (maybe a bit of a misnomer now)
or NULL if the cursor is invisible. The MetaCursorRenderer
management is tied to the former, and the ::cursor-changed signal
emission to the latter.

Bluetooth mouse usually goes in sleep state after a timeout, when that
happen the mouse is disconnected and on_device_removed function is
called. Before the patch if a touch device is available the
on_device_removed function hide the cursor. The issue is that the cursor
does not reappear once the bluetooth mouse is reconnected because
MetaBackend::current_device_id is not invalidated when on_device_removed
was called.
The patch set MetaBackend::current_device_id to 0 if the current device
is removed. This will make update_last_device to be triggered as soon as
another input device is used or the bluetooth mouse reconnect, as
consequence that the cursor reappear. The id 0 is never given to devices
and can safely used as undefine id.

Check that if there are multiple modes with the same ID (resolution,
refresh rate and handled flags) we correctly add the preferred mode to
the list of monitor modes.
https://bugzilla.gnome.org/show_bug.cgi?id=789153
When generating MetaMonitorMode's, prefer CRTC modes that has the same
set of flags as the preferred mode. This not only is probably a better
set of configurable modes, but it'll guarantee that the preferred mode
is added.
This fixes a crash when the preferred mode was not the first mode with
the same resolution, refresh rate and set of handled modes.

Under X11 we can only ever have the same scale configured on all
monitors. In order to use e.g. scale 2 when there is a HiDPI monitor
connected, we must not disallow it because there is a monitor that does
not support scale 2. Thus we must show the same scale for every monitor
and monitor mode, even though it might result in a bad experience.
Do this by iterating through all the monitors adding all supported
scales by the preferred mode, combining all the supported scales. This
supported scales list is then used for all monitor and modes no matter
what.
