The X server frequently deals with SIGIO and SIGALRM interruptions.
If process execution is inside certain blocking system calls
when these signals arrive, e.g. with the kernel blocked on
a contended semaphore, the system calls will be interrupted.
Some system calls are automatically restartable (the kernel re-executes
them with the same parameters once the signal handler returns) but
only if the signal handler allows it.
Set SA_RESTART on the signal handlers to enable this convenient
behaviour.

Commit 2172714c changed behavior of capability handling, but it only
solved part of the problem. If Xwayland is launched without a capability
(e.g. no pointer device is connected when Xwayland was spinned up), and
later that capability comes, the device added will not be automatically
initialized. This patch initializes the device when the capability is
reported for the first time, thus avoiding the problem.

we need to pass on to the next layer to make sure the device is initialized

we try to clean up behind us.

This was built as a hack for simple Wayland compositors like Weston
which were lazy and didn't want to configure windows server-side when
moved.
Since comboboxes and menus are separate toplevel O-R windows, this hack
breaks input as it needs to be traced normally, not simply sent to the
focused window.
X11 toolkits really do need their windows to be configured correctly
for their O-R windows comboboxes or menus other things, so let's fix
the lazy compositors and remove this.
I have tested this patch with both Weston and Mutter and neither of
them require any changes, and it fixes comboboxes and menus.
If somebody then wants to revert 73698d4, that's fine by me, so we

A user on a nouveau-driven card ran into a problem where DVI-D-1 and
DVI-I-1 were aliasing. The simplest fix is to provide the full connector
names. While we're at it, rename the output names to match what is in
the kernel, and start counting the connectors from 1 rather than 0. The
only deviation is HDMI vs HDMI-A, which kept its original name.
This will break backwards compatibility with existing xorg.conf's that
reference output names, but the alternative is to create a separate
counting system, further disconnecting from the kernel names.

This patch works by using the MAXCLIENTS (raised to 512) as the maximum
allowed number of clients, but allowing the actual limit to be set by the
user to a lower value (keeping the default of 256).
There is a limit size of 29 bits to be used to store both the client ID and

When it allocates the shared pixmap it allocates it rotated,

Previously, ms_flush_drm_events() returned a boolean value, and it was
very easy to interpret the meaning incorrectly. Now, we return an
integer value.
The possible outcomes of this call are:
- poll() raised an error (formerly TRUE, now -1 - poll's return value)
- poll() said there are no events (formerly TRUE, now 0).
- drmHandleEvent() raised an error (formerly FALSE, now the negative
value returned by drmHandleEvent).
- An event was successfully handled (formerly TRUE, now 1).
The nice part is that this allows you to distinguish errors (< 0),
nothing to do (= 0), and success (1). We no longer conflate errors
with success.
v2: Change ms_present_queue_vblank to < 0 instead of <= 0, fixing an

those signals in a directed manner right now. Therefore, dbus-daemon
bypasses the broadcast matches.
However, this is not ABI and Xorg should not rely on this. systemd-logind
is free to send those signals as broadcasts, in which case Xorg will
freeze the VT. Fix this by always installing those matches.

This means that currently e.g. "startx -- vt7" breaks, and breaks badly,
requiring ssh access to the system to kill X.
The fix for this is easy, we must not use systemd-logind integration when
not using KeepTty, or iow we may only use systemd-logind integration together
with KeepTty.

linux_parse_vt_settings() was split out of xf86OpenConsole so that it can
be called earlier during systemd-logind init, but it is possible to run
the xserver in such a way that xf86OpenConsole() is never used.
The FatalError calls in linux_parse_vt_settings() may stop the Xorg xserver
from working when e.g. no /dev/tty0 is present in such a setup.
This commit adds a may_fail parameter to linux_parse_vt_settings() which
can be used to make linux_parse_vt_settings() fail silenty with an error
return in this case, rather then calling FatalError().

systemd-logind integration does not work when starting X on a new tty, as
that detaches X from the current session and after hat systemd-logind revokes
all rights on any already open fds and refuses to open new fds for X.
This means that currently e.g. "startx -- vt7" breaks, and breaks badly,
requiring ssh access to the system to kill X.
The fix for this is easy, we must not use systemd-logind integration when
not using KeepTty, or iow we may only use systemd-logind integration together
with KeepTty.
But the final KeepTty value is not known until the code to chose which vtno to
run on has been called, which currently happens after intializing
systemd-logind.
This commit is step 1 in fixing the "startx -- vt7" breakage, it factors out
the linux xf86OpenConsole bits which set xf86Info.vtno and keepTty so that
these can be called earlier. Calling this earlier is safe as this code has
no side effects other than setting xf86Info.vtno and keepTty.
Note this basically only moves a large chunk of xf86OpenConsole() into
linux_parse_vt_settings() without changing a single line of it, this is
hard to see in the diff because the identation level has changed.

In some extreme cases with animated cursors at a high frame rate we
could end up filling the wl_display outgoing buffer and end up with
wl_display_flush() failing.
In any case, using the frame callback to throttle ourselves is the
right thing to do.

Right now if "-auth" isn't passed on the command line, we let
any user on the system connect to the Xwayland server.
That's clearly suboptimal, given Xwayland is generally designed
to be used by one user at a time.
This commit changes the behavior, so only the user who started the
X server can connect clients to it.

Xwayland currently allows wide-open access to the X sockets
it listens on, ignoring Xauth access control.
This commit makes sure to enable access control on the sockets,
so one user can't snoop on another user's X-over-wayland

If present, access the unaccelerated valuator mask values for DGA and XI2 raw

Allows a mask to carry both accelerated and unaccelerated motion at the same
time.
This is required for xf86-input-libinput where the pointer acceleration
happens in libinput already, but parts of the server, specifically raw events
and DGA rely on device-specific unaccelerated data.
To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.
Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.
The server has a shortcut for changing a mask with the
valuator_mask_drop_unaccelerated() call. This saves us from having to loop
through all valuators on every event, we can just drop the bits we know we
don't want.

The image is created in the native byte order of the machine Xephyr is

Correct byte order in the xcb_image_t structure and convert to native
before updating the window.
If depths of Xephyr and host server differ this is already taken care of
by the depth conversion routine.
It is a terrible wase to always convert and transmit the entire image
no matter of the size of the damaged area. One should probably use
sub-images here. For now we leave this as an exercise.

So only return when the drmModeSetCursor2 succeeds (i.e returns 0) and disable

It uses the same option name as nvidia and the other DDXes to

v2: address two issues with DeleteUnusedDP12 enabled, reported
by Daniel Martin,
a) check we have a mode_output before destroying it
b) only delete *unused* displays (thanks Aaron for clarifying)
so we check if the output has a crtc and if it does we don't
delete it.
v3: drop the option to delete unused displays, just encode
