To make X -configure work properly, the output of fixup_video_driver_list()
should be in order of preference. Otherwise, the config file may use
the incorrect driver for some devices.
In particular, the drivers that work for all (or many) devices need to be
last in the list. Since the modesetting driver works for many devices,
it needs to be considered a fallback driver.

We can only request one fd per device from systemd-logind. If a fd is re-used
by the same device, releasing the fd from one device doesn't mean we can close
it. The systemd code knows when it's really released, so let it close the fd.
Test case: xorg.conf section for an input device with hotplugging enabled.
evdev detects the duplicate and closes the hotplugged device, which closes the
fd. The other instance of evdev thinks the fd is still valid so now you're
playing a double lottery. First, which client(s) will get the evdev fd?
Second, which requests will be picked up by evdev and which ones will be
picked up by the client? You'll never know, but the fun is in finding out.

This patch introduces a new key MatchSeat in xorg.conf (also applies to
any .conf file in xorg.conf.d). It will allow targeting a given
"Device", "Screen", and/or "ServerLayout" section to a particular
seat only (specified by option "-seat" in X server command line),
so that other seats won't be affected.
Without this patch, one needs to write a separate xorg.conf.custom
file and pass it to X server via "-config" option, if one wants that
these settings only apply for the right seat. However, in some cases,
this solution is undesirable or even impossible (e.g. when using GDM,
which doesn't allow X server command line customization).
Example file (/etc/X11/xorg.conf.d/seat1.conf), which would be ignored
by X server unless it was started with "-seat seat1" option:
Section "Device"
Identifier "card0"
Driver "nvidia"
Option "NoLogo" "True"
MatchSeat "seat1"

This patch was first tested in a multiseat setup with multiple

The peculiar way we handle coordinates results in relative coordinates on
absolute devices being added to the last value, then that value is mapped to
the screen (taking the device dimensions into account). From that mapped
value we get the final coordinates, both screen and device coordinates.
To avoid uneven scaling on relative coordinates, they are pre-scaled by
screen ratio:resolution:device ratio factor before being mapped. This
ensures that a circle drawn on the device is a circle on the screen.
Previously, we used the ratio to scale x up. Synaptics already does its own
scaling based on the resolution and that is done by scaling y down by the
ratio. So we can remove the code from the driver and get approximately the
same behaviour here.

This is largely backwards-compatible, hence the input ABI minor bump only.
Drivers we care about either return BadValue on a mode that's not
DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
here is vmmouse, which currently ignores it and would not reset anything.
This should be fixed if the reset is required.

Our in-house parfait 1.1 code analysis tool complained that every exit
path from xf86ValidateModes() in hw/xfree86/common/xf86Mode.c leaks the
storeClockRanges allocation made at line 1501 with XNFalloc.
Investigating, it seems that this code to copy the clock range list to
the clockRanges list in the screen pointer is just plain insane, and
according to git, has been since we first imported it from XFree86.
We start at line 1495 by walking the linked list from scrp->clockRanges
until we find the end. But that was just a diversion, since we've found
the end and immediately forgotten it, and thus at 1499 we know that
storeClockRanges is NULL, but that's not a problem since we're going to
immediately overwrite that value as the first thing in the loop.
So we move on through this loop at 1499, which takes us through the
linked list from the clockRanges variable, and for every entry in
that list allocates a new structure and copies cp to it. If we've
not filled in the screen's clockRanges pointer yet, we set it to
the first storeClockRanges we copied from cp. Otherwise, as best
I can tell, we just drop it into memory and let it leak away, as
parfait warned.
And then we hit the loop action, which if we haven't hit the end of
the cp list, advances cp to the next item in the list, and then just
for the fun of it, also sets storeClockRanges to the ->next pointer it
has just copied from cp as well, even though it's going to overwrite
it as the very first instruction in the loop body.

DGA only handles master devices but it does intercept slave device events as
well (since the event handlers are per event type, not per device).
The DGA code must thus call into UpdateDeviceState to reset the button/key
state on the slave device before it discards the remainder of the event.
Test case:
- Passive GrabModeSync on VCP
- Press button
- Enable DGA after ButtonPress
- AllowEvents(SyncPointer)
- Release button
The button release is handled by DGAProcessPointerEvent but the device state
is never updated, so the slave ends up with the button permanently down.
And since the master's button state is the union of the slave states, the
master has the button permanently down.

For non-PCI video devices, such as those found on many ARM embedded
systems, the X server currently requires the BusID option to specify the
full path to the DRM device's sysfs node in order to properly match it
against the probed platform devices.
In order to allow X to start up properly if either the BusID option was
omitted or no configuration is present at all, the first video device is
used by default.
