A new --with-fallback-input-driver=foo option allows selecting a
fallback driver for the server if the driver configured for the device
is not found. Note that this only applies when the device has a driver
assigned and that module fails to load, devices without a driver are
ignored as usual.
This avoids the situation where a configuration assigns e.g. the
synaptics driver but that driver is not available on the system,
resulting in a dead device. A fallback driver can at least provides some
functionality.
This becomes more important as we move towards making other driver true
leaf nodes that can be installed/uninstalled as requested. Specifically,
wacom and synaptics, a config that assigns either driver should be
viable even when the driver itself is not (yet) installed on the system.
It is up to the distributions to make sure that the fallback driver is
always installed. The fallback driver can be disabled with
--without-fallback-input-driver and is disabled by default on non-Linux
systems because we don't have generic drivers on those platforms.
Default driver on Linux is libinput, evdev is the only other serious
candidate here.

This patch introduces a new flag ATTR_KEY for hotplugged input devices,
so we can better distinguish between real keyboards (i.e. devices with
udev property ID_INPUT_KEYBOARD="1") and other key input devices like
lid switches, power buttons, etc.
All supported hotplug backends (udev, hal, and wscons) will set both
flags ATTR_KEY and ATTR_KEYBOARD for real keyboards, but udev backend
will set ATTR_KEY, but not ATTR_KEYBOARD, for non-keyboard key input
devices (hal and wscons will set both flags in any case). With this
distinction, kdrive input hotplugging mechanism will be allowed to only
grab real keyboards, as other key input devices are currently not
supported.
In order to don't break current behaviour, this patch will replace all
ATTR_KEYBOARD occurrences with ATTR_KEY in hw/xfree86/common/xf86Xinput.c.

216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

InputClass sections use various MatchFoo directives to decide which device to
apply to. This usually works fine for specific snippets but has drawbacks for
snippets that apply more generally to a multitude of devices.
This patch adds a NoMatchFoo directive to negate a match, thus allowing
snippets that only apply if a given condition is not set. Specifically, this
allows for more flexible fallback driver matching, it is now possible to use a
snippet that says "assign driver foo, but only if driver bar wasn't already
assigned to it". For example:
Section "InputClass"
Identifier "libinput for tablets"
MatchIsTablet "true"
NoMatchDriver "wacom"
Driver "libinput"
EndSection
The above only assigns libinput to tablet devices if wacom isn't already
assigned to this device, making it possible to select a specific driver by
installing/uninstalling it.
