If the device is present but disabled, the server will still call into SetProperty. We don't have a libinput device to back it up in this case, causing a null-pointer dereference. This is a bug specific to this driver that cannot easily be fixed. All other drivers can handle property changes even if no device is present, here we rely on libinput to make the final call. But without a device path/fd we don't have a libinput reference. The protocol doesn't mention this case, so let's pick BadMatch as the least wrong error code. And put a warning in the log, this needs a workaround in the client. Also, if we get here and the device is on, then that's definitely a bug, warn about that. https://bugs.freedesktop.org/show_bug.cgi?id=89296 Signed-off-by: Olivier Fourdan <ofourdan@redhat.com> Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
xf86-input-libinput - a libinput-based X driver
The official repository for this driver is http://cgit.freedesktop.org/xorg/driver/xf86-input-libinput/
This is an X driver based on libinput. It is a thin wrapper around libinput, so while it does provide all features that libinput supports it does little beyond.
WARNING: misconfiguration of an X input driver may leave you without usable input devices in your X session. Use with caution.
Prerequisites
To build, you'll need the X.Org X server SDK (check your distribution for a xorg-x11-server-devel package or similar) and libinput (check your distribution for libinput-devel or similar).
To get libinput from source, see: http://www.freedesktop.org/wiki/Software/libinput/
To build the X server from source: http://www.x.org/wiki/Building_the_X_Window_System/
Building
To build this driver:
autoreconf -vif
./configure --prefix=$HOME/build
make && make install
Note that this assumes the same prefix as used in "Building the X Window System" above, adjust as required. If you want a system install, use a prefix of /usr.
Install the default configuration file:
cp conf/99-libinput.conf /etc/X11/xorg.conf.d/
This will assign this driver to all devices. Use with caution.
