Here are all the config settings I have in /etc/X11/xorg.conf.d (there
is no main xorg.conf file):
$ cat 10-evdev.conf
#
# Catch-all evdev loader for udev-based systems
# We don't simply match on any device since that also adds accelerometers
# and other devices that we don't really want to use. The list below
# matches everything but joysticks.
