that's actually GNOME doing it, it detects the device type and hides the
pointer when an event comes from that device. Not sure what other desktop
environments do, maybe the same thing? Either way, it's not something that X
controls, so if the device is labelled as TOUCHSCREEN that should be enough
from our side.
