Subject: [PATCH] Bug 699757: disable epo device for x11 devices
The epo device interferes with the operation of the x11 devices when those
are integrating with an existing X application (i.e. xv, or other application
that relies on the 'GHOSTVIEW' functionality).
Disable epo by adding an x11 specific fillpage method.
