Comment 8 for bug 59841

Also see bug 3731, which is capturing the general bug of ubuntu's bad monitor detection system in general.

It seems that the root cause is that xresprobe is not able to detect a variety of monitors, so we're looking at fixing and/or replacing it.

Starting with feisty, xorg's built in monitor detection system is reputed to be pretty good, so one thing to try is to move xorg.conf to xorg.conf.orig and restart X, as described above.
