Tnxs for the suggestion. I have compared Xorg.0.log vs Xorg.0.log.old.
In both cases the system has detected I have a CRT monitor.
In the good case, the monitor is detected as a "KDS visual-sensation"
model, while in the alternate case it does not recognize the monitor and
thus assumes it is a generic monitor. This latter result limits the res
offered to either VGA or SVGA ONLY.
This is NOT a problem with any distro prior to FC6. If I swap hard
drives to an FC5 (or FC4), the monitor is always detected correctly and
the full set of modes are offered.
