Description of problem:
After installing F11 from the DVD, the display properties show only the 800x600 and 640x480 options.
Will attach dmesg and Xorg.0.log. Will also test with nomodeset and report.

I don't have a /etc/X11/xorg.conf

With nomodeset=1 the display only goes to 1024x768. Still not what the monitor is capable of doing

What display is this? It looks like we're not getting EDID from it at all.
I attached another monitor, an old 15" CRT (also samsung). That too could only do 800x600.
(also: all the F11 installs I've tried are 64-bit. I've not yet tried a 32-bit install; though it doesn't sound like a problem with the bitness.)
Is there any hope for this to work on this monitor at all?
In other words, can the EDID requirement be worked around and a custom resolution be specified? (I tried making a minimal xorg.conf but that didn't work.)
Actually I could get 1280x1024 by using an xorg.conf and getting the modeline from 'cvt' output. Works with kms enabled as well as disabled.

This is a hardware bug: monitor doesn't expose EDID information.
