UPDATE: Read submitter's latest post first.

After the upgrade, the computer crashed at the login screen where it
froze. I could not switch to a VT, login via SSH, or safer reboot via
the magic keys: RESIUB.

Anyway - after a hard reboot, I noticed the graphics setup had changed.
It was obvious because of the way the 22" handles resolutions or signals
it doesn't like. It's cloning the only resolution it has made available:
1280x1024.

At some point after upgrade to 14.04 and before my second attempt to run
Xorg, the original xorg.conf file was renamed (and not replaced) with
the date added on the end. I replaced it with the original xorg and
eventually tired different things to fix it by commenting certain lines.

The second run of Xorg: The graphic output looked the same with cloned
1280x1024. I noticed that even though I restored my xorg.conf file, it
proceeded to unload radeon driver and then load and use FBDEV with LLVM
pipe. Yay? Nope, I use folding@home so the CPU cores are too busy for
OpenGL. Having and not having xorg.conf present seems to not have an
effect on the resutlts. :(

The output of xrandr is:

<QUOTE>
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 1024, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024      77.0*
</QUOTE>

I see no obvious reason from the log files why radeon was unloaded and
not used for this card which is on the supported list still. Any ideas?

Thanks much.
