Hi Alex, you've responded to Felix comment but this is not the original
problem. 

As far as I know, my desktop size is 1920x1200 and doesn't exceed 2048 in
either dimension.  My card only has a 2 physical outputs DVI and S-video.  Only
DVI-0 is connected, so there is no "other monitor" left open that would change
the desktop size.

(II) RADEON(0): Output VGA-0 disconnected
(II) RADEON(0): Output DVI-0 connected
(II) RADEON(0): Output S-video disconnected

Nevertheless...

The only hint that I have so far is the "r300: CS space validation failed."
message. If it's a problem with the desktop compositor violating the contract,
which Gnome component is reponsible? Just trying to log the bug at the right
level.

I'll try using another desktop environment tonight.

Thanks
