Well, thanks to a very informative post on the ubuntu forums: http://ubuntuforums.org/showthread.php?t=1152121&highlight=fglrx , my problem is now fixed.
To do a bit of copy/pasting from that post: Edit /etc/ati/amdpcsdb In the section labeled [AMDPCSROOT/SYSTEM/DDX] Add this: EnableRandR12=Sfalse and in xorg.conf add this: Option "EnableRandR12" "false" I believe I rebooted at this point. I then set up pairmodes using the aticonfig command: sudo aticonfig --add-pairmode=1152x864+1440x900 then it was a matter of loading up Catalyst Control Center, and activating Big Desktop, and then setting the overall screen resolution to 2592x900. Presto! Completely working and fast compiz. I hope this fixes your problem, Graham.
