After running for a few minutes (amount of time varies, sometimes 5 minutes after login, sometimes an hour), X freezes and becomes unresponsive. Often the mouse pointer still responds to movement but cannot select anything. It is possible to SSH in from a remote machine and see that Xorg is using 100% CPU. I am not a coder but I will give you all the help I can in resolving this, because this machine is currently unusable. I submitted this bug originally to Ubuntu's lanchpad, and all of the relevant hardware information is attached there: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/450669
