(Get the code!)
I have the exact same problem, using an Ati HD3650 graphics card on a HP EliteBook. As #740126 seems to be related to Intel only I can't see that this is a duplicate.
In my case, this will happen very randomly and in Ubuntu Classic only, I have so far not experienced the bug in Unity. The screen will freeze, normally as I am working on something (no discernable pattern) and I'm left with a mousepointer which is context-sensitive even though I'm unable to interract with the OS. Shifting to a different display/console (Ctrl-Alt-F#) while using external dual-screens will result in black screens. Changing back I have a graphical glitch covering a square around where the mouse-pointer is at the moment that does not move arount with the mouse-pointer. While on my laptop-screen only I can change to a different terminal and restart gdm, that will usually "fix" the problem and I can start a new session.
I'm using the comercial Catalyst 11.5 drivers, older drivers seemed veeeery slow for some reason, resulting in stuttering and tears..
