I have seen a lot of users with this problem on 11.04 Natty, I too have been having this problem since day one on my DELL Inspirion 1525. I have seen a couple threads that insit on installing "xscreensaver", it worked for a few days then my computer locked up on my last night twice. I will give the "Compiz" workaround a shot this afternoon.
