My machine freezes after an extended period of inactivity.

I recently upgraded from Ubuntu 10.10 to 11.04. This is when the problem started. When I try to access my sleeping machine, I can see the mouse moving on the screen (because I'm moving it) but I can't get the screen saver to go away. The only way I have been able access it after it's been idle is to power off and back on by holding down the power button.

I have posted my CPU info below. If someone could help me out I would really appreciate it.

If you read the comments it works for some people on 11.04
