This problem has been plaguing me since the official release of 11.04
I'm starting to get fed up with it!!
I have tried:
Update install of 11.04
Clean install of 11.04
CCSM: disable sync to vblank
Updating fglxr to manufacturer update
Compiz fusion: set metacity as window manager
Purging fglxr entirely
disabling screensaver ( results in system freeze after 15-20 min)
Here is a detailed list of my system. Sorry if it's too verbose, but maybe it
will be helpful.
