I used "sudo apt-get install compiz compizconfig-settings-manager", once there I browsed to "Compiz Config Manager" / clicked on "OpenGL" / and UNCHECK "Sync to VBlank". These steps are what I took on my DELL Inspirion 1525 running Ubuntu 11.04 Natty to resolve the freezing problem I was getting when I would return to my laptop while the screensaver was on. If the problem arises or these steps cease to work I shall update all my info.
