The same thing happens to me too, display freezes put mouse movement is registered (the mouse moves on the screen).
I have Ubuntu 11.04, screensaver set to GLSlideShow only the same thing happens with gnome-screensaver. I think it might have something to do with Lock screen, will test and post again.
