Ubuntu 11.04 Black screen after screensaver
Ubuntu 10.10 upgraded to 11.04 on a Lenovo G560 with Intel GMA [1]
I am running with the unity-desktop (Ubuntu selected on login).
Sometimes after the screensaver (-15 [2]) have been active, the screen is black, except the mouse is visible.
I have not been able to disable the screensaver just typing the password. If I kill the screensaver from a TTY terminal, then I can control the musicplayer (suppose other things also works), but still black screen with mouse.
If I kill compiz (-9 [2]) from a TTY terminal then I can see my background image, and after a short time the normal top/left launcher are shown.
I have seen the problem after the screensaver have started automically and been active for some time then I have seen the problem some times. Only the last time I found out how to do.
