"your display server is broken"?


I was using my laptop when suddenly the screen faded out, then returned with an error message:


that translates to:

“Session active, not inhibited, screen idle. If you can see this text, your display server is broken and you should notify your distributor. Please see gnome-power-manager and blanking (removal of bodges) « Technical Blog of Richard Hughes for more information.”

This happens randomly. Any suggestions? I’m using openSUSE 11.2 x86-64, fully updated, my laptop is an Acer 7720 with Intel X3100 video.
