Hi there, I seemed to have had the same problem. I tried the two solutions provided before, but they did not work. I notice from your xorg.conf that you are using fglrx, so am I. I think that changing the following lines
Option "VideoOverlay" "off" Option "OpenGLOverlay" "on" to Option "VideoOverlay" "on" Option "OpenGLOverlay" "off" ...then saving and then reloading the X server may fix the problem, it did for me. Hope this works for you. -- Lock Screen not working anymore https://launchpad.net/bugs/68123 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
