I confirm Victor's comments. I tried with a blank screensaver and the problem remains. If I disable the screensaver, the system remains stable much longer (there seem to be _other_ problems with X).
So bottom line: recreate 1: -------------- - configure a screen saver (blank) - let the computer idle for a few hours - when returning from the screensaver, Xorg sits at 100% CPU and yields a moving cursor over empty background. No windows, no menu etc. Keyboard not responsive either (no ctl-alt-backspace, no ctl-alt-F1...) - killing X takes you to "recreate 2" recreate 2: -------------- - log in under GDM (enter a gnome session) - log out - log in again => X starts spinning at 100% and yields a moving cursor over empty background. No windows, no menu etc. Keyboard not responsive either (no ctl-alt-backspace, no ctl-alt-F1...) In either case, the only option is to reboot the computer. I have the _impression_ that using a GL screensaver (such as hypetorus) accelerates the recreate 1 procedure. In this scenario, hypertorus would sit at 100% CPU. Killing it would yield an Xorg at 100% CPU, and then continue from step 3 of recreate 1. ** Summary changed: - X hangs and not recoverable after screen power save mode on Dell Hybrid Studio + X hangs and not recoverable after screen saving or logout/login with intel 965gm -- X hangs and not recoverable after screen saving or logout/login with intel 965gm https://bugs.launchpad.net/bugs/282081 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
