FWIW: Sean Fenton's advice about disabling sync_to_vblank in gconf- editor seems to have done the trick: I just left my laptop on overnight with Transmission running (which was a recipe to activate the bug) and it came back no problem.
The key location is: /apps/compiz-1/plugins/opengl/screen0/options/sync_to_vblank (since there are a couple of keys with the same name). I still fervently hope that this bug gets fixed soon, however. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/762918 Title: Natty Screensaver freezes system after some period of inactivity -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
