i have also this issue in 10.04. additionally if i disable screensaver and disable shutting down monitor if idle for some time i still get a black screen after some minutes of idleing. it seems some more powersaving options are totally ignored.
anyhow, i will try later some of this mentioned tests and workarrounds to see if how they influence the behaviour. -- Disabling the suspend and hibernate locks via gconf-editor doesn't do anything (from Intrepid to Karmic included) https://bugs.launchpad.net/bugs/255228 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
