I have a related problem, possibly not the same. I am running Xubuntu 11.10 64 bit, patched only to normal distribution level, on a dell d620 laptop.
There is no gnome-settings application, the nearest I can find is settings->settings-manager-> and then various panels have settings related to blanking. it isn't very clear which should be used but any screen-blanking I've set to 'none' have so far had no effect - the screen still dims after a few minutes. I have installed dconf-editor as suggested elsewhere and used that to disable screen dimming, but it still dims. After the screen has dimmed, pressing a key does not bring it back. However, the keyboard brightness changes (fn-cursor-up etc) DO work and must be used to bring the screen back to a usable brightness. The backlight is not switched off - it's just that it dims, and the normal level is not restored on a keypress. Logging out does not fix this. In fact, it makes it worse : the screen brightness can be adjusted at the login menu but it jumps up and down with successive changes as described by another poster. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/872652 Title: screensaver backlight stuck off, system looks hung To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/872652/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
