I have the exact same problem on my Hp Pavillion dv6000t. This problem started shortly after I upgraded to Gutsy Gibson. Interestingly enough my screen dimmed the moment that I opened Gnome power manager. My power settings are as follows:
Put computer to sleep: Never When laptop lid is closed: Blank Screen When battery power is critically low: Shutdown Put display to sleep when inactive for: 16 min Dim brightness by: 70% Dim display when idle box: checked Note: I am using the restricted NVIDIA driver. Additional information can be supplied if needed. -- Screen dims and brightens randomly https://bugs.launchpad.net/bugs/158343 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
