I had the same problem, but then I noticed that it's a UI inconsistency problem. The slider under AC power tab has the opposite meaning of the slider under Battery tab. Maybe it's just this, maybe it's something else.
Here is the bug report for this (and also a link to a forum discussion with the same problem): https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/155840 -- Screen brightness goes down automatic https://bugs.launchpad.net/bugs/199466 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
