Same problem here, running up to date Hardy Beta. This has been working on Gutsy and earlier Hardy Alphas for me, but not now.
It appears my laptop goes into a "chronical state of dimmed" since when I plug in or out the AC it still remains at dimmed brightness (although the AC dim-state is slightly brighter). If I turn the brightness up manually (OEM function keys) then it will remain there temporarily, but as soon as I (un)plug the AC it goes back to this dimmed state. If I follow the suggestion in bug description above I get the right "undimmed" brightness, BUT, the screen then refuses to dim down from that. I'm suspecting that it still thinks it's dimmed, and that I've just upped the dimmed brightness by doing that. -- Dim on idle does not brighten with activity https://bugs.launchpad.net/bugs/199522 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
