I also have the problem with constant dimming. When I switched of all the dimming settings in gconf-editor under apps > gnome-power-manager > backlight (there are some settings that are only available here, and not from the settings applet) this no longer happens. It still happens after resume from suspend, but I can live with it.
I suspect it's related to this other bug, but I haven't been able to confirm it: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/392122 -- hotkeys adjust brightness non-monotonically on EEEPC 1005PE https://bugs.launchpad.net/bugs/512567 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
