Having a similar problem, on Acer 8204. Screen is very dim and plugging/unplugging makes no difference.
As a workaround, disabled all dimming and set /proc/acpi/acer/brightness (was 0) seems to do the trick manually. ** Attachment added: "logs" http://launchpadlibrarian.net/12908466/logs -- Screen does not dim when on battery, Acer Aspire 5601AWLMi Laptop https://bugs.launchpad.net/bugs/67322 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
