This workaround (with "EnableBrightnessControl=1") does not work anymore with nVidia driver 270.41.06 (in 11.04).
I heard about a possible solution: just add "acpi_osi=Linux" to kernel options (in GRUB config or manually on boot). So far I have not tested it. I can check it out after a few hours (and report the results). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/726692 Title: Screen backlight adjustment stopped working on MacBook Pro 5,4 and other hardware -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
