since I installed XUbuntu 12.04 on my notebook, brightness controls are no longer working (they used to work before with Smartdimmer). I tried several suggestions, starting from gnome-settings with gsd-backlight-helper to the Xorg.conf file, but both didn't help, maybe someone can give me further advice?
