I had the following problems (mbp6,2 + ubuntu 11.04): no backlight control no notifier-popup which usually shows that pommed is running/working
Then I noticed that (the standard) nvidia_bl was not loaded. I loaded it with sudo modprobe nvidia_nl. Now the pop-up (on the upper righthand side of the screen) 'worked' again, but no change in brightness. I stopped pommed (sudo service pommed stop) and ran it manually with debug mode which shows that it adjusts the level from 0 to 2047 when hitting F1/F2 (or Fn-F1/Fn-F2 if you have fn-mode set to 2 in /etc/pommed.conf). similar, pommed -f showed it was happy with what it found (no backlight complaints). I reverted to mbp_nvidia_bl as a test and this worked: uninstall the nvidia_bl in 'synaptic package manager'. go to the repository in the 'settings' menu there and add the old maverick repository for mactel: click on add in the 'other software' tab and fill in 'deb http://ppa.launchpad.net/mactel-support/ppa/ubuntu maverick main' back in the main window of the synaptic package manager you 'reload' and install the mbp_nvidia_bl After a reboot, you first have to check whether mbp_nvidia_bl is loaded. (otherwise do 'sudo modprobe mbp_nvidia_bl') My /etc/X11/xorg.conf does not contain the extra option (commented out): #Option "RegistryDwords" "EnableBrightnessControl=1" I don't have a '_bl' anymore in the blacklists: 'grep bl /etc/modprobe.d/*' gives nothing.
