I installed Ubuntu 12.04 on my macbookPro 5,4 and it seems like everything is working well expect the brightness control.

The functions keys are working and when pressing it I see the brightness bar changing, but the brightness doesn't change.

Changing the brightness from the settings tools doesn't work as well.

Any idea?

after reading here , I just edited:

sudo gedit /etc/X11/xorg.conf

and added the line:

Option "RegistryDwords" "EnableBrightnessControl=1".

that's it!
