I've done quite a bit of searching on this problem (forums / search engines) and have not had any luck finding a solution. I have a Dell Inspiron 11z laptop with a fresh install of Kubuntu 10.10 and I'm not able to adjust the backlight brightness using the function keys. (If I go into Power Management | Edit Profiles | Performance... I can adjust it there only). If I press brightness dn or brightness up the indicator shows up but doesn't change one way or the other. Any suggestions?
