I have problem with my new netbook. I installed Ubuntu 12.10 and I can't use my brightness key's (Fn+F5/F6). When i use them OSD appears and indicates the increase or decrease of brightness but nothing really happens to screen. I used this command from terminal(and it worked):
sudo setpci -s 00:02.0 F4.B=xx
But I want use my Fn keys. Is it possible to do this?
Thanks for help!

Reboot your system and see if Fn (for brightness) works.
