I have a DELL XPS L702X laptop with the nVidia GTX 555M 3GB RAM with the 120Hz 3D Screen.

I use Ubuntu 12.10 32-bit with the Experimental NVIDIA binary Xorg driver from nvidia-experimental-310(proprietary).

Thanks to all the comments, I got my Fn+F4/F5 brightness working aswell.

Though I did not have an /etc/X11/xorg.conf file to put the settings in, I created it manually using

sudo gedit /etc/X11/xorg.conf

and added only this:

Section "Screen"
 Identifier "Default Screen"
 Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

and saved the file.

I rebooted the system, and now the keys work.

I hope the issue gets resolved at some point.

Thanks again from a new Ubuntu user.
