W520 ubuntu tip learn

So today was the first day I used my laptop without external screen on ubuntu 12.04 .

Screen brigthness was way too bright and realized I couldn't adijust it with tthe Fn keys.

So here's my tip of the week.

To enable Fn key brightness on your ubuntu 12.04 lenovo laptop add the following line in the Device section of your /etc/X11/xorg.conf



 Option         "RegistryDwords" "EnableBrightnessControl=1"


Hope it fixes your problem !
