The brightness controls on my Lenovo ThinkPad W510 were not working at first. The display was stuck on a really bright setting which was tough on the eyes. I asked a user on UbuntuForums to help.

He showed me what to do, and recommended the ThinkWiki page for the W510.

Here is the fix:

sudo gedit /etc/X11/xorg.conf

Then add the following line at the bottom of the “device” section.

Option “RegistryDwords” “EnableBrightnessControl=1”
