Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I've installed Ubuntu 14.04 on my (new) ThinkPad Edge330. Everything worked quite well so far.

I've noticed that the screen wasn't that bright and was a bit disappointed of the ThinkPad, but then I realized that the brightness was much better on a parallel windows 7 installation I did later on.

I already used this tip: Max brightness on NetBook

I did increase the brightness to an acceptable level (could be the actual max. brightness, or is there a way to increase it even further?) But now unfortunately I cannot change the screen brightness at all anymore. Not by using the FN keys or in the system settings.

Actually I Just fixed it,

  1. By adding the options suggested in Max brightness on NetBook

  2. Creating a file: /usr/share/X11/xorg.conf.d/20-intel.conf with the content: Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0" EndSection

Now everything works quite well, I can access the maximum brightness, brightness control works and additionally I can switch of the screen completely (This was not possible before)
