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.
