thinkpad

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.

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after.
