After yesterday routine update I noticed that my trackpoint buttons stopped working. That's annoying, because those buttons are the main buttons I use on my laptop at all.

Also I noticed that my brightness became somewhat broken, since then it always defaults to max brightness after restart.
I would appreciate any clues on how to make all three trackpoint buttons work again.
