Weird brightness issue after UP7

Postby dclement on Sun Dec 01, 2013 10:52 am


This week we've updated my wife's laptop to UP7 (mate). The update went fine, but we have a strange issue with screen brightness.

We decrease the brightness of the LCD with fn+up/down buttons, but after a few minutes, it resets itself to the max. I've read that it happens to other users at startup/restart, but here it's in the middle of a session, even without doing anything (we've checked...)

Could it be that the brightness management has changed with UP7 and we should install or update or remove some packages?

TIA for any suggestion - best regards, Daniel
