Public bug reported: Since I have upgraded to 15.04 a couple of days ago, the screen brightness automatically dims after a few seconds that I don't touch the keyboard or touchpad, when running on battery.
This didn't use to happen before the upgrades on 14.04. So I've checked the settings and found this: "Dim screen to save power" which was turned on (if it's a new setting, that makes sense; if this setting already existed, then there's a bug in dist-upgrade if it gets changed). I DISABLED the setting, but the screen keeps dimming from time to time.
