Bug#836939: gnome-settings-daemon: Screen brightness defaults to a very low value and can't be changed with Function Keys, Applet or in System Settings

[Tilo Villwock]

The mutter update came in today and I can confirm, that everything is
working as expected again. So I guess we can close this bug?

The only thing that's kind of odd is that the overlay for brightness
does this small but noticable wiggling motion on the horizontal axis
now. But that's rather cosmetic and I don't mind it as long as the
brightness controls work again.
