Okay, very strange: Approx. 5 minutes after pressing the brightness-up button, the brightness status icon showed up at that spot of the screen (still not showing any status at all) and disappears after a second, leaving the screen proper again.
Btw.: The version of gnome-power-manager is 2.21.1-0ubuntu1.
