[screen] Brightness slider in gnome-control-center is not updated when brightness is changed by hotkey
Last modified: 2012-06-12 13:04:53 UTC
For systems that have hotkeys to adjust screen brightness, the brightness slider in "gnome-control-center screen" is not responding to brightness hotkey actions. To be clear, brightness hotkeys are working fine and they can be used to change screen brightness. The problem is the UI in gnome-control-center is not reflecting the change of screen brightness.
