laptop system : gnome-control-center brightness bar differs from unity shortcut activated brightness bar

[Sasa Paporovic]

On Laptop system there are two ways to change monitor brightness.

The first is with the gnome control center -> adjusting the brightness bar.

The second way is to use keybord shortcuts for the monitor brightness. -> In this case unity shows a wiget on the desktop with a bar for brightness.

Unfortunally the bar status of both ways are not synchronized.

For illustrating please look at the attached screenshot.

Steps to reproduce:

1. Install Raring on a laptop system
2.Use the system center option to adjust the monitor brightness.
3.Use (if available) keybord shortcuts to adjust the monitor brightness.
4.See that both brighness bar differ.

Additional:

On the system I use brightness is not really adjustable(kernelbug), but anyway the both bars should not differ in anyway.
