On Fri 5 April 2013, the brightness keys _almost_ work -- if the "Brightness" slider in the System Settings | Brightness & Lock is moved to roughly 2/3 of the brightness, the keyboard brightness keys can control _some_ of the brightness. It is still not as granular as 12.04 LTS or 12.10, and full brightness and full dimness are impossible, but I finally have some amount of keyboard control over brightness again.
Did I make a mistake when I assigned this bug to gnome-control-center? I'm a bit surprised that no one has asked for logs or edid info or anything else about my system to try to debug this regression.

I upgraded to Raring on Mar 17, and the brightness keys no longer work. The indicator appears but the slider does not slide and the screen brightness does not change. The brightness slider on the brightness and lock control panel feels like it has lost granularity -- but I cannot recall the exact behavior of the older slider.
