Bug Description
In 12.04 LTS and 12.10, the fn+f8 and fn+f9 keys properly adjusted my Thinkpad T530's display brightness perfectly.
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.
affects: | ubuntu → gnome-settings-daemon (Ubuntu) |
