Public bug reported: 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: gnome-control-center (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1156477 Title: lenovo thinkpad t530 brightness keys regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1156477/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
