An update on this bug... I have two raring installs. For one of them the brightness controls work, one doesn't.
The one that doesn't work is a vanilla upgrade to Raring 13.04 from Quantal 12.10. The one that works is also an upgrade from 12.10, but there are two major differences: 1. I installed Gnome Shell 2. I am running the Mir PPA I have no idea which of the above might account for the brightness controls working, but installing Gnome shell should be harmless and it's not a bad desktop - so I'd recommend to try that. I don't recommend using the Mir PPA. There is a question on Askubuntu that I provided the brightness settings you can use (manually) to work around the issue: http://askubuntu.com/a/289177/14916 (specific to a Dell Inspiron N4010) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1105604 Title: Brightness control stopped working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1105604/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
