Public bug reported: On imac 2011(12,1) 21,1 inches; using the keyboard brightness keys shows the brightness increasing or decreasing; but the brightness itself does not change in any way; by default brightness will be set to full by ubuntu.
I was only able to change brightness with AMD catalyst or xrandr --output LVDS --brightness 0.9. Ubuntu also does not recognize the imac auto-brightness hardware I guess. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1020373 Title: Brightness control not working on Ubuntu 12.04(mac) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1020373/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
