Same for me, I can confirm that the brightness keys have no effect. If started on battery then the screens stays dark on press of keys, and does not change when plugged into mains later in the session. If started on mains then it stays bright, even if keys are pressed or the mains is disconnected.
The Desktop Notification is occurring, showing what the brightness level 'should' be, but the actual brightness never changes. I will add logs shortly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/808729 Title: Screen Brightness will not work on Samsung NF210 Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/808729/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
