Tested with last upstream kernel `linux-image-4.0.0-040000rc5-generic` the problem persist.
Yes, the issue started to happen after an update/upgrade, I'm not sure when exactly started. Anyway if you check bug #122959, @rpgmaker says "Going over all the versions between 12.10 and 14.04 revealed that 13.04 is the only one where the brightness keys still work. " [0] Where can I download a very old kernel package ( 13.04 time ) ? or better a 13.04 iso ? ( so I can test it ) [0] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1229591/comments/60 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1435039 Title: [Dell Inspiron 14z (N411z)] brightness FN keys don't generate evdev events To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1435039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
