Bug Description
I cannot modify the brightness level through Fn + F[89] keys even if I can control it through `/sys/class/
I followed the instructions on https:/
I've already tried `xev`, `udevadm monitor`, looking in dmesg and /var/log/kern.log, using /lib/udev/keymap for monitoring keyboard input.
Per suggestion by apw in #ubuntu-kernel, I installed input-utils and ran `sudo lsinput` to get a list of devices. On each device, I did `sudo input-events -t 10 $number` to watch for events. Each time I pressed a regular key ("c"), another Fn key (Fn + F6 / Volume Up) and Fn + F[89] (brightness up/down). I didn't get any output for the Fn + F[89] events.
