It started happening when I switched to Gnome. At first I had both Gnome and
Unity next to each other and when I logged in to Unity, I could still change
the backlight normally.
It only doesn't work under Gnome strangely.
I've tested the new kernel, but it had no effect:
Linux
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.8
