Bug Description
The keyboard buttons are working as I get the on screen notification. But it has no effect on the backlight itself.
I rebooted and switched back to 3.19.0-11-generic which works fine, rebooted and went back to 3.19.0-12-generic and it stopped working again, so very confident something broke in the new kernel version.
