Hi 1. When using 16.10, were you able to adjust the brightness via keyboard key press, or you could only adjust the brightness via xrandr?
I could only adjust it with the terminal and xrandr 2. In order to allow additional upstream mainline kernel developers to examine the issue, at your earliest convenience, could you please test the latest mainline kernel available from http://kernel.ubuntu.com/ ~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: after testing the kernel the bug still exists. Not quite clear where to add the flag though. kernel-bug-exists-upstream-v4.17-rc6 the grub issue I had is fixed.
