EDIT: : The first link mentioned in the question may work for some.

In the latest hp laptops like hp-au111tx(mine), to change the brightness/backlight there are two function buttons which can be used(f2 and f3). The problem is that these two buttons are not working in Ubuntu 16.04 but working in Win10. I have a dual booted laptop. Is there a way to solve this problem.

I followed the following but there was no result:

  • For me, the [first link](https://antonyagnel.com/2016/09/14/how-to-fix-brightness-control-not-working-in-ubuntu-16-04-lts-xenial-xerus/) in your question worked (on an old HP Pavilion g4). – Garrett Apr 16 '18 at 04:45

First open the terminal,

$ xrandr --current # determine the output display, which is eDP-1 for HP x360
$ xrandr --output eDP-1 --brightness 0.75 # --output <primary display>

This works for me.
