I am not able to set my screen brightness on my macbook running arch linux. The macbook is a 15 inch 2012 model and I am using Arch Linux 4.11.5-1. I have read up on arch linux wiki "backlight", "Mac", and different other forums and posts but I cant quite get it to work.


What is your Desktop environment? In the past I had many problems regarding screen brightness on LXDE desktop environment and changing to XFCE fixed all my problems.

  • I am using Openbox – user236618 Jun 18 '17 at 18:46
  • Overall the LXDE desktop environment is itself built around Openbox. I would try a more modern DE. Try for example XFCE, MATE or GNOME and see will it work. – Dankata Jun 18 '17 at 18:52

If anyone stumbles upon this issue in the future, here is how I solved it. I just used gmux_backlight +50000 and it worked perfectly.
