Xbacklight isn't working - i3 edition

Also when I was using the xfce version I could run xbacklight with no problems, but now that I installed the i3 version it won’t do anything. Any ideas why it might be so and how to fix it?

Do you have xorg-xbacklight package installed?
Are you using Intel drivers?
Do you see any output when you are trying to execute xbacklight?
Does it work as root (with sudo)?

  • Yes I have it installed
  • Nvidia and Intel ( I have a laptop )
  • No I don’t see any output
  • Nope

I eventually found out an alternative to xbacklight that works for me. It’s called brightnessctl
You use it like this:
brightnessctl s 10%- to decrease the brightness
brightnessctl s 10%+ to increase the brightness

acpilight is another nice package. It’s xbacklight replacement, but based on acpi and working with other than Intel drivers. It can be used with the same options as xbacklight :slight_smile:
