Currently I am using following to control external monitor brightness

xrandr --output HDMI-1-2 --brightness 0.65

which is handles brightness from software not from hardware.

Problem with xrandr

  • Does not persist the changes
  • Changes get reverted after some time
  • Just software level brightness control
  • Not supported in Wayland

Is there any better way to control external monitor/s brightness in Fedora while mitigating these issues?

You can try ddcutil to control the monitor directly, have a look at this guide and install instructions.
