I am using Ubuntu 20.04 on a Dell XPS 15 7590. As you may know, my model has the OLED screen. Screen brightness functionality does not work so when I am using the intel card, I have to enter this in the terminal:
xrandr --output eDP-1 --brightness 0.5
And when I am using my NVIDIA card, I have to enter this:
xrandr --output eDP-1-1 --brightness 0.5
Is there a way I can write a script that will be invoked whenever I press
Fn + F10/F11 to control the brightness? Here is a pseudocode:
if card = intel: xrandr --output eDP-1 --brightness 0.5 else: xrandr --output eDP-1-1 --brightness 0.5
Fn + F10 is suppose to increase the brightness.
Fn + F11 is suppose to decrease the brightness.
