You can query for the display name sing

xrandr --listmonitors | awk '$1 == "0:" {print $4}'

On a new XPS 15 7590:

When I run the command xrandr --listmonitors | awk '$1 == "0:" {print $4}'

I get the result

eDP-1-1

Changing this in the commands on the README worked, and this command does reduce the brightness

xrandr --output eDP-1-1 --brightness 0.6

However, the brightness buttons do not change the brightness. The path to the device is still card0eDP-1, but the dell-brightness.sh file does not work for me.

Did you create /etc/acpi/events/dell-brightness-up and /etc/acpi/events/dell-brightness-down to handle the key events as described in README?

KenEucker commented 4 years ago

@lrkwz Yes I did. I followed every step in the README.

sorry, maybe @TillmannBerg can be of more help.
