This tool works under Wayland fine. Verified under KDE.

Remove the relevant section from the README.

Maybe it's because I am using i2c-dev and ddcutil.

Doesn't work for me on Wayland. I did a clean install of Ubuntu 22.04.4 LTS. Changing the brightness or any other settings does nothing when on Wayland.
