Keyboard backlight with Tuxedo Infinitybook Pro 16

I currently struggle to get the keyboard backlight working with my Tuxedo Infinitybook Pro 16. I have the following config

  hardware.tuxedo-keyboard.enable = true;

I thought that should be enough but maybe I miss something?

Do you have the “control center” installed?

I did but did not work. Now I am using tuxedo-rs as the repo from blitz is archived and no more maintained

Consider using tuxedo-rs as a replacement. It has less features, but should get the job done well enough. Alternatively, please feel free to fork this repo.
