  10
  11           To configure the driver, pass the options to the {option}`boot.kernelParams` configuration.
  12           There are several parameters you can change. It's best to check at the source code description which options are supported.
  13           You can find all the supported parameters at: <https://github.com/tuxedocomputers/tuxedo-keyboard#kernelparam>

  15           In order to use the `custom` lighting with the maximumg brightness and a color of `0xff0a0a` one would put pass {option}`boot.kernelParams` like this:
  16
  17           ```
  18           boot.kernelParams = [
  19            "tuxedo_keyboard.mode=0"
  20            "tuxedo_keyboard.brightness=255"
  21            "tuxedo_keyboard.color_left=0xff0a0a"
  22           ];
  23           ```
  24       '';
  25     };
  26
  27     config = lib.mkIf cfg.enable
  28     {
  29       boot.kernelModules = ["tuxedo_keyboard"];
  30       boot.extraModulePackages = [ tuxedo-keyboard ];
  31     };
