Hardware

Marchyo enables common hardware support (Bluetooth, Thunderbolt, power management) by default. Some peripheral-specific support is opt-in.

Available options

Option	Default	Description
marchyo.hardware.logitech.enable	false	Logitech wireless device support (Solaar GUI + udev rules)
marchyo.hardware.ddc.enable	true	DDC/CI external-monitor brightness (ddcutil, i2c bus + group), desktop-only

Logitech wireless

Enable support for Logitech Unifying / Bolt receivers and the Solaar management GUI:

{
  marchyo.hardware.logitech.enable = true;
}

This turns on hardware.logitech.wireless with the graphical Solaar tool, so you can pair devices and tune per-device settings.

External-monitor brightness (DDC/CI)

Enabled by default with the desktop. Marchyo loads the i2c-dev module and its udev rules (hardware.i2c), installs ddcutil, and adds Marchyo users to the i2c group so brightness/contrast of external DP/HDMI/VGA displays can be set over the i2c bus. Laptop panels use backlight controls instead. Opt out with:

{
  marchyo.hardware.ddc.enable = false;
}
