ddcutil-service is D-Bus service wrapper for libddcutil which implements the VESA DDC Monitor Control Command Set. In general, most things that can be controlled using a monitor's on-screen display can be controlled by this service.

vdu_controls is a virtual control panel for externally connected VDU's (visual display units). Controls are included for backlight brightness, and contrast. vdu_controls uses the ddcutil command line utility to interact with external displays via VESA Display Data Channel (DDC) Virtual Control Panel (VCP) standards.

This version includes the option to use ddcutil-service, a D-Bus service I've written for smoother/faster access to libddcutil.

To use the D-Bus option, you will also need to install ddcutil-service, which I've also packaged, see:
