Screenwatch is a small utility to send drm change events over the system DBus and a daemon to receive the and run xrandr.

There is a udev rules file, a DBus policy file, a script to install everything in the proper place, and an XDG autostart file.

screenwatch-event just calls the proper method.

screenwatchd establishes a connection to the system bus, and waits for Change() calls. On change, it looks at all the displays it's configured for (via -p) and makes xrandr calls depending on the status read out of /sys/class/drm.

It is intended to be run as a normal user.
