Kodi keeps crashing when it is started without connected displays. Sometimes I want to startup my kodi setup for some other reasen and start using kodi later.... then kodi was already closed with some crash log file... :(

This script works arround by waiting to start kodi until some hdmi port is connected (modify the grep query to adapt to some other port name).

#!/bin/bash

# Some programs have issues when run without connected display. E.g. Kodi likes to crash when started without any display connected on my system.

# This script starts after some hdmi port is connected.

# Depends on xrandr.
