I actually think your script isn't what we need .

Code:

#!/bin/bash

OUTPUT=`xrandr -display :0 -q | sed '/ connected/!d;s/ .*//;q'`
xrandr -display :0 --output $OUTPUT --set "Broadcast RGB" "Full"

while true; do
    /usr/bin/kodi --standalone
    #break while-loop if exit was clean, otherwise restart kodi
    if [ $? -eq 0 ]; then
      break
    fi
done

#give exit code to systemd
exit $?

I assume systemd needs the exit-code?

Won't hurt. It was more of a manual hack - that way you can exit kodi - use openbox and when it would crash it would get restarted by openbox.

FWIW: I tested it. Works fine so far.
