What?  If you run tvheadend and kodi on one device you want to wait to start kodi until hdmi is conected, Why? kodi has bugs that cause issues when started before connected to hdmi Sometimes it crashes Sometimes it stops to render text in menu How to work arround?

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.

Shutdown and timed startup automation saves your setup from running 24/7. Configure Kodi         setwakeup.sh #!/bin/sh #$1 is the first argument to the script. It is the time in seconds since 1970 #this is defined in mythtv-setup with the time_t argument #this clears your alarm. echo  0 > /sys/class/rtc/rtc0/wakealarm       #this writes your alarm echo   $1  > /sys/class/rtc/rtc0/wakealarm      set script to be executable sudo chmod   +x /usr/bin/setwakeup.sh Reference https://forum.kodi.tv/showthread.php?tid=155128
