spotify kodi startup script
#!/bin/bash
# spotify-kodi startup script
#
# Start spotify, wait for display, start kodi, bring kodi window into focus (again)
#
# # USAGE
# 1. Install somewhere (e.g. /snap/bin/)
# 2. Run as startup item on Linux
#
# # ABOUT
#
# This script solves two problems I had when automatically starting spotify and kodi on my HTPC Intel NUC:
# 1. spotify steals focus from kodi
# 2. kodi gives a black screen when started before TV is on
#
# # spotify stealing focus
#
# Linux spotify cannot start minimized. To fix this, I start both spotify and kodi, and after a while,
# I run wmctrl to give kodi focus back.
#
# # Kodi shows black screen
#
# On my Intel NUC connected via HDMI to my Onkyo receiver connected via HDMI to my Samsung TV,
# if Kodi starts when the TV is not on yet, it 'hangs' in a black screen from which it will
# not recover, requiring a restart of Kodi. Other programs (E.g. desktop, spotify) don't have
# this issue. I've also not found any Kodi setting that fixes this.
#
# The following did NOT work:
# - Blank other displays off (not working)
# - Force video out to HDMI-1 instead of ‘default’ (does not work)
# - Boot into kodi directly as window manager (does not work
#
# As a work-around, I use xrandr to check the display settings, where I have unique output for
# HDMI-1 for three different possible states:
# 1. Receiver off, TV off (or on): HDMI-1 disconnected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
# 2. Receiver on, TV off: HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 708mm x 398mm
# 3. Receiver on, TV on: HDMI-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 160mm x 90mm
#
# The script below runs xrandr until it sees the tv is on, and then starts kodi as usual.
# Start spotify
echo "spotify"
/snap/bin/spotify 1> /dev/null 2>&1 &
sleep 3
# Stat kodi second, but only when TV and receiver are on, using xrandr --query. Sleep until TV and Receiver are on
waittime=0
echo "waiting loop"
while [[ -z $(xrandr --query | grep HDMI-1 | grep "160mm x 90mm") ]]; do
echo "xrandr:" $(xrandr --query | grep HDMI-1 | grep "160mm x 90mm")
sleep 1
waittime=$(($time + 1))
done
# TV and receiver are on here, start Kodi
echo "Kodi"
/usr/bin/kodi 1> /dev/null 2>&1 &
# Ensure kodi has focus (over spotify) -- sleeping could be superfluous if waittime >> 0, but this solution is simpler
sleep 3
wmctrl -a "Kodi"
sleep 6
wmctrl -a "Kodi"
