[i]How did you install Kodi? : According to the instructions of fritsch (Post 1)

Does `sudo systemctl start kodi` work for you from command line on TV? : No - remote from other terminal

Log:
kodi@homeserver:~/.kodi/temp$ which kodi
/usr/bin/kodi
kodi@homeserver:~/.kodi/temp$ cat /home/kodi/.config/openbox/autostart
OUTPUT=`xrandr -display :0 -q | sed '/ connected/!d;s/ .*//;q'`
xrandr -display :0 --output $OUTPUT --set "Broadcast RGB" "Full"
xsetroot #000000
devmon &
MALLOC_MMAP_THRESHOLD_=131072 /usr/bin/kodi --standalone
while [ $? -ne 0 ]; do
MALLOC_MMAP_THRESHOLD_=131072 /usr/bin/kodi --standalone
done
openbox --exit[/i]

Update: I have found my mistake /home/dir was encrypted.
Sorry
