Script personalizado em /etc/rc.local - não iniciando corretamente o X

Question

Eu fiz um script chamado starter.sh:

#!/bin/bash

while true; do
sudo fluxbox & 

sudo -u pi epiphany-browser -a --profile ~/.config http://localhost/index.php &
sleep 2s

done;

Que é iniciado em /etc/rc.local:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

sudo  xinit /home/lustron/Lustron/starter.sh - :0 -nocursor & 2>1  &
sleep 5s
sudo  python /home/lustron/Lustron/sensor5.py  &


exit 0

Em raspi-config, ordenei que o RPi iniciasse apenas um shell, não um servidor X. Como eu posso ver, o rc.local não está sendo carregado durante o início do RPi. quando executo /etc/rc.local manualmente com

sudo sh /etc/rc.local

Recebo muitos erros:

_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/Lustron:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

Ajuda por favor! Como faço para que funcione (para iniciar automaticamente um epifania no modo de quiosque, sei que posso usar

while true; do
 sudo matchbox-window-manager -use_cursor no -use_titlebar no &
 sudo -u lustron epiphany-browser -a --profile ~/.config http://localhost/index.php
 sleep 2s
done;

no starter.sh, mas não está funcionando por causa desse problema no servidor X.
