Eu tenho um script que escuta na porta 12 e invoca o xbmc ao receber um pacote wol. Ele funciona perfeitamente quando eu inicio o script diretamente da linha de comando, mas nada acontece quando eu deixo o upstart executá-lo, nem mesmo grava no arquivo de log. Alguma idéia por quê?
EDIT: Adicionado log no final do segmento
Aqui está o script xbmc seguido, mas o script inicial:
#!/bin/bash
UDP_PORT=12 # Change this if you need to run this on a different port, just remember to update Yatse's settings as well
RUN_XBMC_AS=usrname # Change this if you need to run it as another user
LOG_FILE="${HOME}/xbmc-autostarter.log"
START_PHRASE="YatseStart-Xbmc" # Do not touch this, unless you know what you are doing...
# The following block checks if the user running this script has the required privileges to listen on the port specified above
WHO='whoami'
if [ "$WHO" != "root" ]; then
echo "Unprivileged users may not evesdrop on ports. Cannot start unless running as root." &>> "${LOG_FILE}"
exit 1
fi
echo "Listening on port $UDP_PORT for Yatse remote start command" &>> "${LOG_FILE}"
while [ true ]; do
# Wait for a packet to come in from Yatse
LISTEN='tcpdump "udp port $UDP_PORT" -A -c 1 -i wlan0 2>&1 | grep -o "$START_PHRASE"'
echo ${LISTEN} &>> "${LOG_FILE}"
# Make sure that we received the right command
if [ "$LISTEN" = "$START_PHRASE" ]; then
#echo "Starting XBMC as $RUN_XBMC_AS"
# Start XBMC using sudo -u to run it using the username above
# If you need to you can replace the xbmc command below with xbmc-standalone if you are not using a window manager
sudo --user=$RUN_XBMC_AS xbmc &>> "${LOG_FILE}"
fi
# Sleep, to be nice, for unwanted rogue processes writing to our port
sleep 1
done

Acho que você precisa exportar a exibição do usuário no script para saber qual exibição usar. Normalmente, a exibição padrão do primeiro usuário X é definida como :0 .
Tente adicionar export DISPLAY=:0 ao topo do script:
UDP_PORT=12 # Change this if you need to run this on a different port, just remember to update Yatse's settings as well
RUN_XBMC_AS=usrname # Change this if you need to run it as another user
export DISPLAY=:0
