Works fine now

i fixed my startup script to be like this


start on started hildon-desktop
stop on stopped hal
#stop on stopped dbus
respawn
respawn limit 15 3

script

## get dbus session bus address
sleep 2
PATH="/bin/:/usr/bin"
pids=`pgrep dbus-daemon`
for pid in $pids; do
FILE=`cat /proc/$pid/environ | perl -pe 's/\x0/\n/g'|grep SESSION_BUS_ADDRESS_FILE \
|sed -e 's/SESSION_BUS_ADDRESS_FILE=//g'`
done
eval `cat $FILE`

export DISPLAY=:0.0
exec su user -c "exec /usr/bin/appname"
sleep 5

end script
