Oh i see, sorry I misread, I think the way you do it is like this
# cd /etc/runlevels
# cp -r -P default custom-runlevel
# cd custom-runlevel
# ls -l
Now just remove the services you don't want and then run rc custom-runlevel
, this will start all services in custom-runlevel and stop all services not in it (except for boot and sysvinit). If this works then you can add that line to your .desktop file
