about using screen:
'screen -ls' produces some output similar to this one:
dea at p15102942:~$ screen -ls
There is a screen on:
2610.pts-2.p15102942 (Detached)
1 Socket in /var/run/screen/S-dea.
Watch '(Detached)' !! I haven't tried it yet, but I guess this might be your
problem. Maybe the use of screen in your startup script doesn't leave the
screen session detached but instead attached. If so, you could use 'screen
-d <sessionname>' or if this doesn't work 'screen -D <sessionname>' to
detach the session where '<sessionname>' is the complete session-id (here:
2610.pts-2.p15102942). After that either call of 'screen -r <sessionname>'
or <screen -R <sessionname>' should work.
If all this won't do, you could try 'screen -D <sessionname>' to force
detaching of the session and 'screen -r <sessionname>' afterwards.
If I might suggest to rtfm in the future - starting apps under different
user contexts: man sudo || man su && http://tldp.org/docs.html#HOWTO
