[bf1942] nice'ing processes

Screen -D -R pid.tty works, too.

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
