Hi Petter,

thank you for this interesting insights!
I wasn't aware that ldm was replaced by kdm by default.

Could bootmisc.sh be an apt place to start (now Josè's) killer script?

Just wondering: disable kdm?

I had a look at  /opt/ltsp/i386/etc/rc3.d/S20ltsp-client-core 
and suspect that this (conditioned) block of code causes a 30+ seconds 
hang when splash is enabled on our system:

Finally, I wonder how much time & other ressources it takes to open 
12(!) terminals:
