XDMCP and HP-UX 11i-V1

[PDP-Fan]

I am struggling with a freshly installed HP-UX11i version1. I have here a rp7410 and just installed the OS from the CD set. I'm not a hero on these HP-UX systems, so my Problem might be basically stupid.
I'm trying to get a connection from my Laptop running MobaXterm (highly recommendable free software) through the XDMCP protocol.
But all I get is a black screen.
My questions now:
Do I have to install the CDE desktop manually? is it not included in the UX installation?
swlist can't tell it to me, it only replies with errors.
what else do I have to change to get a x-terminal connection?
