Can not login to CDE -- only Fail Safe Session permitted

I am a hobbyist with a very old machine I have been trying to get up and running. I have an HP 9000/C240 with 1G of RAM and 3-8.5G HD. It is configured with 1G SWAP/DUMP. Currently only one drive is in use via LVM. I have not gotten around to creating more volumes just yet.

It is running HP-UX B.10.20A 900/782 two user license
This is a new install, and I am open to installing again. The problem I have is that when I try to login as root into CDE a core dump is produced after splashing the copyright information and the system immediately logs me back out. I can login to Fail Safe Session and run SAM just fine.

The system is configured on a network, and when it boots nothing is failing. When I login Fail Safe mode I can ping addresses on the Internet just fine.
Previously I had installed the OS with no networking. When I had done this I could login to CDE just fine using a wide number of accounts and shells.
I noticed that when I login as root using the Fail Safe Session, who reports that root is logged in twice, once as console and once as PTS/0 the console session is just idle.

I have created other accounts using SAM and then attempted to login to one of them, in all cases I have to use a Fail Safe Session.
I am interested in hearing thoughts regarding what can cause the system to produce the core file and then prevent me from logging in. Could it be the wrong terminal type? I am not sure how to check but I have an HP A4331D monitor on the machine.

I am very new to UNIX administration so please be specific when you ask me what the log files say.

Thank you in Advance,

No HPUX gurus out there today? I cant help you much with workstations since I dont know much about them except that I cant remember if at the time of my 712 and 715 if you could be root in graphical... (hpux 9.05 and 9.07) I have the 10.20 CDs but never found the time to upgrade... at the time I had a terminal connected as console (reason of my doubts...) What I remember after is that if you dont open a console somewhere it displays on your current screen so you had to open a window that gets the console output:
xterm -C -T console &

I remember HP saying it can be tricky in setting the correct display (vertical/horizontal frequencies...). Does it display at all? I mean do you get the graphical CDE login prompt? (then when you connect it fails.?...)

Thanks for the reply,

Yes I get the graphical CDE login prompt.

And it was working fine before you added network?

Yes that is correct.

How did you define hostname?
(If using SAM, I think there was a bug in 10.20...)
What does
file core

File core revealed the following:
Core: core file from ‘dtsession' received SIGSEGV
I defined the hostname during setup.

I found some other useful information in my .dtprofile located under /home/dirk
The revision on the .dtprofile file is 1.7 and in short it says that if you have the issue that I originally described then check both /home/dirk/.dt/errorlog and /home/dirk/.dt/startlog for errors.

The contents of /home/dirk/.dt/errorlog are as follows:
.... (date and time)
Workspace manager I/O error on display :: :0.0
The contents of /home/dirk/.dt/startlog are as follows:
X connection to :0.0 broken (explicit kill or server shutdown)

On a side note when I originally gave my machine a host name I used an upper case letter to begin the host name. When I later did an ‘/sbin/setparms hostname' that utility advised not to use upper case letters in host names so I changed my hostname to all lower case. I am still having problems.

Thanks for all the help so far!
