[Novices] Problems X After Install

[Kevin Wixson]

I have installed Knoppix on computers before, and never had a problem. 
Now, I have this older computer I want to give away to a needy family 
and have Knoppix running on it, but the install is giving me trouble. 
The install completes, but I can't get it to boot into X, and once I log 
in at the text login prompt and type "startx" it blinks, coughs and then 
gives up with no X. I can't see anything in the messages that indicates 
the problem, but I'm not very good with this stuff.

The computer is a Gateway, 350Mhz Pentium II with 128MB RAM and a 10GB 
HDD. I have a 500+MB swap partition configured. Knoppix 3.8.1 and 3.7 
both work beautifully when run from CD on this computer. I'm installing 
with the "Beginner" option of the knoppix-installer script, for a 
multi-user env. with hardware detection.

Where do I start?
