Xorg woes

[andrew.walters at cerebrum.com.au]

Hello

I am hoping that this is the right place to request help for such a  
problem - I am attempting to make the transition from Windows to  
FreeBSD so bear with me:

I cannot, for the life of me, get a working X configuration.

I am running an AMD-64 (Asus M2V-TVM) with an integrated VIA K8M890  
graphics chip.

I have installed a working (text only) version of FreeBSD 6.2  
following the FreeBSD installation instructions and have downloaded  
and built Xorg using the same instructions.

I attempted to configure Xorg for my setup but on every test could not  
get a usable screen.

Having done a bit of research and discovering that the VIA chip was  
problematic, I bought a NVIDIA 85000GT because the NVIDIA driver  
support seemed to be much better. Unfortunately, the results were no  
better.

I am also running Windows and have tried an installation of Ubuntu on  
the box with both cards without any real hassles.

I have set the refresh and sync rates amd the modes for the screen  
(have even copied the working "Vesa" setup from Ubuntu) but I still  
can't get a working screen (it varies from completely black using the  
NVIDIA cars to a fuzzy mess using the Via).

If anyone can point me in the right direction, it would be extremely  
appreciated.

Regards

Andrew
