Hi Ric!

The little I know of virtual frame buffers is that they are used to
test hardware or provide a virtual KVM for an X client.   I think you
simply want to get X11 running.  See:

http://en.wikipedia.org/wiki/Xvfb

For that I would be looking at /var/log/Xorg.0.log and
/etc/X11/xorg.conf (along with /var/log/messages and /var/log/dmesg).

I do hope you find what you need.
