Dual head display issues with Warty

Hi,
I haven't actually set this up myself, but I am using vga + tvout in
hoary on an nvidia chipset which is similar to what you're trying to
get going.
The first thing I would suggest is to install the official nvidia
drivers. they really do make this much easier. Not sure if they're
available as a package in warty or not, but they're also available
from nvidia and extremely well documented. The only caveat is that
you may not be comfortable with them not being open source.
Once you get those going, go through the nvidia install documentation
and read up on twinview. You should be able to take an example
xorg.conf provided with the nvidia drivers and modify it slightly to
get twinview going. I believe appendix I of J of the install doc
describes twinview. And despite criticisms I've heard about twinview,
lately, it seems to work quite nicely, at least for me.
Hope this helps
Good luck,
Zach
