dual-head issues

I don't have an answer, only an approach...
For several years, I relied on the efforts of others and used their xorg.conf
files to achieve a dual-head display configuration. However with the release
of K/Ubuntu 7.10, the auto X configurator works pretty well. (I'll bet this
would work with some other modern distros too.) Launch your preferred
version from the live CD and then work with the configurator, restarting X
when necessary, to get what you need. Since the configurator is rewriting
the xorg.conf file, once you get there, you can copy it to your hard drive
(you can mount your /home partition) or a thumb drive. As long as you don't
reboot, you can save any changes you make.
Good luck
Paul
