dual monitors

["LIBERTI, ROBERT D (SNETCOMM)" <rl3136 sbc com>]

Can someone help me get past a stumbling block or two?

I want to set up dual monitors.  (I have this working when I boot this
computer in Windows 2000)

For RH7, I found the Xinerama-HOWTO page.  
I'm in over my head a bit.  I got to the point where it tells you to XFree86
-scanpci
I couldn't run that while in X windows, so I did a shutdown now to get to
single user mode.  (was this the right way to get out of X windows for
this?)

After I got the information I needed, it tells me to make sure I have the
monitors configured the way I want them.  So, I typed
/usr/X11R6/Xconfigurator, and after 3 screens it fails with the "Server
doesn't exist, can't continue." message.

I tried searching for that message and Xconfigurator I got the following
page:
http://www.redhat.com/support/manuals/archive/RHL-5.1-Installation-Guide/man
ual/doc119.html

So I tried what it seemed to be a good stab at it:

cd /usr/X11R6/bin
ln -sf xserver-wrapper ./X
cd /etc/X11
ln -sf "../../usr/X11R6/bin/XF86_SVGA" ./X

It didn't find my Xconfigurator problem.
I'll keep guessing, but any information would be greatly appreciated!

Thank you.
