You are getting the idea.

The problem (or benefit depending or your point of view) with Linux is that modules
(i.e. drivers) are not supplied by the manufacturers of the video cards, audio cards
and what have you, but by the Linux developers, who do it for free. This means
support for infrequent cards is sometimes poor. Things also depend greatly on the
Linux distribution. Several years ago I used SuSE Linux 7.3 (I think) and their setup
tool (Yast) knew the G200 out of the box. No problem. A few years later I had to
switch to RedHat 9.0 (office pollicy) which didn't know about it.

You already have one head working so the X-server is functioning. You only need
to tell it to use the other heads to, and in which configuration. I can only guess the
X config file for XFree86 6.8.1 isn't too much different than for 4.3.0. So just put in
all the required sections in your config file and try startx. If you still can't get it to
work, I hope someone with more up to date (Fedora/X) knowlegde chips in.

BTW, do you knoppix? This is a live Linux system on a CD. You can download
the CD image from the net. Many people use it just to find out how to configure
their devices, since knoppix knows many cards, although I don't know if it
knows the Matrox G200.

ok i now have 2 choices, reinstall or figure it out. I tried to modify the xorg.conf file myself putting in sfuff llike my moniitors as best i could in the server section. since i don't know the syntax for this file I was in hope mode. when i boot up it gets to the point where is says somethign to the effect of (sorry im not on that computer now and didnt write the exact message) loading kernal and then it just freezes.
this is right after it says press I to enter interactive setup. I have pressed I and not pressed I and neither helps. Now, if I have screwed up my xorg.cong file isnt there a way to tell linux to boot but not into x? that way i can from a command line copy my backup xorg.conf file to the one I modified that (I'm assuming here) is now preventing me from booting? ARGGGGGGG. thanks in advance.

Do the text mode consoles work? Try Ctrl+Alt+F1...F6
If it doesn't, boot up the machine using a rescue cd or floppy (carefully follow instructions).

In /etc/inittab there should be a line like:
x:45:respawn:/etc/X11/prefdm -nodaemon
Comment this out. Now on boot the system won't start X automatically.
Now you have to type startx (or startx -- -layout <layouttotest>) (see man startx)
to start the X server. Ctrl+Alt+Backspace to exit the X-server (you don't need to
reboot each time :-)

Looking at I think the xorg.conf
uses the same syntax as the old XF86Config. On your box man xorg.conf should
give you the syntax I hope. If you weren't new at this I would tell you to RTFM. It's
all in the manual pages, but one hase to learn to read/study them.

Go step by step. I would first set things up for single head (you had that working),
then multiple head in clone mode. If the latter works, its likely the other modes work
too. It shouldn't be so hard really.

Post the x error messages and x config file when it doesn't work.
