Newbie needs help making 3 monitors work
 

I just installed fedora 5 on my computer which has 3 monitors working in xp. I have a matrox g200 card that supports up to 4 monitors. Presently my main monitor works fine but my other 2 just have colorful streaks across them. I went to matrox's site and looked for new drivers (not that I know how to install drivers on linux yet anyway :) and the links to 3rd party drivers were either moved or pointed to sites that had nada to do with drivers. Any way to get all me monitors working with this card? My education starts.....now!!!

Please post your xorg.conf file (found in /etc) and any startup messages from your video card (dmesg | grep matrox)

OK first my cryptic xorg.conf file.............

Thanks in advance...................

Ah so I stumped the forum? Help a newbie linux brother brothers...

No, just cant always reply the instant you post. A little patience goes a long way.

Now there are two ways to go from here, but in either case the first thing to do is backup your xorg.conf file.

First way is easy, but may not work. Start computer in runlevel 3. Login as root. Type X -configure, which will generate a test xorg.conf file in /root/. TO test it, type X -config /root/xorg.conf.test (file name from memory, it will tell you what to type after you have run X -configure).
If it works, cp /root/xorg.conf.test /etc/X11/xorg.conf

If that doesnt do the job, then we need the output of lspci. (if in runlevel 5 you need to type /sbin/lspci)

thanks, I tried, went to runlevel 3 and then typed the command but it didn't work. my screen went blank and I had to reboot. When I rebooted and looked for an xorg.conf.test I could not find it (I did an updatedb first...I guess I go to lspci next?

yeah. the output of lspci tells you the bus id of the graphics cards (matrox cards tend to identify as separeate cards, even though they are only one physical card)

Thank you here is the cryptic lspci.....

Ok... you need an xorg.conf *something* like this:

But a warning: make sure you backup your xorg.conf file before you do this, as i dont have a matrox system to test it on. It should work, but i cant easily test for typos so be careful.
