Dual Monitors -Need Help

Hi, I have a 6600Gt with dual heads, with two CRT monitors hooked up to it. I would like to set them up to work in linux. I googled and couldnt find anything I understood . Could you guys walk me through it? Also in my xorg.conf file it identifies my video card as running on a PCI but, but its on AGP, should I change it? Heres my xorg.conf file.

Thanks in advance for any help.


Code:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands:
#
#   cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
#   sudo sh -c 'md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum'
#   sudo dpkg-reconfigure xserver-xorg

PCI 1:0:0 is a AGP slot,
For linux AGP is just PCI on steroids.

If you look into /usr/doc/nvidia (or some similar place),
you find that the nvidia drivers also installed a complete manual (text file)
The manual describes pretty good how to setup dualhead with an nvidia card.
It is not the standart xinerama setup used in X.org but Nvidia's way works.

It is the only way to get xinerama working on a single nvidia card.

Ok, Ill look into that thanks for clearing that agp thing up. Ok, I got em both working, but my second CRT will only run at 800x600, dosnt work at all if I put it at 1024x786. I ran it in 1024x786 in windows. Also, I tryed running guild wars, which I used Cedega to install, and the menus are all squiched horizontaly. I try to reinstall, and cedega wont install anything, is it the dual monitors making it not work? Or is it because their not running at the same res.

I'm running twinview on nvidia Geforce 6600 (PCI-E). Don't know anything about Cedega, so I can't help you there. But getting the nvidia drivers and twinview up and running under Ubuntu is quite easy.

Her's my xorg.conf file:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands:
#
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
# sudo sh -c 'md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum'

_________________________________________________

Use http://ubuntuguide.org/
on howto install the right drivers. Then edit the xorg.conf file as I did. Change the HorizSync and the VertRefresh to match your CRT's. The only different thing is my resolution witch is 1024X1024. I recomend it! Try it out and see.

About cedega and twin view:

I don't think it could work (but I'm haven't tried myself)
Nvidia's TWINVIEW is a nvidia only X upon the X windowing system.
For Xwindows the way to setup to monitors is using xinierama.

Cedega will asume "normal" X behaviour....
Get ready to run into severe compatibility issues.

Yes it stretches, but only for games which let you set abritary resolutions (eg: 4096x768).
I doubt developers of games like GW tought baout anything else but "normal" resolutions.

But you will never find out unless you try:

One of the nicest ways running two displays is to leave all this xinerama and twinview nonsense aside and simply define two devices (two identical sections in your example), two monitors and a layout where both are left or right from each other.

The result is two screens with panel and menu each over which you can distribute your work.

Wow now thats a good idea, then I think Ill be able to play games on only one screen. Could you go a little bit more in depth in what I need to do? Or do you have an instant messanging client we can talk over?

Sorry, am at the wrong place to offer much help at the moment. I got the idea a while back when looking at xorg.conf files for a setup where two monitors, two keyboards and two mice hang off one computer. I guess using this description will throw up a tutorial in google. If I after all do have time tonight I will see if I can be of more help.

The essential bit was two device sections, two monitor sections, two screen sections and a layout which simply defines the two screens as being however next to each other.

I think like this

Section "layout"
InputDevice "Generic Keyboard"
InputDevice"Configured Mouse"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" LeftOf "Screen0"
EndSection

But I am not at a computer with Linux right now to try it out...

I got it working to some extent, my other screen will only work at 800x600, not 1024x768 like it does in windows. This is what causes problems in my games. Guild Wars supports 2048x768 but not mixed. Is there a way to force it to run 1024x768, or am I stuck getting another monitor. (This one is old anyways). Heres my xorg.conf file.

EDIT: I got it to work at 1024x768, I thought the part that said "meta modes "1024x769, 800x600" where the resolutions at which the second monitor can run, I set it to "1024x768, 1024x768" and now it all good. My problem now is trying to get guild wars running across the two screens, which i can do in windows. It wont let me click to change the resolution.
