I have 4 monitors using NVidia GForce and only 3 work.


I am using the following configuration file: /etc/X11/xorg.conf:

Only three of the four monitors work. If I change anything I lose on of the monitors. There is a plasma tv that is the main monitor; I would like to change that if possible. The system also runs very slow when I have the three monitors enabled. I don't get any special effects. Do you have any advise on how to edit this file so that all four monitors and compiz works.

I am using a Nvidia GeForce 8800 and an Nvidia GeForce 77000 as my video cards. Is their a reason why a video card that supports dual monitors would only show one of the monitors. If I edit the config file the three monitors that work may change which leads me to believe that all of the monitors work. Now, if I could only get XWindows to understand that I have four monitors.

I just downloaded the newest GeForce driver from Nvidia. I am using Fedora 8 64bit Edition and I have a dual opteron system.

Just to say hello...

Woah! I saw you were a newbie (me too), so I thought I'd say hello. Didn't realize you were so well setup and knowledgeable! This is a great site and someone will probably answer you, at the latest, 24 hours. Welcome to the forums.
