Using Multiple Monitors and two video cards
 

Hello all I am running Ubuntu 9.04 and I have 3 monitors on two NVIDIA cards. One monitor a Gateway 22" on the FeForce 8600 GS
The other two monitors Gateway FPD1976W on the GeForce 8600 GT card.
I am unsuccessful so far in getting all 3 monitors working. I downloaded the NVIDIA drivers. I checked the NVIDIA X Server setting but I am getting a error message when I try to save to the '/etc/X11/xorg.conf' file.
When I select system/preference and display, I get the popup windows saying 'It appears that your graphic driver does not support the necessary extension to use this tool. Do you want to use your graphic driver vendor's tool instead" I select yes and the NVIDIA X Server window open. If I make any changes I am unable to save the change

I am new to Linux but I really do not want to go back to windows

Is there a button near the bottom of the configuration window labeled something like 'Administrator Mode'? If there is then click on it. It will ask you for your password. Enter your password and click on OK if it is available. This will enable the application to rewrite the system file.

or in a terminal:

sudo nvidia-settings

I tried that and got a popup window "Failed to parse existing X config file 'etc/X11/xorg.conf. when I select ok the nvidia wijdows closed down. In the terminal windows I got the following
'VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Device section "Configured Video Device" must have a Driver line.

Hello I spent so much time on this but I have a bit of success. I can not see my three screens but I cannot drag anything across. All three monitors are the same. How can I get them to be separate and be able to drag from one screen to the other. Here is my xorg.conf file
