Triple Monitor setup
Hi, I'm using CentOS and I have 3 LCD monitors in front of me. I initially had a dual setup that worked but now I cannot get the additional monitor to display anything. I have 2 GeForce 9600 GT's, and I have modified the xorg.conf file to what I believe is correct. When I restart the X server, the 2 monitors I used as duals will reboot normally but the 3rd still stays blank.
Here is my xorg.conf file:
Code:

I do have Dual head enabled in the display settings, if that matters.
Thanks,
