Hi, I submited this to the fedora-desktop-list and was instructed to ask here. So I just subscribed to this list. I installed a fresh copy of FC3 on my machine. The default nv drivers work fine. But I can't get dual head working with nv drivers by editing xorg.conf. "system-config-display" does not do any thing when I select "Use dual head" and click ok. Then I cancel to go out of the screen. So I do a init 3 install the NVidia drivers from the site. Change xorg.conf and then do a init 5 and my dual display works fine. But when I reboot the system it does not work. With out the intial graphical part I can go upto the login screen and then when X starts it says that displays were found but non have a usable configuration. Please note that I can use the below configuration file and work on the system with out rebooting after the instalation of the drivers from the NVidia site. My Card is Asus V9400 Gamer Edition which used NVidia "MX 4000" GPU. My xorg.conf is as below.
