dual setup fails

[Gergely Buday]

Hi,

today it happened me twice that my dual monitor setup had failed, and
started to copy one screen to the other and the system started to
freeze. On second time I was able to invoke telinit 3 on my fedora 15
box and later telinit 5 switched back my GNOME3 desktop. I send you my
xorg.conf below. Is this a driver or a configuration bug? I am not an
expert in X config, I copied some sections from

https://wiki.archlinux.org/index.php/Xorg#NVIDIA_2

I have the following chipset:

00:05.0 VGA compatible controller: nVidia Corporation C51PV [GeForce
6150] (rev a2)
