Ubuntu 9.10 and iNvidia drivers for dual monitor

This morning i got a problem configuring my dual monitor on my ubuntu 9.10… after had enabled the propetary driver from invidia when i try to write the xorg.conf i got an error from the interface of that driver like : can’t parse the /etc/X11/xorg.conf.

So i opened my shell and i do that on my risks .

1) backuped the original xorg.conf (that function well with a single monitor) lik :

   sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup 

2) i deleted the original xorg.conf

  $ cd /etc/X11
  $ sudo rm xorg.conf

3) i run the nvidia setting with sudo like :

  $ sudo nvidia-settings

4) after this i saved the xorg.conf with the nvidia configuration tool :

5) before restart i checked if the xorg.conf exits and i watched what was happend :

$ more xorg.conf
