I played with nvidia-settings tool and got somehow a TwinView (dual 
monitor) setup running. My main monitor is running on 640x480 and my 
second monitor is running on 1280x1024. 1280x1024 should be the same 
resolution on both monitors because both monitors are the same models.

The main monitor is connected on the analog VGA port and the second 
monitor is connected on the DVI port with a DVI to VGA adapter (that 
means the second port is analog VGA, too!)

I checked the xorg.conf file and found this interesting line:
    Option         "metamodes" "CRT-0: 640x480 +0+0, CRT-1: 1280x1024 
+640+0"

I changed it to:
    Option         "metamodes" "CRT-0: 1280x1024 +0+0, CRT-1: 1280x1024 
+1280+0"
and the second screen went black :-( .

The TwinView (dual monitor) setup was working fine in Ubuntu 7.10 with 
the restricted nvidia driver which was available there but it dose not 
work anymore with Ubuntu 8.04 :-(

Any pointers advice or help are really appreciated.

Here is my full xorg.conf:
