  This was a long time ago, so I may not remember all the details.

I was trying to report it under against an xserver problem. Sorry, if I 
made it confusing.

Yes the problem is still present, but it is not ultimately an nv 
problem. However, the problems that surround nvidia driver installations 
obscured the real reason. The problem turns out to be that neither the 
new X configeration system, nor the old auto generated xorg.conf can 
cope with dual video cards. To solve the problem superficially, if you 
have an xorg.conf file, the device section needs a line specifying the 
buss ID. For example in my configuration the device section is as follows.

Section "Device"
     BUSID          "PCI:4:0:0"
     Identifier     "Device0"
     Driver         "nvidia"
     VendorName     "NVIDIA Corporation"
EndSection


Without a BUSID it causes the xserver to fail. I found the solution in a 
how to:

HowTo:NViDIA 185.18 Drivers in Ubuntu 
(http://ubuntuforums.org/showthread.php?t=1125400),

which was really useful and informative. The only thing to note is you 
don't have to take the secondary video card out to find the correct bus 
ID. You have a 50:50 chances of getting it right the first time and if 
you are wrong a second reboot is much faster than pulling the card out.

The only other problem is that the graphical installation program will 
not run, well actually that was the main problem originally. It fails 
because it uses the default info from the CD, which obviously does not 
have a BUSID specified, and the xserver fails. However, the alternative 
text based installer will now allow you to install and then you can fix 
the configuration manually. I have the nvidia drivers installed, but the 
fix also works with the nv driver.

I have no idea how to fix the problem in the new configuration without 
an xorg.conf file though.
