Hi Thomas,

I upgraded last night and had the same error message when I tried to
run the Gnome Display tool. What I did was NOT to run the
'nvidia-confg' tool, because this is an nvidia tool which bypasses the
existing and much developped/tested Ubuntu tool. So I prefered to use
the Ubuntu tool instead (System->Admin->Hardware Drivers), then I
selected the latest / '180' Nvidia driver, clicked on "Enable",
restarted (since you can't restart X by hand anymore using the K/B) the
computer, and hey presto, the nvidia config tool now can start, letting
me configure everything. 
Problem: although it configures everything just fine, there is a
bug/problem somehow: it complains that it can't write to xorg.conf (NOT
a permission problem), hence configuration will be lost when you
log-out :-/
So you need to configure xorg.conf by hand, like in the old days :-/
Luckily I did an 'in-situ' upgradde rather than a fresh install, so the
upgrade tool kept a copy of my old xorg.conf... so I just used this one
insted of the (pretty much empty) auto-generated file.

Hopefully nvidia will release an updated version of their tool, to fix
this bug, as it renders their config tool rather useless ! :-/
