(This is a continuation of thread: Installing nvidia driver?).

I am able to detect and configure an external monitor using nvidia-settings program. However, when I try to save my configuration, nvidia-settings complains that it can't save to xorg.conf.

It states that: "Default Device" must have a Driver line.

Now, I ran nvidia-settings using sudo, so this isn't a permissions problem. Here's my file (I am typing it by hand, since my ubuntu laptop has all sorts of config errors, created by my overconfident self. :)

Section "Device"

    Identifier    "Default Device"

    Option   "NoLogo"   "True"

EndSection

Do I just add a driver line? And what should it look like?

thanks.
