Use "nvidia-settings". It should be on your program menu and in /usr/bin
THAT sets up dual monitors, as it's a little bit more complicated than
some script can handle. You will have to configure the second monitor,
agree that it is identified and set as expected, then select twinview if
you're using one card/two monitors, position the respective monitors to
their physical location ...which is right and which is left, the second
monitor should come to life and if all appears correct, then you look
down in the lower right corner to the "Save to X configuration file"
button and save it to /etc/X11/xorg.conf. It should ask for your passwd
to proceed. I highly doubt you will set it up any other way. This isn't
hard, but I don't think that xconfig can make all these choices for you
correctly, so it doesn't try. Been doing this long time, it works. :) Ric
