Further difficulties. 

There are too many options that I don't understand on the
nvidia-settings configuration dialog box for X Server Display
Configuration. What is "clone"? What is "twinview"? What is "separate X
server"?

I tried several options, some of which required restarting X. I did so
with Ctrl-Alt-Backspace. Half the time when I logged back in the screen
came up without my Gnome panel settings. Very strange. I don't
understand how I am going to cram my 1680 x 1050 display onto a
projector that will only do 640 x 480.

I ended up disabling the external projector for now. I have my Gnome
panel settings back. Until I figure this out better I am going to leave
it alone. I don't understand Linux that well and I can't afford to
screw the computer up with a project due in two weeks.

If someone can suggest a tutorial on using external video with a T61
with Linux, maybe I can give it another shot later.
