I don't mess with GUI's much so if you are uncomforatble editing your
xorg.conf, just disregard the following.

Following is what I cobbled together for my laptop for doing just what
you want.  (Normally one wants a clone, not an extension of one's
desktop when one is using a projector.)

I don't pretend to be an X config expert but the following does
work (for me). More comments after the code.

Here's how this is used:

I normally just run my laptop w/o a second monitor so I have never
booted with a second monitor hooked up.  I say this because, based on
some traffic in another thread, if you do boot with the 2nd monitor
hooked up, then the "Fn-CRT/LCD" key may come into play (at least on a
laptop) and with the above setup it does not.

My laptap panel is a 1920x1200 LCD.  When I need to make a
presentation I plug in the VGA cable from the projector and hit
"Ctrl-Alt-Fn +" (that's control-alt-Fn `+') to switch modes from the
first metamode (DFP alone) to the second one (DFP, CRT).  "CRT" does
_not_ mean you must have a CRT hooked up (contrary to what Lonni
Friedman seems to believe). It is just the device on the other end of
the VGA cable.

If you're using a regular keyboard (not a laptop kbd) then there's
often an explicit keypad with a + and - keys.  In that case leave off
the the "Fn" (i.e. "function") part of the sequence above and use the
keypad + and -. The + atop the = will not work here.  (See the "Modes"
section of the xorg.conf man page for more on this).

With the above recipe, I see the desktop at full resolution on my laptop
and the upper left 1024x768 rectangle of it on the beamer.  To switch
back I use "Ctrl-Alt-Fn -"

If your external device is a modern multisync CRT or another FPD that
can be driven at 1920x1200, then I see no reason that the above
(mutatis mudandis) should not give you a clone of your entire desktop.
Or you can run your laptap at a lower-than-native resolution to match
the output device.  That of course will result in a degraded laptop
display due to the resampling that must be done.

One more thing:  my xorg.conf file came from running livna-config-display
to get the basic entries right. I then added the TwinView stuff myself
and dorked around till it worked.  Of course I also studied the
(excellent) Nvidia driver documentation which you shd. find by running

locate -i nvidia | grep -i readme

from the comline (assuming your "mlocate" database is up-to-date).
On my system this prints:

/usr/share/doc/xorg-x11-drv-nvidia-100.14.19/README.Fedora
/usr/share/doc/xorg-x11-drv-nvidia-100.14.19/README.txt

The first file is useful basic stuff.  The 2nd file is where all the
action is.  Spend some time reading it and you will be an expert. :-)
