I'm talking about an either/or scenario, where by means of a key
combination on the internal keyboard the monitor is switched to internal
or external. Using both monitors simultaneously with different images
on each one (i.e. displaying a web browser in one window and playing
solitaire in the other one) is a whole different thing. If that's what
you want to do, you're out of my league. I have no experience with that.

Well, there's chvt, but that is something completely different.
That's multiple logical (text-mode) terminals on a single physical
terminal.
