The answer is: disper:

apt-add-repository ppa:disper-dev/ppa
apt-get update
apt-get install disper

and then: disper -s to switch to the main screen, disper -S to switch to the secondary screen.

That's actually quite informative. At one time, I used to be a PC gamer and had lots of problems with display when it came to graphic cards. If I ever plan on going back, I'll use your advice if I even encounter that problem. Cheers.
