After many troubles with 12.04.2 LTS, I decided to go with 13.04, which is much more compatible as far as graphics go. However, I have an external monitor that I cannot get to work. It is a VGA, connected to a MiniDisplayPort adapter. The video card is a nVidia 330M. I've tried Googling this a lot, and I just can't seem to get an answer.

It's worth noting that I know much more than the average beginner, but I am not ready to call myself "intermediate" just yet.
