Press some button on your laptop 2-3 times. Specifically, the one marked "CRT/LCD" or some such.

Microsoft can now handle dual displays, so more modern laptops are capable of displaying different things on the LCD panel and the external connector. It's not always clear whether X can handle it; for example, I've had a Dell Inspiron 6000 for 6 months now, and I still can't work out how to get it to drive the external display correctly. Note that there are many other issues with external monitors, and even more with projectors: many projectors are much more finicky about signal timing, and will just shut off if they don't like what they're given. Again, the Microsoft world has normalized this sort of thing. If you're planning to use projectors a lot (for presentations, for example), it's a good idea to mimic Microsoft timings.
