In Cheese, are you getting snow, colorbars, or a black screen?

Of the many webcams I have, the Logitech Comm Deluxe always shows
black until I shine a flashlight into the lens to trigger the
aperture/sensor. It takes a couple of seconds of bright light, then
it's fine.

Strange, because that model also makes me look fat with the Windows
driver, but normal in Ubuntu. Well, I am fat, but I mean "fatter".
