Setting up a Webcam under Linux
In theory, if your webcam conforms to the UVC standard, then it should be a case of simple “plug and play”: plug the webcam into the nearest USB port (-see the USB definition if you are unsure) and you are ready to go!
Nearly all manufacturers also ship fancy software with their webcams, but this is invariably for use with Windows only, so you can deposit the CD directly in the nearest recycling bin if you are running Linux.
The good news here is that said software is almost always just gimmicky effects or the manufacturer's own video calling software (-which no one else would be using unless they had the same webcam as you), so it's not needed anyway. Incidentally, the technical term for this is bloatware : software that just fills up your disc and serves no real purpose.
