Hi,
it should work out of the box with the current kernel!!. Have you tried just plugging it in to see, it should work with Skype, Cheese and other video progs no problem!!.
What model is it??. There are a number of different ones!!.
You should have the graphic card addtional drivers installed which you can do via the control center (Intel drivers are automatically installed!) and also have your system fully updated!!.
