Hi, and welcome to LQ.
The first thing to do is to learn to use your favorite browser to search the web for answers to questions you may have. Unless you are trying to get bleeding edge tech working, most questions you may have are already answered and available on the web. You could have your answer in seconds instead of waiting for someone in a forum to answer your question.
Case in point, your post. It took me about 5 second to find these instructions for Ubuntu 10.10, which shouldn't be too different from Ubuntu 10.11.
