I was trying Ubuntu Studio 7.10. Post the answers to these questions that you had when you get them figured out. It may help newbies like me.
Ubuntu has a web: http://www.ubuntu.com/
They have documentation: https://help.ubuntu.com/
It is not clear on their web what the difference between plain Ubuntu and Ubuntu Studio. I was trying Ubuntu Studio 7.10, so I think that is the same thing as Ubuntu 7.10?
