Switching my laptop to linux.

[endrien]

Well I don't use my laptop as a main PC anymore so I figured I'd switch it to linux.The only thing I need to know is how to use internet sharing on linux(Probably going with Ubuntu).I currently use internet sharing to connect to my desktop to get internet on it(ethernet)And I use it to get xbox live on my xbox 360.How can I do this?
Thanks
