I did use a CD. My idea was behind that was why use approx 1/5th of a DVD when I had CD's and would use 100 percent of it :P.
It isn't acting up on me, per se, the only problem I have is the GPU drivers. I really have no idea what to look for. I tried the ones listed for Ubuntu on the ATI site with no luck... I think I made a mistake in installing the 64 bit version of Ubuntu, but I wanted to use my entire 4 GB of RAM for this project.
I like Ubuntu though. Linux has always been an interest to me, and Ubuntu seemed like the easiest one to learn. I'm going to start with the GUI aspect of it, and then work my way up to using the terminal.
