I still have Windows installed and am trying out the Live CD.

The Live Knoppix recognized the Comcast modem and everything worked alright, though there were issues with display functions not performing properly. I have at least 256 Megs of Ram, so that should be enough to accomodate simple things such as display functions. On one website that I visited, only small portions of the screen were showing up. On several occasions, parts of the screen would get whited out and start partially reappearing as I moved the mouse over them. Plus, there were issues with sizing of the screens and the print coming out really small, though that is probably something that can be adjusted easily.

What causes these issues with the display functioning? Is it something to worry about when it becomes an actual full install?

I have limited space on my hard drive, about 2.3 gigs out of 8. I am inclined to just format my hard drive and start all over. Will connecting with my modem be anymore difficult after I format my hard drive?

Where can I find a crash course on the basics of Knoppix/Debian?

Also, is it possible to switch from one distro to another after I take the plunge with Knoppix?
