Well, you just have to remember that on a basic level, windowing systems are very similar in form and function, the problem lies in the menus, nomenclature and such. You won't find a Control Panel, but you might find a Control Center. It will take a little exploration and experimentation to get a feel for it. If you were thinking that everything was the same as winders then of course you were disappointed.
But it really isn't that hard; just different.
I just stuck my knoppix disk in that i had from a few months ago into a different computer here on my DSL and that Knoppix live cd cant find any ethernet drivers.
