Alright, I got the root PW set up. I tried to log on with the GUI login, but it said root logins arent allowed. So I went to the Console Login. I entered root and my PW for it, and now I'm at this prompt:
root@kubuntu:~#
I typed "startx" and I'm at a desktop. Not the one I set up, which shows me that I am logged in as root! I went to the Konsole but that wouldn't let me do the eth0 thing, so I went to Run Command... and typed in the appropriate commands. Now, it's not grayed out, but I can't seem to get it to enable. I'm on my sister's computer, and she's getting increasingly ticked at me, so I'm going to try a couple of things and take a few snapshots.
