can't I just set the resolution in KDE and It'll change it when it runs? Because I don't care about how big the boot text is

Oh, and I realised the loggin in as root thing last night, my mistake to not try that.

One other question: Is it worth logging into a personal account or should I just always log in as root. Since I am the only main user of the computer, you know. I noticed the root account doesn't have the hard drive icons on the desktop as the personal account does (by default any way). Until then I'm logging into my personal account

EDIT: and about the undefined video mode, I'm reinstalling linux through the knoppix-installer script. I think it just takes your cheatcode settings from when you boot knoppix and puts them in the lilo config automatically. So I used vga=normal this time and it should work.
