It is correct. You don't log in as knoppix. You log in as yourself. You will need your root password to access the X Display KDE Control Center module. You were prompted to give a root password when you did the hd-install.

As described in my previous post,

1. log in as yourself
2. start the Control Center (K menu, Settings, Control Center)
3. select Peripherals, Display
4. you will be prompted for your root password. Enter it in the box that comes up.
5. The KXconfig dialogue comes up. change the monitor and/or refresh rate settings to suit your monitor, and/or the screen settings to the resolution/refresh rate you want. Choose something your monitor can handle (it's not perfect).
6. select "Quit". It will ask if you want to save your new settings. Say "Yes". It will then tell you that you need to restart your session for the settings to take effect.
7. Log out, and, from the main login screen, select "Menu, Restart X Server". In a couple of seconds you should be back to the login screen with your new settings.

I would strongly recommend you try this first before you start manually editing configuration files in /etc/X11, which can cause all kinds of problems if you are not careful or are not sure what you are doing.
