Allow x-server root login

I have Kubuntu installed with live cd and i wanted to be able to use the user interface "UI" as root user!
So i searched on the net for a solution, and here it is:

1. Open a console terminal and get root prompt
Code: sudo -s
-> Enter your password

2. Find this file
Code: ls -al /etc/kde3/kdm/kdmrc

3. Open it with a console text editor
Code: nano /etc/kde3/kdm/kdmrc

4. Find
Code: AllowRootLogin=false

5. Change to
Code: AllowRootLogin=true

6: Saving and Closing Nano => "Console Text Editor"
ctrl + x ; press y ; and press execute

You're done - Hope it'll be helpful.
