I recently downloaded Knoppix 5.01, and was earlier running Knoppix 3.3. Man!! What an improvement it is.

Well, I seem to be stuck in a problem. In older versions, you could login into root account at login screen by typing "root" and your password. This new version says that root logins are not allowed.

Is there some reason behind this?
How can I login into root with GUI?

Thanks in advance.
