I believe if you issue the command "xhost +localhost" you'll be in business.
For further details check:
man xhost
Unlike my previously successful hard disk Knoppix installations (various versions from 3.1 to 3.4) my latest HD installation (3.8.1) does not result in root being one of the user options for selection once the boot process has finished. I can login as a normal user, and successfully su into root via a terminal window, but if I then try to start Konqueror from the command line I get the following:-
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
konqueror: cannot connect to X server :0.0
How can I run root from a KDE graphical interface using Knoppix 3.8.1, as I am used to doing using Knoppix 3.3?
The rest of the installation works fine, and I am even able to print from a network printer which previously required editing of cups and kde configuration files.
Thanks for any advice.

Thanks for the reply eon. Unfortunately, although the command you suggested works for localhost, it doesn't work for root for some reason. Below is some more output that may be useful for someone to explain what I need to adjust to enable a graphical root environment.
