Run kate as root

[The Japanese Geek]

I am trying to run Kate as root. After looking at the FAQs, I detemined I needed to do
sudo kate
Unfortuetly, this leaves me with

kate: ERROR: KUniqueApplication: Can't determine DISPLAY. Aborting.
Normally I would simply log in as root, but this is not possible on KNOPPIX.
Any Ideas?

Your shell prompt indicates you were already root while issuing the suggested command, which should have been typed from a regular, non-privileged shell.

There seems to be a specific problem with kate, though. Kwrite, xedit or mcedit all work.
