If you can't get superuser privileges with su/sudo, something is very wrong with your copy. Swapfile use has always worked perfectly for me as superuser.

Beware that quite a few problems have surfaced and then gone away again through the various releases, most of them Linux/X/Debian-related, not Knoppix-specific. Knoppix now is very close to standard Debian, package-wise.
6.7 is out? In English I hope. Thanks guys for all your help. I will start with that!
