I installed 5.1.1 on my HD. And could not config the networkcard (see post in Hardware problems). The SU-mode won't start.

However I now succeeded to activate the networkcard, and access the internet (and the Knoppix-site).

On the KDE-button (left-down),
select Utilities
then Root Terminal
the root password is asked, after some time a terminal-window appears
type Netcardconfig
one question was asked (eth0 ?), I confirmed this.

Then networking is active (as you now see through this message).


However all other functions which require SU-mode, still react with a SU-error.


Hopefully you can use the above (and a solution for the further SU-mode problems will come along)

Best Regards
