Run...

After computer restart, we've got surprises:
1) KDE is not running (asks for password, starts to log-in, then black screen, then KDE again asks for password,... )

2) NIS server YP binding takes ~10 min during each start-up. It is not responding to Ctrl-Z, Ctrl-Q, Esc, whatever.
apt-get --purge remove nis

PS It is so very very sad, that apt-get doesn't work for "simple" user
apt-get does work, it's just knoppix that wasn't meant to be installed on a hd.
