Dear Markus and Kris,

Thanks for the lead. I will  try the Option "7", but then this
can at best be an interim  solution. I suppose, step one would
be to  go the old classical  style, and boot into  the command
prompt on  console (viz.  remove kdm). Then  set up  things by
hand before  firing X manually with  "startkde"/ "startx". May
work ...
