Thanks for all the help, I have installed the newest package and it runs very well!
As mentioned already the display is a little bit strange: despite whatever parameter I enter as "run lcdproc options" it always circles thru 5 displays and that is very annoying.
But I followed some documentation and found out how to limit that to one display :
'!N' C '!P' '!L' '!I' '!U' '!S' '!T' '!M'
This helps to limit the display to one screen where I remove the '!', really funny but that is it now.
