This seems to work now, with a 1:1 picture of alubook:VGA:
xorg.conf snippet:

I'll play with the whole settings a bit more when I have got more time
available than today ... I set all this up in 2 hours or so ... I'm

I wouldn't have managed it in that short amount of time. So thanks a

I'll remember that next time: I had it on for the special effects of
'xboing' (shaking screen :) to take effect ... IIRC
Thanks a lot, Michel, for the lesson, and everything :)
Nice weekend to everyone
Best Regards
