I have just performed the (weekly) Debian testing updates on my
other computers (the problematic notebook I was writing about is
updated on a daily basis):

 -> another Thinkpad T41, but with intact display and without
    external monitor,
 -> a Thinkpad T420,
 -> a "normal" PC.

There was no problem with any of them  :-)

So the cause of the problem may well be the external monitor, 
or HW acceleration.  How can I find out if this is activated
in the "good" T41?

   Best regards,
