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,
Petra
