[vtkusers] Xlib: unexpected async reply

[Carlos Martínez Burgos]

Hi again.

I think that the problem is not the code, because it runs without problems 
on my desktop PC. The problem only arises when I run my program on a 
laptop PC.

Furthermore, some time ago I had another desktop PC with NVIDIA graphic 
card, but it seems that the RedHat installation puts a default non 
accelerated driver. In this case I had problems too, but then I downloaded 
the a driver from the NVIDIA web site and it was resolved. This makes me 
think that the problem is on the X drivers, but I'm not sure.

What do you think? Has somebody the same problem?

Thanks.
