Guess what. I  used the second method you mentioned below

i see  your method seems much easier.

Funny is that it seems to work fine for the fglrx-gears and for opengl 
applications for Qt. It just doesn't work at all for the vtk applications. 
All I get is random pixel colors in the renderwindow that opens.

Is there an easy way of removing all the stuff i did under the other 
instructions, or should i just reinstall debian. (I am getting good at that). 
I will try to just remove the different debs i   created and installed under 
the other method, and proceed from there....

I also didnt understand the LD_PRELOAD concept, if you could give a little 
more detail. I guess that the xfree86-4 config file will also be helpful.
thanks
