conflicting OpenGL libraries are installed in a location not inspected

third-party OpenGL and third-party graphics driver packages.

How could this be solved?
(I have an AMD64 and I'm using the 64bit nvidia installer)
Well, the problem hasn't been totally solved. The computer freezes (completely) randomly. Is there a way to install OpenGL 32bit compatibility libraries?

for my xorg you can look here:
