Re: Nvidia GLX doesn't work
You should remove the line 'Load "dri"' from your xorg.conf. Further xdriinfo doesn't work with the nvidia drivers. Try to run glxinfo and see what it shows. Further figure out which libGL.so is actually used by opengl programs. I belive that on gentoo there are symlinks from /usr/libGL.so and friends to the real libs. The real libs are in that nvidia directory which you showed but this doesn't say that they are used.
