Re: libGL.so.1: undefined symbol: _nv000008gl
This error indicates that the incorrect version of libGLcore.so.1 is being picked up from somewhere. Please run `ldd /usr/bin/glxinfo` and see which libGLcore.so.1 it's using. If it's in a nonstandard location, please figure out where the stale version came from and uninstall it.
You might have better luck if you stick with your Linux distribution's driver packages.
