If you're going to tamper with a critical subsystem of the installation and refuse to load nvidia's glx module for debugging, then you're not giving us much to help you with. And, if you're that concerned with the closed source GLX module, why don't you just use nouveau? From what I understand, it's good enough for a 2d desktop and minor desktop effects (not even sure about that).
