I think I figured it out finally. I only can get it to work using
vglrun runwb2 Previously I had LD_LIBRARY_PATH to include /ansys_inc/v172/Framework/bin/Linux64/Mesa. I think that was overriding some of the NVIDIA drivers or something. Now it runs and doesn't crash and no errors. Why can't I get glxgears to run without (vglrun glxgears). Is it not compatible with NVIDIA's OpenGL libraries? Thanks.
