Thanks Robert and DRC, I'm able to get glxgears to run without vlgrun to run on DISPLAY 0 over the Remote connection, but then it doesn't show any graphics on my remote display (which is :10), but I get the text output. I can also get it to run using ANSYS's Mesa libraries oddly enough /ansys_inc/v172/Framework/bin/Linux64/Mesa.
I played around with trying to get the right libraries to load in /lib64 /lib /usr/lib and /usr/lib64, but I still wasn't able to get it to run without vlgrun. I am basically following the setup here for XRDP + TigerVNC for Remote Desktop (with the addition that I also had to add ssl certificates to get it to work) http://www.padtinc.com/blog/the-focus/how-to-install-and-configure-xrdp-and-same-session-xrdp-on-centos-6-7-rhel-6-7 That page suggests to add to xorg.conf - Section “Module” - Load “extmod” - Load “due” - Load “type1” - Load “freetype” - Load “clx” - EndSection However, after doing this and rebooting, then vlgrun doesn't work anymore. Anyway, it is working now it seems. I can use VGL_LOGO=1 vglrun glxgears (or glxspheres64 or runwb2) and then I get the VGL_LOGO to appear, which I think means I am getting hardware acceleration.
