OpenGL problem

Trying to get OpenGL rendering working from within an ssh session to a RHEL7 system from a RHEL8 system. Getting error swrast driver not loaded although it is present in the correct location. Using glxgears as a test.

If I run LIBGL_DEBUG=verbose glxgears it presents an error that /etc/drirc is not found. I can't find anything that suggests how that directory gets installed, what package provides it. It looks like I have all the libgl and mesa packages installed on both 7 and 8 systems, but this just won't work via ssh.

I've found two ways to fix it on the client side - either add a section to xorg along the lines of "Indirect GLX 1" or reinstalling the NVIDIA driver on RHEL8 with the switch "NVIDIA........run --no-opengl-files". Now glxgears works as well as the utility I'm trying to get to work but management doesn't want a client-side fix. They want a server-side fix on the RHEL7 system.

Does anyone know where /etc/drirc comes from?
