But did not get a response, maybe this forum is the right place.
The demo program show the problem: glXChooseVisual returns NULL.
Local XServer: Nvidia 396.24 and remote host: mesa 17.2 (RHEL 7.5), does not work
Local XServer: NVidia 396.24 and remote host: mesa 17.0.1 (RHEL 7.4), works
The same is true for the system binary “glxinfo”.
With mesa 17.0.1 it shows the “Vendor,GLX extensions,etc…” with mesa 17.2 the whole
output is omitted (only the visuals are shown)
The output from glxinfo on a RHEL 7.4 system with only mesa installed:
$glxinfo
name of display: localhost:13.0
display: localhost:13 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

Then the output from glxinfo on a RHEL 7.5 system with only mesa installed:

When I start glxgears on the RHEL 7.5 remote machine:
$ glxgears
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Error: couldn’t get an RGB, Double-buffered visual
Ok. I can reproduce with nvidia’s driver on my computer and mesa’s libGL on the remote machine. Indirect rendering is broken with this combination. But it still works if the remote machine is using nvidia’s libGL. (All machines run RHEL 7.5.)
Now you have to find someone who feels responsible for this …
