I am trying to run glxgears on a remote Linux server using XQuarts 2.7.11 on macOS Mojave (10.14.6), but I get the following error:
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Is this issue due to the fact that the OpenGL version on my MacBook is 2.1, or is it an issue with OpenGL on the Linux seerver?
I need OpenGL 3 or 4 in order to run Unreal Engine on the Linux server.
There could be a number of causes. First off, if you are using Ubuntu 16.04 as the remote server, try to delete off the mesa version of libGL.so
$ sudo rm /usr/lib/i386-linux-gnu/mesa/libGL.so.1
Basically just look for different versions of libL.so and remove those unneeded or outdated
$ sudo ldconfig -p | grep -i gl.so
If you are using Steam on Linux, there is a specific issue where you need to use libnvidia-compute-418 and libnvidia-gl-418
Note that on some systems, the Mesa version of LibGL might be named something like d /usr/lib/x86_64-linux-gnu/libGLX_mesa.so.0.0.0
