When a visualization/viz node has been configured with VirtualGL it requires an X server to be running to provides access for users to make use of the GPU hardware.
Without it, running VirtualGL fails, so it would be useful to proactively check that an X server is running, so engineers can take action if it crashes/fails to start for some reason.
