Thanks. I couldn't remember these details any longer.

I don't know how the nvidia driver has been installed on this system. If the
customer used our packages from 

  https://download.nvidia.com/opensuse/leap/42.3

in %post installation we switch to GLX extension and libGL of X.Org/Mesa on an
Intel/NVIDIA system for safety reason. Assuming that Intel is the primary card.
Could well be that then these suse-prime scripts no longer work.
