do you see a difference between nvidia-xconfig and nvidia installer?
Because I did not mention nvidia-xconfig (and nobody did in this thread)

this:
NVIDIA-Linux-x86_64-100.14.19-pkg2.run
is installer which will install
nvidia-xconfig
Yast is not using nvidia-xconfig, only nvidia-installer script (unless something changed, but I doubt as sax2 still has problems with proper recognition of 3D)
