If you are using kernel-longterm you have to install e.g. nvidia-driver-G06-kmp-longterm and notnvidia-driver-G06-kmp-default: that way the right kernel modules are built against the last installed kernel-devel-longtermand rebuilt if needed after a zypper dup.
If Nvidia drivers and kernel go out of sync that should be treated as a bug to be reported and corrected.
