I have installed the nvidia driver the easy way. Through repository ftp://download.nvidia.com/opensuse/leap/42.2 on OpenSUSE Leap 42.2.

Though I ask here as NVIDIA says the packages in this repository is maintained and supported by Novell/SUSE.
Code:
The driver RPMs hosted in this location are entirely built, maintained and supported by Novell/SUSE.  
NVIDIA hosts them as a courtesy to Novell, however all problems and support requests related to these RPMs should be reported to Novell via their bug tracking system:

With the SUSE OBS wouldn't it be easy to create nvidia packages for Tumbleweed. I like to update my Linux kernel frequently, but it entails more work needing to recompile the nvidia driver each time. Having nvidia packages built against the latest kernel would be appreciated.

Is there a particular reason why Tumbleweed cannot get nvidia built packages like leap does?
