Sure you’re having an Internet connection? If so:

Start Yast - Software - Software Management. Pick Configuration - Repositories.
Click Add - tick Community…Repos - check NVIDIA - continue and OK to go back to Software Management. The driver should be selected for automatic install.

Get back to us if you run into trouble. I can give you a walkthrough to install the driver ‘by hand’.

I try add Repositories but it same show Download failed:


I looked at the URL, it’s there and the folder contains the …DU.gz file.

Looks like there’s something wrong in your Yast. Start the whole thing again, disable all repos except the one for the install media.
Then reinstall all yast and zypper packages.

This matter has to be solved first, before you can get to installing the NVIDIA driver.
