Hi,
Just want to note that the nvidia ftp repo for opensuse 13.1 is up on ftp://download.nvidia.com/opensuse/13.1. It is not yet listed in the opensuse wiki for the additional repositories but I am sure that the wiki maintainer will be adding it to the list soon.
However, on a slightly down note, if you are running opensuse 12.3 then you will find that your nvidia repo has disappeared. All of the dirs and files under ftp://download.nvidia.com/opensuse/12.3 are gone. Oddly the 12.2 repo remains intact. Probably just a PEBKAC issue (moved files instead of copied files perhaps).
I am installing the driver now… hope it all works!
As always, have fun.
Cheers,
Ron
