Thinkpad T410 nvidia nvs 3100m - Tumbleweed Nvidia how/what to install?

Tumbleweeed is running fine in my old Thinkpad T410 Nvidia NVS 3100M with Nouveau for the past many months.

Read somewhere that there is an official repository provided at

I added the repo and I “think” I added some nvidia package, did a zypper dup and reboot.
I am now left with a laptop in a continuous reboot loop (unable to get to the login screen) - this I will fix myself.

Anyway, really appreciate if anyone can help and advise what is the proper steps that I should do to install the nvidia driver after adding the official nvidia repo.

Many thanks in advance.
