Make sure you have installed
kernel-source
gcc
make

Now download the latest Nvidia driver:
Place the file in your /home/username

Now restart and at the boot screen, pause the boot by moving the down button, then move back up and clear any text in the boot arguments by holding backspace. Then just type the number: 3

At the login
Type “root” then enter and then your root password and press enter.

now type
cd /home/username

*Now remember you can use the {TAB} key to auto complete
so type:

sh NVIDIA{TAB}
and the whole file name should auto complete
eg: sh NVIDIA-Linux-x86-173.14.09-pkg1.run

Follow the installer and let it compile the kernel module for you.
Say Yes to everything
Use TAB to move around
reboot

you can also use 1. click installation.

NVIDIA - openSUSE

I don’t think the OP has an internet connection, so that could be an issue
