Setup script fork for Leap 15.6 with CUDA-enabled GPU driver install

DAK404 has a really nice setup script for Tumbleweed, and I wanted one for my use case (Leap 15.6 and CUDA-enabled GPU use). So I forked DAK404’s OpenSUSE script; my fork is here.

It’s working well so far for me, but is there something I am doing that’s dumb (I know GPU and display drivers can be tricky to configure), or something I could do better?
