Signs kernel module of proprietary NVIDIA driver on OpenSUSE.

opensuse-nvidiaupdate.sh

#!/usr/bin/env bash
nvidiafile="$1"

# For OpenSUSE systems that are securebooted.  
# You need the package: kernel-devel
# You need your own signing key in mok.  
# sudo su
# cd
# openssl req -new -x509 -newkey rsa:2048 -keyout gpusigningkey.pri -outform DER -out gpusigningkey.pub -nodes -days 36500 -subj "/CN=Graphics Drivers"
# mokutil --import gpusigningkey.pub

# Usage: $0 NVIDIA-*.run

echo "Make sure the latest installed kernel is the same one that is running."
kver="$(uname -r)"
ln -s /usr/src/${kver%-*}-obj/x86_64/default/scripts/sign-file /lib/modules/"$kver"/source/scripts/sign-file
if [ -z $1 ]; then "Need to specify nvidia run file."; exit; fi
if [ $UID -ne "0" ]; then echo "Must be run as root."; exit; fi
"$1" -s --module-signing-secret-key="$private" --module-signing-public-key="$public"

This is worked for me:

Good stuff, thanks! I'm not on OpenSUSE anymore but if you found this maybe others will and benefit from your update!
