Comment # 1 on bug 1178102 from Hans-Peter Jansen

You seem to have missed the SUSE-NVIDIA-GPU-rendering.txt, more specifically:

<<<
Please add any user, that want to use NVIDIA GPU rendering, to the video group:

$ sudo usermod -a -G video <userid>

Now set up CUDA environment, e.g. in ~/.bashrc or in /etc/profile.local:

export
PATH=/usr/local/cuda-10.2/bin:/usr/local/cuda-10.2/NsightCompute-2019.1${PATH:+:${PATH}}
export
LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64:${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
>>>


Adjust to your installation. That file gives troubleshooting tips as well.

Let us know, if you get it to work.
