Hello takt1kal!
Yes, if you follow my tutorial you’ll be disabling Intel GPU, which means you couldn’t switch between gpus. However, if nvidia-smi command is missing, it means that you haven’t installed its drivers yet.

Hello, I tried installing nvidia drivers but when I run nvidia-smi, it says it couldnt communicate with driver. I could really use your help. Thanks
