How to Disable and Enable the NVIDIA GPU from command line?

Asked by Umesh

I am using the OS Ubuntu "18.04.5 LTS (Bionic Beaver)" on an HP machine with NVIDIA graphics card. My applications can run both with and without GPU. I want to test and compare the results on the same box with and without GPU. So I want to run the test on the box once with GPU and once run the same test again by disabling the GPU and compare the results.

So, I want to understand how can I disable the GPU from command prompt and after the completion of the test again enable the GPU.

Please help me with the steps/commands.

The recommended way of usage is having the NVidia GPU disabled and to enable it for a single command with https://wiki.ubuntu.com/Bumblebee#Usage

You might also need to do the steps in https://itectec.com/ubuntu/ubuntu-bumblebee-doesnt-work-on-ubuntu-18-04/

If we can have command that can disable and enable the GPU, that would be great.
