I have Ubuntu 22.04 on MSI laptop with two video card: rtx 4070 and intel. I am a data scientist, and I want to make so that all processes use intel video card by default, and only my deep learning stuff to use nvidia. Below is the output of commands that show my real configuration. In short: prime-select is set to on-demand, but nvtop shows that processes like firefox, slack and others are using nvidia card.
Question: how to make so that they DO NOT use it by default?
