Hi, I have an Optimus laptop (amd igpu & nvidia dgpu). I already have the correct drivers for running the nvidia, I use prime-run to run the application I need using the dgpu however when attempting to do the same for Unity it is a bit different, as Unity has evolved and now they use a “hub” which then allows you to run the project with the “editor version” you need and thus the hub is what launches unity, personally if you ask me it’s all messed up unity made it way more complicated than it needs to be.
Anyhow I already posted on their forum and waiting for an answer, I as well found someone who said he tried something similar to bypass the hub and launch the editor directly but I was unable to follow through till the editor launches, here is the link: https://forum.unity.com/threads/unity-editor-running-with-prime-run-on-linux.1128050/
edit: I as well tried the optimus-manager, while it got the dgpu working on everything it’s not the most efficient as the dgpu will be the only gpu working and not use the hybrid mechanism that I need.
here is the inxi output:
