I'm on Arch (btw.) and I have a Intel i5-14600K CPU with a iGPU (UHD Graphics 770) (GPU 1) in it and a dGPU from Nvidia, the RTX 3060 (GPU 0). I have one monitor connected to the 3060 via display port 1.4.

I can see both GPUs in GNOME Mission Center, but hte iGPU has always Clock Speed 0 and Utilization 0. So anything which is done on the GPU is done on the 3060.

I want to seperate what is done on the iGPU and what is done on the 3060:

dGPU (RTX 3060):

1. Video editing
2. video transcoding
3. AI stuff (ollama)
4. Machine learning
5. Blender
6. Steam games

iGPU (intel):

1. Firefox (especially YouTube video decoding, it has hw acceleration for that)
2. Chrome
3. Libre Office
4. GNOME
5. etc.

I wonder if this or at least parts of it is possible. I need the whole 12 GB VRAM on the 3060 for ollama, and the iGPU is just sitting there doing nothing. Is there a way to distribute the work? Do I need two screens for that or something?

It might also be that I'm misunderstanding how the whole thing works or over estimating Linuxes capabilities.
