How to make use of dGPU and iGPU?
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):
- Video editing
- video transcoding
- AI stuff (ollama)
- Machine learning
- Blender
- Steam games
iGPU (intel):
- Firefox (especially YouTube video decoding, it has hw acceleration for that)
- Chrome
- Libre Office
- GNOME
- 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.
You're viewing a single thread.
do u have installed switcheroo-control and how did u install nvidia driver
I did, but that only allows me to run it in the descrete one where it is already running as far as I understand.
okay maybe u bios u need choose gpu mode as 3d accelerator and how u were install nvidia driver also too,maybe u switched priority using nvidia-settings if so switch back to intel reboot pc and then use switcheroo-control ? I am using dual gpu and my main by default is igpu and it was by default from arch installation
Which one is plugged in into your monitor?
I don't,using internal laptop screen as I know dgpu directly connected to HDMI so everything gonna render on nvidia...
