Hello all,
Due to heavy the nature of my work I need to run very heavy GPU ML computations on my desktop which makes my whole screen lag.
For this reason I have thought of maybe using the IGPU on my intel cpu for everyday needs while having the gpu only for the heavy cuda applications.
So my question is how can i switch from using the gpu to the igpu? I have tried installing video-linux but it didnt do anything (yes i have plugged the hdmi cable to the igpu), and i dont know how to proceed from here.
Thanks!

video-hybrid-intel-nvidia-prime is what you want. After that, I recommend installing optimus-manager because that way you’ll be able to switch back and forth between the nvidia and the intel GPUs with relative ease should you want that. Please also post the output of mhwd -li and inxi -Gazy.
Thanks for the suggestion, but I dont think I want optimus since i will never use the “graphics displaying” capabilities of my GPU, just it’s computational power.
From my understand prime lets you run some applications, say steam, through the GPU while others more “light” with the iGPU.

There doesn’t seem to be another video card. Are you sure there’s one? Or is it disabled?
The other video card only gets enabled when a display is plugged into it, which I cant do since by doing that it results into black screen. Missing drivers or something.
If I plug the hdmi cable to the iGPU then it will show up, but I can only have a tty.

Well, that is interesting… and strange. Can you determine why it results in a black screen? Anything in the journal?
What is its PCI address? If you have that, you should be able to replace the current Xorg video settings with the following:
Section "ServerLayout"
Identifier "layout"
Screen 0 "integrated"
EndSection
Section "Device"
Identifier "integrated"
Driver "modesetting"
BusID "PCI:<PCI ADDRESS HERE>"
EndSection
Section "Screen"
Identifier "integrated"
Device "integrated"
EndSection
(e.g. /etc/X11/xorg.conf.d/10-integrated.conf).
My guess is the black screen is caused by driver mismatch since last time I tried this I had 2 drivers installed, on the nvidia and the intel one. I guess the nvidia display is disabled if the iGPU gets enabled?
Below are some outputs of when the iGPU is enabled.
