Re: Force every app to use iGPU instead of dGPU on laptop.
Per device sensors aren't too reliable to non existent on most laptops. If 10 watt is the overall power draw of the system I don't consider that too far fetched from an technically disabled card stand point

Re: Force every app to use iGPU instead of dGPU on laptop.
To answer your question: running on my NVIDIA GPU = rendering using it and being reported via nvidia-smi
Not sure why that wasn't abundantly clear.
Because that is by no account of yours what is happening (well, before you swapped the GPU order and found yourself what happens when you're *actually* running on the GPU in #24)
1st of all, stop using nvidia-smi to see whether the GPU is active.
It will be, because nvidia-smi triggers it.
2. Check the power demand w/ powertop, then enter the BIOS/UEFI and disable the GPU there (or conversely, disable the IGP)
See what impact that has on the power demand either way.
3. A process being listed in nvidia-smi does NOT mean that the process is rendering on or using the GPU in any other way.
It means it holds the device node open and implies that the kernel module cannot be unloaded.
4. See post #17 again for the link on how to configure the GPU to fully power down when not actively used.
5. Remove the xf86-video-intel driver again, you'll have better results w/ the modesetting driver in various ways.
Also the config file prevents X11 from accessing the nvidia GPU at all and there is a chance that the kernel module moves the GPU to full power in this state (that's hard to say w/o looking at the power state of the device) - and you cannot use prime-run this way either.
In case it's not abundantly clear by now: you started this thread on a false premise and with misconfigured system.
Then you blamed the people who actually know what the fuck they're talking about for your own mistakes and shortcomings.
If you want this shit to get sorted out, review your attitude and ask back and listen to what you're told.
If not, it's not like I'd care.
