Hi guys,


I've read that when the GPU is stubbed (pci-stub.ids) it equals to being blacklisted and not initialized, falling off the bus ?


How does that translate into power consumption ?


From time to time I wanted to test out the iGPU (HD4600) without having to remove the dedicated GPU (GTX 760) or

when having it integrated without too much overhead of power consumption.

This is in preparation for long-term usage of KVM and Windows, running Windows-only games on the emulated machine with 95-99% of native performance


Thanks in advance for the answer

I don't think it will affect power much, as in, it'll use as much power as it does when you have no driver loaded. You'll have to depend on a power meter to know for sure; but removing it will use lower power, guaranteed.

If you don't have a power meter, you can see if the GPU heatsink gets warm (you may need to disable the fan). Chances are, it will still get warm and you are wasting power.
