Is there a way to select a primary graphics other than onboard graphics? I have two different dedicated graphics cards in my machine, one GT640 and a GTX970. I am trying to set up the machine to set up Linux Mint to use the GT640 and later I will enable GPU passthrough to a KVM Windows VM for the GTX970. However currently I can only get the system to boot on the GTX970 not the other graphics card, and the graphics drivers are not working with the other graphics card anyway.
Things I have tried:
- Installing Mint then connecting to the GTX970, however it always starts trying to use the new card instantly.
- I also get a blank output on the GTX970 even with
nomodesetenabled. However ideally I don't want the Linux Mint host to touch the GTX970 anyway other than for KVM to pass it to Windows.
Does anyone have any ideas how to proceed?
