   I have an ASRock B450M Steel Legend and a Ryzen 5 3400G, with an RTX 3060. After installing the card, my iGPU was disabled. How do I re-enable it so that I can use both gpus in my operating system?

	Ok so the relevant option seems to be 'IGFX Multimonitor', but that isn't available in my BIOS. I found a reddit post, and this is what I did: I set my igpu as the primary video adapter. After that my monitor got no signal, so I unplugged the HDMI cable from my GPU and inserted it into my motherboard. Even then my mobo wouldn't output a signal, I don't know what went wrong then, but the 2nd or third time, it did POST. After that I've had no issues (so far) and windows detects both the nvidia card and a microsoft basic display adapter (I think I need to install drivers for the igpu). On linux inxi -G detects both GPUs.
