Trying to force Arch not to use vfio gpu even earlier than initramfs (modprobe config)
Post Body

So I have what my msi mobo sees as the primary gpu set to be used as the passthrough gpu in the modprobe config. The issue is prior to running startx (I login in the initial cli and then run `startx` to get to my desktop) there is no gpu output from the host gpu. I can do it all by muscle memory and get to the desktop but there is no monitor output from my host card and a frozen output from the passhtrough card until startx is run and I enter the desktop. It seems Arch is trying to use a gpu that is no longer there until I run startx.

Is there some sort of xorg config I am missing to just make arch not even try to use the passthrough gpu even in the initial readout and cli right after boot but prior to startx. Or do I need to use something even earlier than where the modprobe config gets picked up to ensure I see all the initial cli output and prompts?

Or am I thinking in the wrong way and since my passthrough gpu is AMD I can actually just turn it off right as I enter desktop on my host without any issues when it is passed through on vm boot?

Just in case this is an important factor, I have an encrypted drive so right now I have to enter a passphrase before anything else. Can't see that prompt either of course.
