I am not looking to run anything with the 6800XT - rather I have a R290 that does work with qubes; I’d like to disable the 6800XT and run everything with the R290 only.
So what’s the problem? Predictably, the 6800XT is not supported as it is a new card. And my mobo loves to default to the 6800XT over the R290 for some reason - my end result is a system that can boot when the 6800XT is not in the pci slot - and can’t when it is.
I have a few options that I think may work but would love some feedback and recommendations from anybody who may have delt with this before.
My first thought is a software solution that forces Qubes to use a specific PCI slot - my theory being that this may fix the issue.I have no Idea how to do this or if It’s possible - but I figured there must be some way to chose a gpu preference in Qubes.
My second option is to install a new (non Qubes) OS on a spare drive I have and boot with both the cards, after booting I can get a list of PCI buses that are associated with the 6800XT and disable them on Qubes - hopefully fixing the problem.
A third option is installing Radeon Drivers on dom - this is obviously a bad Idea and would likely be a pain to do - compromise security and surprise surprise AMD does not create a driver for Qubes.
If anybody has suggestions or feedback I’d appreciate it.
