You could try blacklisting the Intel one. You would need to check which
module it is, but probably "i915". Or check in your BIOS, you might be
able to set the other card as primary.
Blacklisting the i915 didn't work, so I changed the BIOS settings and
that did it.
Unfortunately, although some games work well (e.g. Witcher 3), others
don't (Assassin's Creed Odyssey - lots of stuttering), so I'll probably
back off from this for the moment, though a more high-end GPU might
have better results (mine's a lowly GTX-1050). It's interesting that
the GPU passthrough with QEMU/KVM works so well in comparison, given
that it's a whole virtual machine.
Thanks for your help.
