Well, I have over 25 years of experience with display hardware and what you describe here was never an issue.
I want to give you an example to let you know more. I have a ASRock AD2550B-ITX board[1], When another discrete video card is mounted into it mini PCIe slot or PCI slot, The IGD cannot be the primary display adapter anymore. The display is totally black. I have try to draft a few trivial patch to help fix this[2]. And I want to use the IGD as primary, does this count as an issue?
