I recall a BIOS option to disable Optimus in a dell laptop I had used. Have you tried turning this off and then assigning the GPU?
When I disabled it in the BIOS, the built in display seemed to run off the integrated card and the external ports ran off the GPU iirc.On Thu, Mar 31, 2016 at 2:10 PM, Tom A <agentlecomputer gmail com> wrote:_______________________________________________---------- Forwarded message ----------

To: Alex Williamson <alex l williamson gmail com>I see... well that sucks. I wonder if anyone has brought this up to the Nvidia developer? Maybe I can bring this up in the dev forums and see what they have to say about the issue. But it does seem like I have hit a dead end.P.S. Just to be clear, you are saying that open source firmware like OVMF do not have the features that the proprietary BIOS on my laptop have for managing Optimus technology, right?On Thu, Mar 31, 2016 at 10:35 AM, Alex Williamson <alex l williamson gmail com> wrote:Nobody has successfully assigned an Optimus GPU to a guest yet, afaik. These hybrid laptops are not simply an integrated and discrete GPU in the same case with the ability to switch between them, there are proprietary BIOS requirements that we cannot replicate in open source firmware to make that happen and it's not clear if there's any way to make the GPU work independently of those features. If you can make it work, document what you've done, but don't expect that it should just work. Good luck.
