unraid gpu passthrough on laptop

Hello,
I need help with the configuration of the virtual machine.

What I want to achieve:

Run a virtual machine on a laptop so that it will use a graphics card including a built-in monitor.

The laptop is Dell Inspiron  7566.

Problem:
When the virtual machine starts, the main screen goes blank and nothing is happening on screen.

 

The laptop has two built-in graphics cards. The screen goes out when I add an Intel integrated card to the virtual machine. I guess it's happening because currently unraid is using it to display the console. How can this be achieved? I do not know how to release this card so that VM can use both cards together with the built-in screen.

Yeah, unfortunately laptop GPU passthrough mainly doesn't work.  @jonp can chime in, but we have not had much luck with this.  Theory is, since laptops are generally not expandable like desktops, lots of corners are cut in the architecture of mobile devices.

I have had success with passing the primary GPU and a secondary one in a desktop and then switching using OS settings. Install your OS using VNC then pass through both GPUs to the same VM and see what happens. You may need to attach an external display to a video output port for it to work.

Meaning the laptop screen itself won't display anything?

Whatever is using the integrated graphics will probably show up on the built-in display. An external display may be required to see the output of the dedicated GPU.
