EVGA Geforce GTX 950 GPU Passthrough Issue

[mafoster]

Hi there,

 

First time poster and new to UNRAID.

 

I have installed a EVGA Geforce GTX 950 in my server and seem to have the Windows 10 server running but no display is showing up. Here is my setup:

 

- UNRAID 6.2 RC2 (had the same issue with 6.1.9)

- SuperMicro X11SAE-M which has all virtualization enabled to my knowledge and UNRAID

- Intel i5 6400 2.7GHZ

- 16GB ECC Kingston 2133mhz RAM

- EVGA Geforce GTX 950

- 1 x 256GB SSD

- 3x 3TB, 2x4TB Array

- 6TB parity

 

Attached is my current VM configuration. I have tried with both BIOS types and both Q35-2.5 and i440fx-1.4 and both do not work.

 

I hear the GPU starting up when I launch the VM and the screen goes from the typical prompt screen to full black.

 

Any help would be much appreciated. I am wondering if its the card that isn't compatible or if I am doing anything wrong.

Set the onboard graphics to be default. That way unraid uses that GPU for the console and you are free to use the nvidia card.

Thanks saarg. Do you mean set the onboard graphics to default on the BIOS settings of the motherboard or as the primary GPU and NVIDIA as secondary in the VM settings?

In the BIOS 

[mafoster]

Thanks Saarg. You were right, that worked. I had to not only turn on the Intel Graphics but also set it to default vs 'auto' which seemed to make the PCIe card be the default.

 

I now have a who new set of problems but that's for another thread.

 

solved thanks.
