April 12, 20215 yr I have seen many people asking this question but I have yet to find a solution for my particular setup. I am wishing to pass my primary GPU, a P2000, to my WIn10 VM. I do not have an iGPU on the motherboard. I placed a seperate dedicated GPU into the primary pci slot and the P2000 into the secondary. I was able to dump the P2000 rom. I then replaced my P2000 into the system as the only/primary GPU. I edited my VM setup for the P2000 yet I am met with a stagnet gray/black screen on Splashtop Desktop viewer 9attached photo). I cannot seem to find anything that will get me any further. Please help!

April 12, 20215 yr Are you booting the server by legacy boot or uefi? You can check this on the maintab/flash at the bottom of the page. I find that booting legacy works better for me with passthrough so if you are not booting legacy you could try. Also you can try adding this to your syslinux config file video=efifb:off so for example label Unraid OS menu default kernel /bzimage append initrd=/bzroot with added would be label Unraid OS menu default kernel /bzimage append video=efifb:off initrd=/bzroot Hope this may help

I went ahead and added that line to my Unraid OS section. Unfortunately still same result. Does it make a difference that I have previously setup Plex with GPU passthrough and installed the Nvidia Drivers?
April 12, 20215 yr Um I am not sure if the nvidia drivers would be a problem with the 1 gpu. Maybe as they are loaded before the gpu is passed through it maybe could. Try uninstalling the drivers and try again. if still doesnt work then goto tools/systemdevices and stub the P2000 both graphics and its sound parts and reboot You mention splashtop showing a black screen. Can you test with a monitor directly connected to the gpu whilst testing?

Can you test with a monitor directly connected to the gpu whilst testing? Wow! This forum is awesome. Such quick replies and willingness to help! Well, I am not sure which step got it to work but thanks to you both! When I initially tried the steps suggested by TAFKA Gridrunner it did not work. I had not yet restarted at that point though. So I restarted and in the meantime noticed SI1's response. I had not even thought to test it out using a real monitor! I made no further changes expect hooking it up to the monitor. And it all booted up just fine! Thanks to you both! I had been working on this one thing for almost 2 whole days to this point. EDIT: A little premature celebration but hope you guys can help here. SO my goal is to have this computer in a separate room without a monitor. I have noticed that all I have to do is plug in the P2000 to a monitor and it works on both a real monitor and Splashtop. My dilemma then is how do I get this to work without having a monitor connected to it at all times? Edited April 12, 20215 yr by Johnny Utah
April 12, 20215 yr Glad you have it working. By the way SI1 and TAFKA gridrunner is the same person .My orginal username on the formums many years ago was gridrunner hence the tag TAFKA Gridrunner !! 😉 If you want to be able to have no monitor plugged in you will need an hdmi or display port dummy like here https://amzn.to/3mH5e3I
April 12, 20215 yr Author Ha! Yeah I realize you are the same guy now. I was reading too quickly and overlooked that. Thanks again for the help! I will be ordering a dummy plug.
