ahhchuu Posted February 26, 2016 Share Posted February 26, 2016 I just replaced my AMD HD 7870 with a Nvidia GTX 970. When I try to boot up my Windows 10 VM, I don't get any display (screen stays black). I can boot up with VNC so I thought I should try installing the drivers for the new card. Nvidia doesn't let me do that without the card present, which it isn't because I can only boot in VNC. I guess there is a setting that needs to change due to the switch from AMD to Nvidia but I can't figure out what it is. Any help is appreciated.

sweigh Posted February 26, 2016 Share Posted February 26, 2016 Sounds similar to an issue I experienced last year with AMD vs Nvidia cards. I never ended up resolving the issue, but my fix was to use an AMD card to boot the VM. Something about Nvidia not liking passthrough when it's initially used as the boot/console device. There was a mention that if both the AMD and Nvidia cards were installed, and the AMD card was used as the boot/console device, then the Nvidia card might get passed through. If you can fit both cards in the system, I'd give that a try. Quote Link to comment
ahhchuu Posted February 26, 2016 Author Share Posted February 26, 2016 but my fix was to use an AMD card to boot the VM As in, use the AMD card via passthrough for your VM instead of the new Nvidia card? That wouldn't solve my problem as I will not be keeping the AMD card. I attached both cards to see if booting unraid with the AMD card would magically allow me to use the Nvidia one as passthrough for my VM but that doesn't work. Quote Link to comment

Is the Nvidia card the only Graphic card in the server? No integrated graphics? If so you will not be able to pass through the nvidia card as it's not possible now. Jonp hinted they were close to a solution, but that is all we know. AMD cards doesn't have this problem when being the only card. 1 Quote Link to comment
ahhchuu Posted February 26, 2016 Author Share Posted February 26, 2016 No, there is no integrated GPU on my server. Hopefully they come up with a solution soon. Thanks for the help, guys. Quote Link to comment
henkall Posted February 27, 2016 Share Posted February 27, 2016 Try not to pass through your onboard sound and use the NVidia graphics card sound instead. Quote Link to comment
snazz Posted February 27, 2016 Share Posted February 27, 2016 Try not to pass through your onboard sound and use the NVidia graphics card sound instead. In doing so, you won't get sound out of your speakers if they are plugged into the speaker out jack, correct? Quote Link to comment
henkall Posted February 28, 2016 Share Posted February 28, 2016 That is correct. But if that worked with the graphics card problem then he would probably just have to add a secondary audio device witch could bee the onboard soundcard. Quote Link to comment
frankgore77 Posted February 28, 2016 Share Posted February 28, 2016 im having this same problem right now and i cant figure it out it just goes black when i try to load my vm. Also when i use vnc it says there are no drives found its really a problem and im clueless Quote Link to comment
