February 7, 20224 yr I successfully upgraded my video card (from Nvidia 970 to 3060 TI) and mostly everything is working (Unraid, Windows VM, Plex). However, I have setup a Ubuntu VM and having a little problem. When using the 3060 TI as the video card, all works well until I install the Nvidia drivers in Ubuntu. Without the Nvidia driver it displays in 4k, etc. I tried to install the Nvidia driver, and upon reboot I just get a black screen. Note that the Nvidia 3060 TI is a secondary card. When I set the VM back to VNC for the video card, the VM will only boot into installation mode, trying to re-install Ubuntu. Any suggestions? Edited February 11, 20224 yr by ptmurphy
February 10, 20224 yr It doesn't seem an issue related to passthrough, but to nvidia drivers and ubuntu. I would suggest to write directly to the ubuntu forum, having a manjaro build I often read about black screens issues with nvidia after updates. Remember that when you passthrough the gpu there's little or no difference at all compared to bare metal, so issues related to bare metal installations can be replicated in or vms. The only thing I would check is the setting of the gpu in the vm, make sure you passthrough all the components of the gpu in a multifunction device. Edited February 10, 20224 yr by ghost82
February 11, 20224 yr Author Thanks for the reply. I did finally get it to work. Seems like Unraid didn't like trying to switch from VNC to passing through the video after initially creating the VM. I started from scratch, passed through the video card, and just for safety sake passed through the VBIOS was well.
