Hello everyone, I have some trouble getting PCIe passthrough to work properly on my Proxmox VE 6.2-4. The curent setup I have contains 2 GPUs: - GTX 1070 mini in prmary (top) slot - GTX 770 in secondary slot Passing through PCIe devices works. I have confirmed this by passing through the GTX 770 to a Windows 10 VM which works as expected. My issue is that, when trying to pass through the primary slot GPU, the GTX 1070 in this case, I get no output and the device is not recognized by the VM in the devices manager. Drivers are blacklisted and both cards are configured to use vfio. My current guess is that, since proxmox uses the primary slot for local output prior to the VM being launched, proxmox essentially blocks the device from being able to be passed through. Any ideas on how to pass through the primary slotted GPU would be appreciated as I plan to upgrade to an nVidia 3000 Series card soon and would like to take advantage of PCIe 4.0, which is only available on the primary slot of my Mainborad. Kind regards, PacDDrake

Hello everyone, some quick context for my Issue that will hopefully clear up any possible misunderstandings: For my birthday (which happens to be today), I decided to upgrade my gaming/development machine with some new hardware. At the same time I decided to try and switch to Linux as my main operating system since it just feels nicer compared to Windows 10 for me. Also, Proton has made gaming on Linux a much more pleasing experience by now since almost all of my games now run with great performance. Still, for the few games I have that will not run with Proton or Wine I decided to use Windows and just run it in a VM so I don't need to switch OSs every time I decide to have a quick match. Long story short, my machine now has 2 NVIDIA GPUs: GTX 770 and GTX 1070 Mini running on a new Gigabyte X570 Aorus Elite with a Ryzen 7 3700X. The GTX 1070 is intended for any heavy lifting purposes, such as gaming, and thus has my 2 big 1440p monitors attached to it, while the GTX 770 is merely intended for output of the host system in case I run any VMs with GPU-passthrough, which is a can of worms I decided to open at a later date. My current Issue is that, even though all hardware, both GPUs and all 3 on my monitors are confirmed working, but any display attached to the secondary GTX 770 GPU shows no output and is not shown as a possible output device in the display manager: However, both the secondary GPU as well as the attached 1080p horizontal monitor are recognized by nvidia-settings as existing and theoretically working: (GPU 1, HDMI-0) I have googled a lot this past day, but most issues I came across are with hybrid mode for GPU and CPU-onboard graphics. If anyone has a solution for my Issue to get the third monitor on my secondary GPU working, it'd be the best birthday gift I could ask for. Sincerely, PacDDrake Quick Update: I have managed to enable the tertiary monitor by creating a new X Screen for it in the nvidia-settings: It now shows output. has the correct resolution and orientation and I can now move my mouse into it. However, I only get a black screen (no wallpaper like on the others), the cursor immediately changes to a black X and I cannot drag any applications into the screen. Any help on getting application output, even if they then cannot be dragged between the different X Servers would be much appreciated.
