Hi everyone. I'm new at Proxmox and virtualization, and I'm currently stuck in making the GPU Passthrough work for my Pop OS 22.04.
It seems to be partially working, as I can see the ProxMox boot screen on TV, but after that I get a "No signal" message. I've tried the same steps on a Batocera img, and I had the same problem after boot.
I'm running ProxMox on a Dell Optiplex 3080 (Intel 10th generation), and working on a full passthrough of the igpu following the guide at: https://github.com/LongQT-sea/intel-igpu-passthru
I've checked everything on the host BIOS, and all virtualization options are set.
This is my VM configuration:
100.conf (igd.rom is the "Coffee/Comet Lake (8/9/10th gen)" file found at git repo)
/etc/defaut/grub default Linux line only has "GRUB_CMDLINE_LINUX_DEFAULT="quiet" " currently, as the guide says that setting iommu parameters are not necessary anymore. I've tried to experiment with other parameters, but with no success
My /etc/modules has nothing set as of now. I've also tried to blacklist i915.
Inside the VM, running "cat /sys/class/drm/card*-HDMI-*/status" shows "connected" for HDMI-A-3.
I'm available to show any other logs that may help in diagnosing the current problem. I've also tried old passthrough guides, but this seems to be the most recent, and also the most promising one. (As it showed at least the boot screen on the Monitor)
