Hi,
I installed Proxmox VE on my 10100+MSI B460 machine and have only XPEnology as my virtual machine. I have been unable to change the resolution in Video Station since installation completed until now. I have made a series of modulations including setting the iommu on, SATA controller passthrough, getting QuickConnect to work and replacing the i915 driver. I couldn't also see /dev/dri listed after i915 driver replaced and I also could not make the CPU patch to work after a few tries. I feel like these problems are all somehow related to the same one. By the way, when I passed through the SATA controller and VGA to XPEnology, the iommu device descriptions are all missing except for the memory controller as in the picture.
