Hello everyone,

I have successfully pass through the RTX2080Ti to Windows11 and Archlinux according to the community post, but there is a problem with passing through to Archlinux: the monitor will not display the screen after starting Archlinux unless the HDMI cable is unplugged and plugged back in, and after the screen is actively locked, you need to do the same to get the monitor to display the screen again. but the RTX2080Ti does not have this problem when passed through to Windows 11.

Configuration is as follows:


PVE version: 7.4.1
linux-headers: 5.15.102-1-pve


GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt pcie_acs_override=downstream pcie_acs_override=multifunction initcall_blacklist=sysfb_init"


options vfio-pci ids=10de:1e07,10de:10f7,10de:1ad6,10de:1ad7,1002:7340,1002:ab38 disable_vga=1


blacklist radeon
blacklist nouveau
blacklist nvidia
blacklist snd_hda_intel
blacklist amdgpu
