How to, restore GFX state after a passthrough

Hi,

I’m setting up some new work station based on proxmox as hypervisor, Docker for services, and some Linux distros and Windows as KVM OSes.

My first workstation contains:

  • Ryzen 3700X
  • Asus Prime B450M-A
  • 64 Go Memory
  • No named GForce 720

After having setup all VFIO passthrough stuff, I removed most of them to keep my proxmox console display at boot time.

Then I can switch On/Off one by one all my KVM one by one, and everythink working fine.

But once I started any KVM + passthrough, I can not restore my GFX to the initial state to se my console agains.

I there a way to restor my initial GFX state ?
