GPU Passthrough GTX1050, proxmox 8.0.3

[User2023]

Hello,

I try to forward my Gtx-1050 on my "Acer nitro 5 AN515-52-78CU" to a VM(ubuntu).
Version: Proxmox 8.0.3. I will connect to the VM only via SSH or VNC. I will not use an external monitor....

Error(at the bottom of the post):
nvidia smi failed to communicate with driver....

Host settings:

Сhecking the compatibility of my video adapter.

Inside VM(ubuntu server):
- latest drivers are installed
- device is visible in the system

Got error:
nvidia smi failed to communicate with driver....




PS:
I will provide any command output as quickly as possible.
Sorry for my bad english.
