I just had this same issue a few days ago tho I suspect my answer won't be your answer. I was getting this on a lenovo m720q with the little add-on DP card. I plugged a cable in to get into the bios and when I restarted it was reporting that same error.... I FINALLY removed the cable on a whim and it went away. SO I did some testing with other cables and the other ports on the system. Near as I can tell my otherwise perfectly good DP to DP cable when plugged in to that add in card somehow kills the integrated GPU. |

I do have an NVS 310 card for BIOS/Proxmox, which is old enough that the drivers warn it does not address the NVS 310 so I assume(!?) it just ignores it. Now, from what I can understand is vGPU to VM is ok because Proxmox doesn't take control of the GPU (the blacklist) but since LXCs are directly related to the Proxmox kernel, it is one or the other (sharing 1 physical GPU amongst all LXCs or all VMs). But I can't get the LXCs to recognize any GPU. |

pve-manager/8.2.4/faa83925c9641325 (running kernel: 6.8.12-1-pve)
Hello, I had a Plex LXC, got a Tesla P4 to try to get hw transcoding working. I installed a wrong NVIDIA driver, uninstalled that via single user mode (Proxmox wouldn't boot), installed NVIDIA 535.161.05 following the PolloLoco instructions, verified working but when checking the Plex LXC, it refused to automatically login and after a minute Proxmox would hang. Proxmox has been stable not running the Plex container. I didn't make a back up (roast away) so wanted to make a new instance and transfer the settings over. However, the script now errors out on installation as follows:
but renderD128 does exist!?, noticed permissions so chmod 666 /dev/dri/renderD128
Run script again - this time the slash is a backslash.
nvidia-smi returns ok.
If I run my Windows VM, nvidia-smi does register a vGPU instance
mdevctl types returns ok
Clearly I'm a bit of a n00b who can get into trouble but not know how to get out of it. Appreciate any help.
