Installing Nvidia drivers on Proxmox host.

[Jackster]

I need the Nvidia drivers installed on my Proxmox host as I am having to run Plex on the host rather than in a VM.
I have a p400 and am running the latest Proxmox.

root@proxmox:~# lspci | grep -i nvidia
02:00.0 VGA compatible controller: NVIDIA Corporation GP107GL [Quadro P400] (rev a1)
02:00.1 Audio device: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1)


root@proxmox:~# nvidia-detect
Detected NVIDIA GPUs:
02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107GL [Quadro P400] [10de:1cb3] (rev a1)

Checking card: NVIDIA Corporation GP107GL [Quadro P400] (rev a1)
Your card is supported by the default drivers and legacy driver series 390.
It is recommended to install the
nvidia-driver
package.


I run apt install nvidia-driver and it downloads and installs stuff.
Restarted and tried nvidia-smi but it fails.

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

As you can see the driver is not initializing with the GPU.

Any ideas?

Only ever done ATI on uBuntu so this is quite new to me.
Thanks

PVE blacklists the nvidia driver by default, as it is known to cause some issues. Check the file /etc/modprobe.d/pve-blacklist.conf for more, or remove it to disable the blacklisting and allow the driver to be loaded.

To make sure the package has been installed correctly, you can also attempty to manually load the driver with modprobe nvidia.

Should that blacklisting not be reverted?
The related bug is 5 years old and seemingly closed/fixed (https://bugzilla.proxmox.com/show_bug.cgi?id=701).

AFAIU the bug was closed *because* we added the blacklist, not because the underlying issue was fixed. Could maybe be removed now, but tbh it's very rarely necessary to load the NVIDIA module anyway and you might as well just remove the config manually then. Removing it now would require a lot of testing to make sure it runs stable, and for 99% of users nouveau will do the job just fine...

In any case, if it really bothers you, you're welcome to open an issue on our bugtracker.

Not really bothered, am using the Nvidia run-file installation now, works fine with Proxmox. Couldn't get the Nvidia Debian packages to work on Proxmox personally.

Can you elaborate on how you got this working? I've been banging my head against the wall trying to get the nvidia drivers to load through the Debian packages as well with no success.

Well, same for me. So I downloaded the drivers from Nvidia site, the run file. You can remove the Debian packages before, or the installer will tell you to do so I believe.
