[Bug]: NVIDIA Tesla P40 Card Issues

[nphil]

Describe the Bug

Apparently there's a problem with the newer Nvidia drivers and this Pascal based workstation card. They're available pretty cheap on Ebay (100-150USD) and are excellent for AI tasks with 24GB of VRAM so I'm assuming these will be fairly popular for homelabbers.

These cards do not have any kind of display out capability. Regardless, I was able to run games just fine until recently - Steam goes haywire and Sunshine doesn't work at all (no display detected). See below screenshot for Webui:

Mikec92117 on discord advised that the last working driver version was 535.183.01, however I do not see an option to download this on unRAID with the Nvidia plugin.

Is it possible to manually select this driver through steam-headless or ideally, what could be done to fix the issue on the latest NVIDIA drivers?

PS: The latest driver works fine for compute tasks, I use Ollama, Plex transcoding etc. and everything works.

I see the same on my Nvidia tesla m60

Can see in nvidia-smi that steam is using G type and appears to be using the card, but blank windows as you see

I went back to driver 470.x via unRAID and everything works fine. Would rather figure out the issue though as I really want to keep the drivers updated.

[karl0ss]

so you had to pull the drivers back on your actual host? thats a bit of a shame...hmmm

[nphil]

yup, but i was wondering if there was a way to make the docker image pull the older version of the driver during first run - should technically able to modify the script but it's beyond my ability.

[karl0ss]

I can confirm that rolling my host back to 535.183.01 has fixed this for my Tesla M60 :)

could you try Forza Horizon 4 or RDR2 in DX12 mode? My Tesla P4 failed to launch these games in DX12 mode. Is this a common issue of Pascal card?

[karl0ss]

@aa889788 how can we play Forza? can we install the xbox for windows app or something?

The steam version, but I've just fixed it by delete the TargetHardwareProfiler.dll

Hi.
I have the same error.

Big picture mode doen't work too.
Host is arch linux and in host nvidia-smi see the processes

Could you help to understand what's wrong?

[karl0ss]

Not sure, but that is what I saw on the incompatible driver, I know for sure 535.183.01 worked, as that is what I downgraded to and it all started wroking...

things like sunshine should show as G+C for the type when its working...

[eivanov-c]

I have tried several versions of drivers
nvidia
nvidia-dkms
nvidia-470
nvidia-535.183.01
but each time I have the same error
