Did we loose driver support for the P400 with 7.2.3. Plex will not run anymore with Extra Parameters: --runtime=nvidia, but will start if I remove it. Please help as I use it for transcoding in Plex and tdarr.

Thanks

Joe

Nvidia dropped support for Pascal series GPUs, but it should work on older drivers still (580 series).

I would recommend posting in nvidia plugin thread if you continue to have issues: https://forums.unraid.net/topic/98978-plugin-nvidia-driver

I had the exact same issue and can verify that downgrading your driver fixes the issue. Make sure you disable automatic updates of NVidia driver.

Thanks - This one worked Production Branch: v580.126.09. I tried the open source ones but that did not work. How do I disable updates? Did not see that in the settings, only Driver Update Notification.

That’s a “my bad” ;-) I thought that there was an automatic updates feature, but I am not seeing one anywhere. If I happen to find one, I will post something here.

Here. If Enabled, will download the latest driver version and send a notification.

When rebooted, the new driver takes affect.

@ConnerVT thanks for the update. I was fairly certain that there was a way to automatically update the driver.

Where can I find this elusive setting?

By traveling back in time, to January 2026.

It was an option in the Nvidia Driver plugin in Settings then. ich777 has made a number of changes since , as the proper version of the driver has been complicated between all of the recent Unraid releases and requirements for the latest RTX cards and the deprecation of the Pascal chipset GPUs.

The setting likely has caused more problems than good. In the vast majority of cases, the "latest" driver won't make a difference for people. It usually addresses niche things that may affect the latest AAA video game or high end video processing. If you are having this kind of issue, the automatic notification isn't much help, for you would likely already be looking for it and usually isn't an application running in Unraid. Removing the option from Settings keeps those who update everything immediately, needed or not, from inadvertently updating then finding something broke in their server.

@ich777 - Something to note, based on the posts above:

The text in the Nvidia Driver plugin (at least in my 7.2.4) still reference the Driver Update Notification, but this is no longer available as an option to select. I only see DISABLE GPU-BASED FILTERING and UPDATE & DOWNLOAD (as well as radio buttons for selecting driver version).

setting is still there for me 🤷‍♂️

The driver update notification is only available/visible if you've selected the 'latest' driver version.

Not for me

(sorry for the funky screenshot - only way to get everything to fit.)

I see you selected the latest radio box button but did you actually click Update & Download since you are on driver version 580.x

I had to do this for my P400 a while back and set it to v580.159.03 to get Plex and the driver working again. Yesterday I tried upgrading unRaid from 7.2.3 to 7.2.5 and my server really did not behave well. After login I could only get to the main page. If I tried any other like the dashboard, setup, docker, tools, the UI just hung. I finally downgraded back to 7.2.3 and everything worked but Plex. I finally had to disable the Nvidia card from Plex to get the docker back to working. I had to wait until today to try and get the Nvidia P400 to work with Plex again as shutting down after downgrading the OS kicked of a Parity check. Oh what fun. I wish Plex would just support AMD APUs and I could get rid of the P400.
