61:00.1 Audio device [0403]: NVIDIA Corporation GB206 High Definition Audio Controller [10de:22eb] (rev a1)

This basically means that something is wrong with some BIOS setting.

Please check if you are on the latest Firmware version from your BIOS, then make sure that Resizable BAR Support & Above 4G Decoding is Enabled in your BIOS.

What you can also try is to swap the cards physically in your Server since this sometimes also helps, if that also doesn't help try for troubleshooting to lower the PCIe Generation for the slot where you 50 Series card is in to Generation 3.0

Thank you - resolved

(The GT730 is just for server to boot as its a workstation MB without IGPU).

For those searching the forum, as reference for RTX5060 TI;

• Unraid had loaded nouveau driver (unsure of cause as not part of Unraid). Execute theses commands from an Unraid Terminal and reboot afterwards:

Disabled nouveau driver

mkdir -p /boot/config/modprobe.d

echo "blacklist nouveau" > /boot/config/modprobe.d/nouveau.conf

• ASUS Workstation/ Threadipper AMI BIOS settings to allow Above 4G encoding

  Advanced settings -> PCI Subsystem settings -> Re-size BAR Support - switch to Enabled

  • Need to have CSM disabled (Go to BOOT section and set CSM (Compatibility Support Module) to disabled

  • This requires UNRAID to be in UEFI mode (On WebUI click Flash device and enable "Permit UEFI boot mode" checkbox)

You have a different issue:

GTX10 series seems now to be legacy and you have to use driver version 580.x for your cards, 590.x versions will only work for GTX16/RTX20 series and up.

Hi,

Then please do not remove support for 580x drivers- I'm stuck with an GTX 1080Ti

I won't remove them since these are now the legacy drivers, but please do keep in mind that you possibly need a new card in the coming years, just saying, because one day Nvidia will drop support for these cards and then the driver won't compile against newer Kernels.

I even uninstalled/reinstalled this plugin...this issue doesn't happen on any other menu option.

Sorry, I don't see anything obvious from your syslog, everything seems to be working just fine.

The plugin page issues nvidia-smi once to get the necessary data about your GPU(s) on the plugin page, do you maybe have other Dashboard pages from Unraid open, I assume you have GPUStatistics installed correct? If yes, please set a reasonable refresh rate from 2000 or even better 5000ms in the GPUStatistics plugin <- however this is just an assumption what could cause this.

Ok thanks for confirming the log looks good. It's odd because it didn't coincide with an Unraid update or anything...just one day the issue began...for months I've had the same setup and I could access the driver package page no problem...

UPDATE: I just tried accessing the page from my phone and what's interesting is that this issue doesn't seem to impact the server at all...what I mean is when I try to access the page on my phone, it hangs on my phone but on my desktop everything is running smoothly (can change menus, CPU/GPU utilization is low, etc)...very strange...

For anyone running into issues with the NVIDIA Driver plugin on Unraid — especially if you’ve got a 5060 Ti — make sure you’re using the open-source drivers, as recommended.

If you’re still getting the “can’t communicate with driver” error, here’s what finally fixed it for me after many hours of troubleshooting:

1. Ensure your motherboard BIOS is on the latest version

2. In BIOS, switch to UEFI-only mode (no Legacy or hybrid).

3. Confirm your Unraid drive boot is using UEFI by having the folder called “EFI” NOT “EFI-“

4. My boot flash was originally made back in 2018, and that turned out to be part of the issue since the UEFI boot files were old and incompatible. I ended up downloading the latest Unraid install and replacing the EFI folder on my flash drive with the new one (so that I didn’t need to use another drive and I’m lazy).

After those steps, everything worked perfectly. It’s a pretty niche problem, but hopefully this saves someone else a few hours of frustration.

Should everyone using an Nvidia card be using the open source driver or just when having issues? And what kind of issues were you experiencing?

No, only RTX20 (including GTX16) series and up support the open source driver.
All cards below must use one of the other drivers.

It's a bit more complicated.

With 30 series you can use both, only 50 series requires Open Source.

Thank you so much. That was able to resolve the issue I was having.

nvidia driver version 590.xx causes "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."

hardware: Nvidia GPU P2000.

tried to rollback to version 580.xx by selecting version in the nvidia plugin. System says 590.xx already downloaded. I guess asking how do I roll back to a previous driver version (580.xx seemed to work)?

Can you please post a screenshot from which message you are presented with?
I really can't imagine that other folks can downgrade the driver and it won't work on your system. Select a static 580.x driver version and click Update & Download <- this will take some time.

Your Pascal card is now basically deprecated by Nvidia and it's now in the legacy branch which means you have to stay on the driver versions 580, so just a heads up that you have to buy a new card in the next few years.

attached is screenshot per your request. I also tried to remove the plugin, after reboot it reappears.

Hey guys..........just trying to get my tesla p40 to work on unraid ..... latest unraid (7.2.3) and I understand (atleast from what I have found - apologies if I am incorrect) that 535.183.01 is the only driver that works.

I get "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 well.

As noted in the above post with the listings of drivers, 535xxxxx is not there.....

any suggestions?

(i have the 750W x2) as well

From the plugin page I select v580 (open source) as its listed as an available driver and I get the attached. Remember I uninstalled the plugin, reboot and the plugin reappears after reboot.

Hi,

Is it possible to upgrade open kernel driver for unraid 6.12.15 ?

I have a 5000 series GPU I want to use, and Unraid 7.2 doesn't startup my dockers correctly (rc.docker: Docker daemon... Failed. but they startup OK manually, etc /etc/rc.d/rc.docker start) , lacks nerdtools and everything else I want to use, as a result I backed out to 6.12.15 until 7.x is improved.

Presently on 6.12.15 I have only the option of Open Source Driver: v565.57.01 .

In Unraid 7.2.3, "NVIDIA UNIX Open Kernel Mode Setting Driver for x86_64 580.95.05 " worked.

I see driver 580.95 supports kernel 6.1. Is it possible I can modify the nvidia plugin startup script to install a newer packaged driver other than the old nvos-565.57.01-6.1.126-Unraid-1.txz ?

Or run the NVIDIA-Linux-x86_64-580.95.05.run

thanks,

Jonathan

Please post your Diagnostics.

Have you yet tried to select for example v580.126.09 from the list here:

and then clicking Update & Download? Since this is what I already said above, if you just leave it at v590.48.01 and you've click Update & Download it will just verify the Checksum.

However if the plugin reappears something is wrong on your system since this should not happen and possibly the plugin cannot be uninstalled for some reason.

Sorry, but this plugin doesn't support vGPU's and you even don't have the plugin installed from what I can see:

However you can compile your own driver package and have to make sure that it's correctly load at boot, please see this container:
https://github.com/ich777/unraid_kernel
and the build script for the Nvidia Drivers is here:
https://github.com/unraid/unraid-nvidia-driver/tree/master/source

Please do note that in my opinion it's not worth to go through all the effort and just upgrade to 7.2.3, I haven't heard anything bad about 7.2.3, I would strongly recommend to upgrade.
