I’m in the same boat.

As I’ve worked my way through this thread (thank you to all who have contributed!) I finally got to the point where my 1080 was recognized:

and the GPU appeared as a viable contender in the PleX App settings:

However, when I hit “Update” I was greeted with:

More info:

Version info for PleX:
App: v1.42.1.10060-4e8b05daf
Version: v1.2.10

TrueNAS Scale: Version: 25.04.2.1

Where next?

Thanks for any info

This absolutely worked! Thank you for that!

I love your signature; I too try to have approximate knowledge of a great many things; sometimes the approximation is better or worse

I am having a similar issue. Nvidia drivers with a GTX 1080 worked just fine on 24.10 and 25.04, upgraded to 25.10 and it’s not working now. Getting the

``root@truenas[~]# nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running``

Not sure if this is an issue like others have said with legacy drivers not being use, but curious if this is a 25.10 bug

25.10 updated the Nvidia driver and anything older then a 1660 is no longer supported by the newer driver

NVIDIA Kernel Module Change in TrueNAS 25.10 - What This Means for You

With the upcoming release of the TrueNAS 25.10 “Goldeye” beta, there have been some changes made to the NVIDIA drivers and supporting modules that are compiled and shipped with TrueNAS. TrueNAS 25.10 now uses the NVIDIA open GPU kernel modules with the 570.172.08 driver. This enables TrueNAS to make use of NVIDIA Blackwell GPUs - the RTX 50-series and RTX PRO Blackwell cards - which many users have requested support for.
