That's exactly your problem problem. Driver version 440.59 is not supported after PMS 1.20.2. You need at least driver version 450.51 on linux.   If you don't want to update to a beta release (thanks @MowMdown 😄 Didn't notice that he had a non-beta prebuilt!) head on over to the link below and get the "Unraid Custom nVidia builtin v6.8.3" version and copy the 8 files from the ZIP onto your flash drive.   Don't forget to make a flash backup before doing so!   You mig
