January 12, 20215 yr I just finished assembling my unRAID server and hit a snag when installing Plex. I was following a guide on YT and I noticed my server has no /dev/dri for hardware encoding. I start down the rabbit hole and the GPU does show up in the IOMMU list and outputs a signal to a monitor, but doesn't seem to be recognized by unRAID other wise. symptoms: I installed the 'GPU Statistics' plugin and it shows no data. Clicking on the settings button, I get the error 'Error 300: Vendor utility not found.' Plex will start no issues without any hardware encoding set up. When I try to set it up by adding another device to the Plex docker, as in the guide, named /dev/dri with the value also set to /dev/dri the docker will not start and checking the logs I get the text below.

Looking into other threads I found some similar issues dealing with intel chips. I tried some of those fixes and found no results, presumably because they were for intel. unRAID version 6.8.3 GPU 1070 CPU Ryzen 3600 Board ASUSTek Tuf B450M-Plus Gaming
