Edit: Finally came across the thread concerning Battlemage support, link below. I got the build and my B580 is now working.
Server Version#: 1.42.2.10156
Player Version#: any client
Linux version: Ubuntu 24.04.3 LTS
Kernel version: 6.14.0-37-generic
My PMM Transcoder settings can see both the iGPU and GPU, but neither of them are actually used for hardware transcoding. I have a docker-based app that is using the GPU for hardware transcode, so I know it works. Any help on troubleshooting this?
iGPU and GPU details:
