Hi community,
I bought two identical Lenovo ThinkCentre M910x devices to be nodes in my homelab Kubernetes cluster. I believe that I installed them exactly the same, but one has audio and video (i915) modules installed, but the other does not. I scoured the BIOS but I could not find any setting that would make a difference. These are headless systems, but I still want to use the graphics and audio.
I feel like there's something that is identifying or not identifying the video and audio devices, but I'm not sure what to do. Any help would be appreciated!
worker1 (broken)worker2 (working)on worker1 I can't even modprobe i915 to load the driver
