charris

Looking for some suggestions for troubleshooting from here as I'm almost out of ideas. -HP Desktop (h8-1409) (pegatron corporation 2ad5 version 1.03) -Running latest firmware (granted, it's five years old) -Quicksync CPU (https://ark.intel.com/content/www/us/en/ark/products/65719/intel-core-i7-3770-processor-8m-cache-up-to-3-90-ghz.html) -Onboard video (with DVI-A and DVI-D ports, no HDMI) -AMD card (in BIOS, I've enabled onboard video and set the Intel VGA controller to "Primary VGA device" - this seems to be as close to enabling iGPU that other threads mention in similar situations) -6.7.2 (also tried 6.6.7 and 6.8.0RC5 - see notes below) I manually do this (details below): modprobe i915 chown -R nobody:users /dev/dri chmod -R 777 /dev/dri The Plex docker ( https://forums.unraid.net/topic/40463-support-linuxserverio-plex-media-server/ ) works fine until I try transcode something, then the server hangs instantly. In 6.8.0RC*, the behaviour changes - as soon as I type modprobe i915 it hangs instantly - no need to start Plex: https://forums.unraid.net/bug-reports/prereleases/modprobe-i915-causes-immediate-server-hang-r686/ This is what makes me think it's not the Plex docker itself, but rather something with my hardware or configuration. Things I've tried: 1. Switching to UEFI 2. adding i915.alpha_support=1 to syslinux.cfg 3. adding intel_iommu=off to syslinux.cfg 4. As an aside, adding the following to "extra parameters" (because I've seen all three variations in various places): --device=/dev/dri --device /dev/dri:/dev/dri --device=/dev/dri:/dev/dri I've attached server diagnostics. I think I've followed relevant threads on this issue but no luck yet so just looking for another set of eyes if anyone has any ideas. Thanks for reading!
