Server Version#: 1.43.2.10623 Player Version#: Plex Web 4.159 Proxmox 9.1.9 OS: Ubuntu 24.04LTS LXC privileged CPU: i9-10900K (Comet Lake) This Plex server had hardware transcoding working for the last few years. It stopped working a few weeks after updating to Proxmox 9.1.9. I can see the iGPU on the Plex server and I did chmod 777 /dev/dri/card0 and /dev/dri/renderD128 (just to troubleshoot) which did not seem to fix it. Doesn’t work with HDR tone mapping enabled or disabled. I see this in the logs but video doesn’t play May 14, 2026 23:56:37.293 [131578153851704] INFO - [Req#810/Transcode] Preparing driver imd for GPU Intel CometLake-S GT2 [UHD Graphics 630] EDIT: Posting in case anyone runs into this issue. Looks like Linux 7.0.0-3-pve has an issue with intel and nvidia gpus. Had to rollback to Linux 6.17.13-6-pve to get this resolved. ---
