Mike 2026-08-20, revising the 2026-07-31 iGPU-only call with the 2026-08-04 finding that this UHD 630 has no HEVC encode entrypoint. runtime: nvidia + NVIDIA_VISIBLE_DEVICES/CAPABILITIES on the plex service; /dev/dri stays. Also brings the compose current with the live opt-in watchtower config, and 50-plex.sh now sources WATCHTOWER_NOTIFICATION_URL (carries the publish token) from stacks.env, soft-gates on nvidia-smi, and adds the NVENC line to the walk-away checks.

# 50-plex — start Plex against the MIGRATED data directory.

# Usage: sudo /srv/mediabox-bootstrap/scripts/50-plex.sh

|
# NO CLAIM TOKEN. This is deliberate and important.
|
|
#
|
|
# The migration carries MachineIdentifier, ProcessedMachineIdentifier and the
|
|
# online token across in Preferences.xml, so this server IS the existing
|
|
# server: already claimed, shared users still invited, clients still pointed
|
|
# at it. Claiming would mint a NEW identity and throw all of that away — the
|
|
# exact thing the migration exists to preserve.
|
|
#
|
|
# If you find yourself reaching for https://plex.tv/claim, stop. Something has
|
|
# gone wrong with the Preferences.xml step in migration/README.md § M3.

* Continue Watching should be populated — that is the whole point.

|
* A remote client that already had this server should still see it

without re-adding.

* Force a transcode, then: sudo intel_gpu_top

Video / VideoEnhance rows should be busy.
|

* Force an HEVC-out transcode, then: nvidia-smi
|
|
Plex Transcoder should hold an ENC session on the 1070.
