Current installer: scripts/setup/09-openbox-autostart.sh writes ~/.config/openbox/autostart for the Caspar user. It does not start casparcg-scanner or run.sh when casparcg-scanner.service / casparcg-server.service are enabled (scripts/setup/13-caspar-systemd-units.sh).
casparcg-scanner.service — After=network.target only (no X, no nodm).casparcg-server.service — runs run.sh under systemd.Sync wiring: sudo bash scripts/setup/sync-caspar-supervisor-wiring.sh
sudo systemctl restart nodm did not stop Caspar (legacy)& — The while true; do … done & block detaches from Openbox. After a nodm/X restart, those processes are not always in the same process tree as the new session; old loops can keep running (orphaned or still under a surviving user manager).autostart again, so you get another while true loop → another Caspar main process while the old one may still be alive.--type= are extra servers; killing X does not guarantee all of them exit together if multiple mains were started.Operational rule: before or after a nodm restart, assume you may need to stop Caspar explicitly once:
# See main server processes (no CEF --type= helpers)
pgrep -af 'casparcg-server-2.5 /opt/casparcg/config/casparcg.config' | grep -v -- '--type='
# Stop them (run as user that owns the processes, or use sudo if needed)
pkill -f '/usr/bin/casparcg-server-2.5 /opt/casparcg/config/casparcg.config'
# Wait until none left, then restart nodm or let autostart start a single instance.
Use pkill -f carefully: it matches the full command line; adjust if your config path differs.
Use a file lock so only one autostart loop can run, even if Openbox runs autostart multiple times.

Installer: scripts/install-phase3.sh writes this logic to ~/.config/openbox/autostart for the Caspar user (with XAUTHORITY=/home/<user>/.Xauthority). It inserts the NVIDIA line above after unclutter when /usr/local/bin/highascg-nvidia-x-apply.sh exists (Phase 2).
Notes:
flock -n — If another session already holds /tmp/caspar-openbox-autostart.lock, this autostart does nothing (no second Caspar loop)./opt/casparcg/cef-cache (find … -mindepth 1 -delete) so stale Chromium profile data does not accumulate.grep -qE ':5250\b' is a bit stricter than grep 5250.Planned restart:
pkill -f '/usr/bin/casparcg-server-2.5 /opt/casparcg/config/casparcg.config' → wait until pgrep shows none → sudo systemctl restart nodm (or reboot).
After unclean restart:
If you see more than one main casparcg-server-2.5 … casparcg.config without --type=, kill all mains as above once, then let one autostart loop respawn Caspar (or restart nodm after the kill).
Long term (current): Caspar runs as systemd units (casparcg-scanner.service, casparcg-server.service); Openbox handles X utilities and display layout only.

Problem: no lock → every new Openbox autostart could start another background loop → multiple Caspar mains.
