Description=monitor-lets-go — automatic monitor layout daemon
Documentation=https://github.com/mat/monitor-lets-go

# Ensure the daemon starts after the graphical session is ready and
# stops when the session ends.
PartOf=graphical-session.target
After=graphical-session.target
Requires=graphical-session.target

[Service]
# Type=notify with WatchdogSec: the daemon periodically reports health.
# If it hangs, systemd kills and restarts it — critical for recovering
# from a black-screen state (restart re-evaluates monitors and applies
# the correct layout).
Type=notify
WatchdogSec=30

ExecStart=%h/.local/bin/monitor-lets-go -config %h/.config/monitor-lets-go/config.yaml

# Fast restart on failure: if the daemon crashes during docked mode,
# it will be restarted within 1 second and immediately apply the
# correct layout for the current hardware state.
Restart=on-failure
RestartSec=1

# Allow up to 5 seconds for graceful shutdown (portable layout restore).
KillSignal=SIGTERM
