Picking a new "Screen Blank Timeout" in SpoolBuddy Settings → Display
didn't change actual blanking behaviour: whatever value was active when
the kiosk last booted continued to fire. A user who started with the
10m preset and switched to 1m or "Off" still saw the screen blank at 10m.
Cause: blanking is driven by swayidle, started once by spoolbuddy-idle.sh
at labwc autostart with the timeout passed as a command-line argument.
The script fetched blank_timeout from the backend exactly once at startup
and swayidle has no runtime control surface for changing its timeout.
The daemon's display.set_blank_timeout() updated an in-memory variable
that was never reached by swayidle, so UI changes were silently discarded
until the next kiosk restart.
Fix: extend the wake FIFO protocol with a "reload-timeout N" message.
The daemon writes it whenever set_blank_timeout() sees a value that
differs from the current one (the very first call is suppressed because
the watchdog already fetched the same value at its own startup —
signalling there would just thrash swayidle on every cold boot). The
script's FIFO loop is restructured around start_swayidle / stop_swayidle
helpers and a case statement: wake → wlopm --on + arm a re-blank at the
current timeout; reload-timeout N → kill running swayidle, set TIMEOUT=N,
restart swayidle, wlopm --on so the user sees the change took effect
even if the screen was already blanked. The script de-dupes too — a
reload-timeout whose N matches the current value is a no-op. Going from
any positive timeout to 0 ("Off") stops swayidle and doesn't restart
it; going from 0 to a positive value starts a fresh swayidle. Both work
without a kiosk restart.
The script's main loop opens the FIFO read+write (exec 3<>"$WAKE_FIFO")
so bash read never sees EOF when the daemon momentarily disconnects
between writes. A cleanup trap on TERM/INT/HUP stops swayidle, removes
the FIFO, and exits cleanly.
