- Added signal_screen_activity() method to SignagePlayer class - Runs every 20 seconds automatically - Also triggered on any touch/user input events Multiple methods used to keep display awake: - xset s reset - Resets screensaver timer - xset dpms force on - Forces display on - xdotool - Subtle mouse movement to trigger activity This complements the system-level power management: - Works alongside display power management settings - Non-blocking and non-critical (fails gracefully) - Signals every 20 seconds + on user input - Prevents display from sleeping during playback Screen should now remain active throughout media playback.
