- Created .keep-screen-alive.sh wrapper script with multiple methods: * systemd-inhibit (primary - prevents OS-level sleep/suspend) * xset commands (prevents X11 screensaver) * Mouse movement (prevents idle timeout) - Added screen-keepalive.service systemd unit: * Runs xset s reset every 30 seconds * Auto-restarts on failure * Integrated with graphical session - Multiple layers of screen protection: * HDMI blanking disabled * CPU power saving disabled * System sleep/suspend disabled * X11 screensaver disabled * DPMS (Display Power Management) disabled * Display forced on periodically Screen will now remain active while player is running, preventing lockups or blank screens during playback.
