- 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.
