      Hello,
      I build a Magic Mirror with my Raspberry PI. Everything works fine.

      But sometimes (every 1-2 days), the Raspberry hangs after he turned on or off the monitor.

      At first i used this commands:
      sudo vcgencmd display_power 1
      sudo vcgencmd display_power 0

      => Result: Sometimes the Monitor freezed. (even if i killed the magic mirror application via ssh, the monitor was freezed).
      Really really bad was the fact, that i can’t reboot the raspberry via ssh. when i try “sudo reboot”, the raspberry looses the wifi connection, but doesn’t reboot. => not usable any longer.

      Then i tried this commands:
      tvservice --preferred
      tvservice --off

      But here, sometimes, the tvservice hangs after 1-2 days. i can’t control the monitor any longer.
      “tvservice --status” hangs also, and doesn’t get more informations.

      With the tvservice commands i can reboot my system, but reboot every day, is not really cool.

      Does someone have an idea? i already switched the power supply, but nothing changed.
      and i’m sure, that it happens always 2-3 seconds after the monitor turning on or off.

      Kind Regards
      Stefan
