OK you were right, i changed it but there is no change in the behaviour. The Monitor remains without video signal just with backlight if i switch the light in the room on. Do you have any hint for me what i can check?

@bobbythemoh Did you reboot after correcting the option?

[idoodler]

@bobbythemoh You may also try to uninstall xscreensaver

There is indeed some very weird issue going on with the HDMI and screen saver/blanking as I reported here. It started after I updated my kernel (from 4.9.80) & what else came with it. Out of curiosity, what is your OS version?

[bobbythemoh]

@idoodler yes i did reboot. and i just uninstalled xscreensaver (after that i did a reboot) but no change in the behaviour.

@E3V3A I used “uname -a”:
Linux MagicMirror 4.14.34-v7+ #1110 SMP Mon Apr 16 15:18:51 BST 2018 armv7l GNU/Linux

Bobby do you have a solution for this? I’m having the exact same problem since updating my pi to the latest version of rasbian

[bobbythemoh]

no, solution yet unforunately.

I just experienced a similar issue, but It appears not to be caused by MMM-Loxone. I am Invastigating it…

@idoodler
I found this passage in your code:

    _togglePresence: function _togglePresence(isPresent) {
        if (isPresent) {
            // Check if hdmi output is already on
            exec("/opt/vc/bin/tvservice -s").stdout.on('data', function(data) {
                if (data.indexOf("0x120002") !== -1)
                    exec("/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7", null);
            });
        } else {
            exec("/opt/vc/bin/tvservice -o", null);
        }
    }

So you are using “tvserice -o” which seems not to work for me.
would this be an alternative? Link

Executing the commands vom @E3V3A here Link brings the Monitor Signal back, but only 1 time.

Any idea?

Hi, using this command brings back the Monitor signal:

xset -display :0 -dpms
