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?

@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

I just implemented vcgencmd it looks like it is a bit quicker. I will check it out the next few days and will push it if everything works.

Yeah, but that only work with Rapsberry Piss , so if you want it to work on other devices, you need to use xset, and if you want to use xset on the Pi, you now also need to tell it that the blank screen should be black, with xsetroot -display :0 -solid black.

@e3v3a I think xset just blanks the screen without powering off the HDMI signal?
