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

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.

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

@michaels It looks like you don’t use pm2 to run MagicMirror.

How did you install MagicMirror, did you use the automatic installation?

@bobbythemoh You may also try to uninstall xscreensaver

@bobbythemoh Did you reboot after correcting the option?

@bobbythemoh I guess you have some sort of other “power saving” feature activated I am not familiar with. MMM-Loxone directly toggles the HDMI output on or off. It isn’t displaying a black view on top of the screen.

Please verify your /boot/config.txt!
In one ofyour posts you wrote hdmi_blanking_1 but it should be hdmi_blanking=1.

@kalleK This looks like you already have an instance of MagicMirror running. Do you use pm2 to run your MagicMirror on startup?

If you use pm2 you can run pm2 restart MagicMirror to restart the MagicMirror.

@bobbythemoh btw. Just blacking out the screen is not realy saving much power if the backlight is still on… You just have to install MMM-Loxone, it will switch off the HDMI signal everytime the lights go out, your monitor will handle the rest (you might check your monitors Power saving setting).

@bobbythemoh This sounds like you use some kind of other „screensaver“ which just displays a black screen instead of switching off the HDMI Port. I think you somehow enabled „screen blanking“.
