<![CDATA[cronjob vcgencmd display_power]]>Hi guys, i am having trouble getting the magicmirror to turn the screen on and off with cronjob. I have used them before and it used to work and works with other installations with root /usr/bin…>/dev/null 2>&1 command but does not work anymore. I have tried all these variations and none work. I have used system wide cron with sudo nano edit and the reboot actually works…56cee79b-2240-43b0-91c0-78664a2d9871-image.png

cron is root by default unless u add another parm for the username

this was reported and worked thru in the fall.

I have 2 scripts and I call these scripts from the cron and not the actual vcgencmd

And in the scripts I run the following:

This works perfectly for me. Give it a go and let’s see if that works. I run an RPI 3B.
