      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

        Enable DRM VC4 V3D driver

        dtoverlay=vc4-kms-v3d (changed to fkms)

          @megagprime This is how I run mine. I have 2 scripts and I call these scripts from the cron and not the actual vcgencmd

          3fdefb68-5776-47df-8d84-77b37e55d927-image.png

          And in the scripts I run the following:

          cacceb58-583d-425f-8249-960a351a4e7f-image.png

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

                    @megagprime @Nneuland depending on the board firmware, the vcgencmd may or may not work

                    this was reported and worked thru in the fall.

                      @sdetweil hi there, i still dont see a fix or alternative workaround. The commands themselves work i just cant get it to work with cronjon :(

                        @megagprime what user is cron executing them as?

                        what user do you use when testing?

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