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…

this is on pi3 and i also tried modifying boot/config.txt file
Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d (changed to fkms)
max_framebuffers=2 -
@megagprime This is how I run mine. 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.

@mumblebaj ya even this didnt work, maybe i need to change my boot/config file back to kms
-
@megagprime anybody have any ideas why this doesnt work and should i change my boot file?

@megagprime
Did you ever figure this out? I’m having the same issue -
@Nneuland nope, still no dice. building a new mm now, will update
-
@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
