MM current version on Raspberry Pi 5 cannot turn off monitor
-
@1a2a3a said in MM current version on Raspberry Pi 5 cannot turn off monitor:
vc4.force_hotplug
That does appear to work! So far I have tried it on two different Pi 4 instances, and each responded to a script called in crontab to turn off the monitor display, and then a script to turn it back on, as expected.
Thanks.

@1a2a3a Thank you Thank you Thank you… That worked for me as well… Message me, and I will get you a pizza like I promised to anyone who could get my pi4 running latest rasbian to turn off the monitor. Adding vc4.force_hotplug=1 to the end of the line in /boot/cmdline.txt did the trick along with using wlr-randr!!
I’m serious about the pizza.

@jbat66 all good mate. I’m likely in a different geographic region to you. But anyway it was an issue that someone in GitHub that resolved for me so I can’t really take credit. I would point you to the GitHub but it was quite awhile back hence I can’t find the link anymore, therefore I went into my txt file and gave you guys the code.
-
@jbat66 I know this thread isn’t about getting MMM-Remote-Control to update with this but I was curious if you know how I could go about that.
-
@devonian69 Do you mean just a normal update for the module?
-
Hey guys,
So how did you get this to work? vc4.force_hotplug ive added that to /boot/firmware/cmdline.txt
But now what?
Im running Raspbian on a Pi 5, so not sure if all of this is even for bookwork :(
Thanks

@liminal1 note that rapios on pi4 and 5 use a new display manager called Wayland.
so all the commands for display MGMT have changed. see the commands posted above.
or set the os back to x11. see the raspi-config command

or set the os back to x11. see the raspi-config commandI did try those commands, they are not working for me. Maybe I need more context for that (which is essentially what I was asking for :) Or I switch back to a slower and less efficient display model that negates having a Pi 5. Is that a correct asumption?
Maybe I wasn’t clear, but Im just asking if anyone does have it working on the Pi 5 with Bookworm. What did you use and how did you do it?
Thank you :)
-
@liminal1 the posts above say it was working on bookworm.
-
@liminal1 doesn’t matter 4 or 5. As long as bookworm wayland, it’s working fine. For what’s worth, I’m on a 5.
