MMM-Remote-control all working except for monitor on and off

karsten13

I can’t test this myself at the moment because I have no pi left for a fresh install.

I had to reinstall my MM

what does this mean exactly? Did you setup MM-OS from scratch?

diemen112

yes completely from scratch, i used the latest MM-OS version:
(2022-03-08_2022-01-28-magicmirroros-bullseye-armhf-lite-0.3.0)
and reinstalled all the modules on a RP3b+

@diemen112

you are using a nightly build which is not an official release.

I was not aware of a bullseye version and this setup was never tested with bullseye.

So I recommend to use a buster version.

@karsten13

@diemen112 @karsten13 For bullseye I needed to change the display driver to the fake kms one (dtoverlay=vc4-fkms-v3d in /boot/config.txt) to have any effect of vcgencmd.
Afterwards vcgencmd only worked from the host, but not from @karsten13’s docker container. There I ran into the same problem with my MMM-Gestures module:

[09.10.2022 17:54.49.927] [LOG]   Sun Oct 09 2022 17:54:49 GMT+0200 (Central European Summer Time): exec error: Error: Command failed: vcgencmd display_power 0
vcgencmd: error while loading shared libraries: libvchiq_arm.so.0: cannot open shared object file: No such file or directory

I fixed it by mounting two more files from the host, my volume mounts now are:

    volumes:
      - ../mounts/config:/opt/magic_mirror/config
      - ../mounts/modules:/opt/magic_mirror/modules
      - ../mounts/css:/opt/magic_mirror/css
      - /tmp/.X11-unix:/tmp/.X11-unix
      - /opt/vc:/opt/vc/:ro
      - /usr/bin/vcgencmd:/usr/bin/vcgencmd
      - /usr/lib/arm-linux-gnueabihf/libvchiq_arm.so.0:/usr/lib/arm-linux-gnueabihf/libvchiq_arm.so.0
      - /usr/lib/arm-linux-gnueabihf/libvcos.so.0:/usr/lib/arm-linux-gnueabihf/libvcos.so.0
