Hi to all members!
First I want to thank all contributor for the Magic Mirror project. I really enjoy this project to build my own mirror and learn new things.
I have a pi 3b+ running on the latest OS :
stretch V9.6
I have installed MM and followed all documentations then implemented a few modules.
the defaults one they are working fine ( some are commented such as alert and notifications (For debugging the blank screen issue I have and make sure the cause was not those modules)
MMM-AssistantMk2 & MMM-Hotword ( perfectly works )
MMM-NowPlayingOnSpotify working fine but commented for as well because getting too much errors ( when nothing was played )
mmm-systemtemperature : Works OK
MMM-DarkSkyForecast :Works OK
MMM-Hue : Works OK
MMM-Traffic : Works OK
MMM-PIR-Sensor (To turn off&on the HDMI Port) : Works OK
You will tell me all “works OK” so what’s wrong with you guy :)
Well after I start my MM all is “work ok” (Again)
The Pir sensor delay works and well shutdown the HDMI port and it comes back when a movement is detected. My delay is set to 10 mins and if I come back after 15mins the screen is back ON, So far so good .
Now my issue : When I come back after a while let’s say an hour or more, the PIR sensor turn ON the HDMI port and my screen goes on.
Then surprise I get a blank screen.
I know I’m not in screen saver mode because after a VNC connection I see the little popup on screen and I can see the mouse moving as well.
My conclusion is that the MM is in a kind of “sleep” mode waiting to be wake up.
I can bring the MM modules back on screen for example by giving input via the Hotword/assistant module so when I say “Jarvis” the hotword is detected and MM & all modules directly come back on screen.
No error in the MM error log from PM2 nor in the out file.
Dev mode ( Shift CTRL I ) show me that the modules are still well receiving notification from other modules )
Before posting this thread here as I said I read the full installation documentation and more. I did many research for a similar problem and didn’t find . I looked at many places and applied several solutions. Unfortunately without success ).
It look like it’s a matter in the MM code itself ( But I maybe wrong I do not want to bother anyone by saying this ) Just a personnal thought.
Here is my setup :
/etc/lightdm/lightdm.conf
[SeatDefaults] ( I had to create this entry in the file )
xserver-command=X -s 0 -dpms
As well added to
[Seat:*] ( which was existing prior editing the file )
xserver-command=X -s 0 -dpms
Just in case ( but I have added this after and that didn’t help )
The file /etc/xdg/lxsession/LXDE-pi/autostart
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash
point-rpi
@xset s noblank
@xset s off
@xset -dpms
And /etc/xdg/lxsession/LXDE/autostart
@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash
@xset s noblank
@xset s off
@xset -dpms
I didn’t make it in /.config/lxsession/LXDE-pi/autostart because when creating this file my system boot in openbox and not in desktop session.
And I want to keep the desktop for other reason.
I installed xscreen and turn of powersaving on screen and screen saver.

Finally I’m up to date on MM and all Modules.
I didn’t use the OpenGL driver in /boot/config.txt as in was generating error in the logs, and my pi is Fan cooled So I don’t worry for now about system temp ( always around 50°C) and CPU usage ( around 40% when MM + VNC are running )
So if anyone have clue / good question to ask my to help me dig out this issue and resolve it you are most that welcome !!! I hope that this post was not too long but I wanted to give as much details as I can.
If you need any other info feel free to ask me.
Thank you again for all your work and help .
