My MagicMirror screen keeps turning off

Sorry, but Debian buster and Debian stretch?
I guess you downloaded and installed an image with Debian, like from
https://www.raspberrypi.org/downloads/raspbian/
Debian Buster is the latest Debian version.With
lsb_release -ayou can find out which version you have.If your cronjob works for turning on / off the screen, then I guess you do not need to use the @xset parameters to turn off the screen.
This is what I currently have:
For Debain Stretch (screen always on):
$ cat /home/pi/.config/lxsession/LXDE-pi/autostart @lxpanel --profile LXDE-pi @pcmanfm --desktop --profile LXDE-pi @xscreensaver -no-splash @point-rpi @unclutter -display :0 -idle 3 -root -noevents @xset s noblank @xset s off @xset -dpmsFor Debian Buster (screen off after 900 seconds):
$ cat /etc/xdg/lxsession/LXDE-pi/autostart @lxpanel --profile LXDE-pi @pcmanfm --desktop --profile LXDE-pi @xscreensaver -no-splash point-rpi @xset s 900 @xset s blank @xset -dpmsNot sure what the other entries do, I just appended the @xset lines to the existing entries.
Will try what happens when I remove them a bit later. -

To answer myself.
lxpanel 0.10.0-2+rpt4 armhf LXDE panel pcmanfm 1.3.1-1+rpt7 armhf extremely fast and lightweight file manager point-rpi 0.20160905 armhf Locate the mouse pointer over the menu button xscreensaver - not installedUsing Debian Buster and a RPI 7 inch display, these settings should work for ‘screen always on’:
@point-rpi # locate the mouse pointer over the menu button @xset s off # don't activate screensaver @xset -dpms # disable DPMS (Energy Star) features. @xset s noblank # don't blank the video deviceI left
@point-rpias it sounds useful somehow; for screensaver settings not needed though.
Will test it now. -
Talking to myself :-)
The settings for Buster are not working.
My display goes to sleep after 10 minutes.
Perhaps because it isn’t a HDMI connected monitor.I found 2 interesting files though:
pi@raspberrypi:~ $ ls -als /home/pi/.xsession-errors 4 -rw------- 1 pi pi 2426 Aug 1 12:30 /home/pi/.xsession-errors pi@raspberrypi:~ $ ls -als /home/pi/.cache/lxsession/LXDE-pi/run.log 20 -rw------- 1 pi pi 17988 Aug 1 12:30 /home/pi/.cache/lxsession/LXDE-pi/run.logAlso see that this file is being used, so that seems right:
/etc/xdg/lxsession/LXDE-pi/autostart -
This works (running for 100 minutes at the moment of posting):
$ sudo nano /etc/xdg/lxsession/LXDE-pi/autostart @touch /home/pi/.started_etc_xdg_lxsession_LXDE-pi_autostart @point-rpi @xset -dpms @xset s off @xset s noblankNote: the autostart file does not like comments.
Reboot:
$ sudo rebootAfter reboot is finished, check:
$ ls -als /home/pi/.started_etc_xdg_lxsession_LXDE-pi_autostartThat will tell if the autostart file was used (timestamp should match reboot time).
Then check for set errors:$ grep xset /home/pi/.cache/lxsession/LXDE-pi/run.logIt should say 3 times
Launching xset, with 3 timesexit 0(for every set entry in the autostart file).Works for Raspberry Pi 7" Touchscreen Display.

I found 2 interesting files though:Wow, that’s a lot to take in. Thank you so much for your help, I’m going to try this during the week.

But my cronjob acts funny. Last night when I look at it after it was supposed to be turned off, the backlight was on but everything else was dark. Don’t really know whats going on, but I’ll take a new look tonight.

@evroom I’m stuck :(
I tried the code above, and it works, the screen doesn’t turn off, but now I can’t see the desktop, it’s black when I minimize the MM-window, and I can’t connect to my MM via VNC which I could before and that’s how I changed in the first place. -
Is here something useful ?
https://forum.magicmirror.builders/topic/1801/get-back-to-desktop
https://forum.magicmirror.builders/topic/5619/how-to-find-and-use-key-commands-in-mm-for-absolute-beginnersI personally only use VNC to “look” at the screen remotely and never use the Pi for anything else then displaying MM.
Not interested in the desktop.
I always login to the Pi using a ssh client, like for example PuTTY, or on my Mac the iTerm2.If you use Windows, then I would recommend PuTTY.
It is small and simple. -
@evroom
Thanks ever so much. I googled and found something that worked. Now everything is running as it should. Still have problems with VNC, but I installed TeamViewer, but I’m going to give ssh a shot soon. Thank you again -
So I have also been searching a lot for an answer to this question and been wondering why it have been so difficult to find a CLI based solution to this task.
I am using the “Raspberry Pi Imager” tool (on Window$) to prepare a USB stick (or SD card) and hereafter configure everything via SSH.
I know I could just use RDP or VNC to access and thus make this change via a GUI. But that’s to annoying, hence my need for a CLI based solution
Finally I found it in this thread (thank you @evroom !)
So this is just to help others with the same search that this [1] still works on the current latest RPI OS bullseye:
pi@magicmirror:~ $ lsb_release -a No LSB modules are available. Distributor ID: Raspbian Description: Raspbian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseyeWithout this [1] change the screen goes black after 600s (10m)
Which can also be identified by the “timeout value” returned by this command.pi@magicmirror:~ $ DISPLAY=:0 xset q ... Screen Saver: prefer blanking: yes allow exposures: yes timeout: 600 cycle: 600 ...After fixing it the value gets set to ‘0’
Right now I still see the screen after 16m (and counting…)How to
The config change can be applied in many ways (vi, nano etc) but I prefer this method (as it can be copy-pasted or be made part of a config-script).[1] I “just” add the three required lines to the config file:
printf "@xset -dpms\n@xset s off\n@xset s noblank" | sudo tee -a /etc/xdg/lxsession/LXDE-pi/autostartPS.: Before I found this I also tried these solutions (which all failed to solve the problem
A. in /etc/lightdm/lightdm.conf: xserver-command=X -s 0 dpms B. Enable VNC as a workaround for mutterI found (but did not try)
C. install xscreensaver and configure it to not kick inHTH (my first post here :-)
