      Sorry, but Debian buster and Debian stretch?

      I have a cronjob to turn off the screen at 11 pm until 6 am, which works, but other than that I want the screen to be on. Is it possible to change 900 to 61 200 (17 h) instead?

        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 -dpms
        

        For 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 -dpms
        

        Not 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.

        MagicMirror version: 2.30.0
        Raspberry Pi 4 Model B Rev 1.5 (8 GB RAM)
        Raspbian GNU/Linux 12 (bookworm)

        Test environment:
        MagicMirror version: v2.30.0
        Raspberry Pi 3 Model B Plus Rev 1.3 (1 GB RAM)
        Raspbian GNU/Linux 12 (bookworm)

          Not sure what the other entries do

          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 installed
          

          Using 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 device
          

          I 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.log
            

            Also 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 noblank
              

              Note: the autostart file does not like comments.

              Reboot:

              $ sudo reboot
              

              After reboot is finished, check:

              $ ls -als /home/pi/.started_etc_xdg_lxsession_LXDE-pi_autostart
              

              That 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.log
              

              It should say 3 times Launching xset, with 3 times exit 0 (for every set entry in the autostart file).

              Works for Raspberry Pi 7" Touchscreen Display.

                  I tried the code above, and it works on stretch, I screen doesn’t turn off. 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.

                      @EhsanMomeni81

                      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-beginners

                      I 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.
