      Re: new script for screensaver disable

      Hi all,
      I’m having a big problem with my magic mirror. It looks as though my RPI 3B keeps going into screensave. After a while I get a black screen with a white arrow cursor.
      I have gone through all the usual documented ways of turning off screen save ie
      consoleblank=0 in cmdline.txt,
      Screen Blanking’ option in the Raspberry Pi Configuration tool,
      Xscreensaver is not installed,
      Adding to /etc/xdg/lxsession/LXDE/autostart;-
      @xset s noblank
      @xset s off
      @xset -dpms,
      Adding to /etc/kbd/config;-
      BLANK_TIME=0
      POWERDOWN_TIME=0,
      Adding to ~/.bashrc;- setterm -blank 0 -powerdown 0,
      Adding to /etc/lightdm/lightdm.conf;- xserver-command=X -s 0 -p 0 -dpms,
      etc etc…

      If I connect using VPN I still only see a black screen with cursor.

      Any help with this really frustrating problem would be greatly appreciated.
      @sdetweil - I found references to an old script of yours but could not access it to try it on my MM.

      Thanks

          Many thanks

          I ran your script with the following result;-

          disable screensaver via gsettings was true and uint32 300
          disable screensaver via lightdm.conf
          lxsession screen saver already disabled

          Does this mean the screensaver is already off or that the script has disabled the screensaver?

          Thanks again

              Thanks for your help.

              This has been a problem for a long time. The mirror is being used headless so having to restart over and over again has spoilt the usefulness of the mirror. Hopefully that is all sorted.

              Will let you know after testing.

              Thanks again.

                @sdetweil Unfortunately I am still getting the black screen with mouse cursor.

                I’ve installed a new OS from scratch and Installed a clean version of MM, installed the modules from scratch but the problem persists.

                When the MM has gone to black screen I cannot use CtrlM to minimise the MM window but I can use CtrlR to force a re-read and this brings the MM back on. Any ideas what can be causing this?

                Thanks

                      Thanks BigTJ
