      ok i checked some more and did some tests

      73aa8bb5-2eeb-4bac-888c-2822ba96a7ad-image.png

      when I execute the following I get the error message that I also see in the log

      /usr/bin/wlr-randr --output H DMI-A-1 --off
      failed to connect to display

      also running the sh files via putty gives the error
      it seems that the command:
      /usr/bin/wlr-randr --output H DMI-A-1 --off
      the error message gives the question is this command incorrect or is there an underlying problem?

        @Sam-0 Can you run the following from the command line and she your results:
        wlr-randr
        ls -als /run/user/1000/wayland*

        Share your results. Either the wayland-1 is different as indicated by @evroom or HDMI-A-1 is actually a different version on your system.

        Share the results from the above and we take it from there. Also, @evroom has indicated the there is supposed to be a space before /home on the crontab.

            So as stated before you most probably need to change wayland-1 to wayland-0 in your scripts.
            Give it a try.
            Furthermore the .lock file may cause a problem, but I guess this will show in your error log.
            And temporarily change the times in your cronjob to speed things up a bit.
            Waiting till ten and midnight is not really necessary :-)

              @evroom *.lock should not cause an issue. I have same on my system and no issues with it. I agree with the wayland-1 change to wayland-0.

                should it be modified in this way?

                output HDMI-A-1 --on
                Into
                output HDMI-A-0 --on

                  No, like this:

                  export WAYLAND_DISPLAY=wayland-0

                  In both scripts.
