    @sdetweil said in MM on Pi Zero fails after being off for a few days:

    ./run-start.sh

    When I run

    chromium-browser  --app=https://cnn.com
    

    I get command not found, so I tried

    chromium  --app=https://cnn.com
    

    and I get Illegal Instruction.

    i tried your script, and I get the text on screen about no helper found etc, then it gets stuck when trying to fetch the calendar data. I can access it from another computer but the pi is still blank on screen

    Edit: It does seem to go through the calendar step but just very slowly, still progressing to each successive calendar now. I’ll leave it running and see if it eventually successfully starts.

      @kellogg76 no… its stuck with the chromium-browser not loading…

      I think u need to reinstall the chromium browser…

      this means there was an update , or there is an sd card problem…

        @sdetweil looks like the quickest fix is to re-install again. It’s a pain as I probably have to do this about once or twice a year. It can be working great then either the power will unexpectedly go out or I’ll shut it down for some reason and then it takes a full wipe and re-install to get it working again.

          @kellogg76 use my install script

          see here
          https://github.com/sdetweil/MagicMirror_scripts

          rename existing MM folder out of the way
          run the install script… it does everything…

          (well, not install chromium browser)
          sudo apt-get install chromium-browser

              @sdetweil I renamed the old MM directory and ran your script

              bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
              

              Everything went successfully, I can see the display from other computers but the pi just sits at a terminal prompt, is there something I need to do to start things off?

                the run-start.sh script depends on it

                  @sdetweil Yes, and then rebooted for good measure. Could it be anything to do with me running Raspbian Lite and not Desktop?

                    @kellogg76 you MUST run desktop for chromium to work…

                    from the shell, do

                    pgrep Xorg

                    it should return a number

                      @sdetweil It seemed to work well without it in the past, has something changed?
                      I always found the Desktop version really laggy on the Zero so try to avoid it when not necessary.
