      @sdetweil Thanks so much for your help. xrandr won’t control the brightness on the Pi 4 even with switching to the X11 backend. I tried your suggestion of increasing the swap file (I increased it to 2048M) and then my system ran from about 11:30 pm to 6:20 am and then froze. When it froze, the entire Pi OS froze–not just the MM app. Do you have any other suggestions about what might be causing the Pi to freeze while running MM?

      Tbanks so much for your help!

            I have other projects running on other Pis and they have been running with 2 years uptime. I think it is something about the Magic Mirror application and maybe the Raspberry Pi 3B. I would switch to a Pi 4, but like I said, I can’t control the brightness with the Pi 4.

              @raspberrypi9 MagicMirror is just a browser w javascript

              unless there are gpio modules

              does this pi3 have a fan?

              do you get the same on the 32 bit os?

              the stack errors sound like hardware problem

                @sdetweil I am using a gpio module and a PIR motion sensor. I don’t have a fan. I am running bullseye 32-bit os. Should I try changing any of those things?

                    this can be caused by a specific module so you can try disabling one by one …
