      @shane1234 if u have the PIR module loaded, and do ctrl-shift-i (lower case letter i), it will open the debug env, and then select the console tab… do you see any errors?

      also, if u start from a terminal window, alt-spacebar, n will minimze the mirror screen so you can see the terminal window node_helper outputs… anything there?

      usually a module.js error kills with MM screen…

          mine is also freezing after the update.
          No difference if i connect via vnc or using the monitor.

          The only thing that does work, is opening the mirror in another browser (http://magicmirror:8080)

                Are you using MMM-PIR-Sensor?
                https://github.com/paviro/MMM-PIR-Sensor/issues/49

                I needed to delete the node_modules directory first. Then I ran npm install and the issue was gone.

                  I’m not currently using MMM-PIR-Sensor.
                  My problem was Enabling the Open GL driver. Using “dtoverlay=vc4-kms-v3d” or “dtoverlay=vc4-fkms-v3d” did not work. Remove the line and it was fine. (Temps seem reasonable 62deg)

                  "Enable the Open GL driver to decrease Electron’s CPU usage.
                  The latest versions of electron use an extreme amount of CPU power when no Open GL driver is loaded. This will result in an overheating Raspberry Pi. To solve this issue, use the experimental desktop Open GL driver by adding the following line to /boot/config.txt:

                  sudo nano /boot/config.txt
                  Add the following line:

                  dtoverlay=vc4-kms-v3d
                  ℹ️ Activating the Open GL drive can also be accomplished by using the raspi-config tool by running sudo raspi-config. Go to the Advanced Options menu and select A7 GL Driver. Next, select the G1 GL (Full KMS) OpenGL desktop driver with full KMS. Note that this option will be selected in the menu even when the GL drive is not yet configured."

                  Not sure what the issue is. But at least it works.

                    Ok, I cheated a little bit and completly wiped my SD card. Reinstalled Raspian, Magic Mirror and everything else from scratch, working great now!

                      I got mine working by following the advice in the second post on this thread:

                      https://github.com/paviro/MMM-PIR-Sensor/issues/39

                      Hope that helps others too.

                        @joela85 - I found that if you pull the SD card and plug it into a windows box, you can access the /boot path. That will allow you to edit the /boot/config.txt file and comment out the dtoverlay line. Edit in WordPad. Do not edit in Notepad.

                        Save the file, eject the SD card, put it back into your Pi. You should be able to SSH into your Pi once it boots.

                        I haven’t tried this procedure using an Ubuntu box, but it most likely will work.
