      @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

            Hope this helps

                I asked because I had problems with some modules which needed to much memory which results also in a black screen with white cursor.

                You could try to run without the 3 foreign modules to see if the problem persists.

                  I have another MM running on a Pi 4B that uses all the same modules without a problem.

                  But I will give your suggestion a try. Thanks for the tip

                      @BigTJ said in RPI 3B keeps going to blank screen (cursor showing):

                      4067:0824/230903.755884:ERROR:broker_posix.cc(46)] Received unexpected number of handles

                      this is the error

                      we don’t really know the cause.
                      u can try disabling the use of gpu

                      change package.json line to look like this

                      		"start": "DISPLAY=\"${DISPLAY:=:0}\" ./node_modules/.bin/electron --disable-gpu js/electron.js",

                        @sdetweil Thanks for the suggestion.

                        I’ll give it a go and let you know if it is successful.
