Ok guys, I'm facing an other problem with the raspberry:
I've created two scripts main.py and send.py that are executed through the lxterminal by the system at the raspberry startup using a .sh file. The problem is that on the raspberry 3A+ the two scripts only start when I move the mouse or I press a keyboard button, while trying the same script on a raspberry 3B+ they automatically start. I don't know if this is caused by a the different software version between the two raspberries or something else, but I can't understand why the same script automatically starts only on the 3B+ system.
Do you have any idea on how to solve this?
