Which Pi Distro?
MX Linux (no systemd?) may be very different to Rasperian etc.

autostart

1. Create the autostart directory:
mkdir -p /home/pi/.config/autostart

2. Open a new text file in your preferred editor.

3. Add the following three lines:
[Desktop Entry]
Type=Application
Exec=mousepad
Replace mouespad with the command of your choice.

4. Save in /home/pi/.config/autostart with a name ending in .desktop e.g.
mousepad.desktop
