Run a startup script after GUI loads - Raspberry Pi 4 w/ Raspian

28 May 2020

If you’re running Raspian on a Raspberry Pi 4 and want to execute commands after the GUI has loaded, here’s how.

First, we’re going to open the autostart file.

# Note: Do NOT run in sudo mode. You will edit the wrong file!
nano ~/.config/lxsession/LXDE-pi/autostart

And we’re going to add the following:

@lxpanel --profile LXDE-pi
@pacmanfm --desktop --profile LXDE-pi

# Run a sample bash script
@sh /home/pi/your/

# Or a sample python script
@python /home/pi/

Hit Ctrl + X to write changes to disk, Y to confirm, and Enter to save the file.

That’s it! Go ahead and run sudo reboot to test it out!

I use this strategy to run a python server and React-powered UI for a digital photo frame.


Note: Make sure that you’ve run sudo raspi-config and set Boot Options to Desktop Autologin for best results.
