startx doesn't load python tkinter app openbox

Im using openbox to control a tkinter app. My app is t.py and is located in ~.

This is my ~/.config/openbox/autostart:

python3 ~/t.py

This is t.py:

import tkinter as tk

root = tk.Tk()
label = tk.Label(root, text="Hello")
label.pack()
root.mainloop()

When I run sudo startx, I can see the cursor pop up then hide, but after that its just a black screen. I am running these commands over ssh as well. I had this working before with a separate .py file but can no longer get it to work. I am running this on a Raspberry Pi Zero 2 W with a HDMI screen. The Pi is installed with the latest Raspberry Pi OS Lite.

Try using the following approach which does not depend on what window manager is used:

  • create a <anyname>.desktop file inside ~/.config/autostart/ folder
    e.g. ~/.config/autostart/demo.desktop

  • enter the following content inside the above file:

[Desktop Entry]
Type=Application
Exec=/bin/bash -c "/usr/bin/python3 $HOME/t.py"

The above works in my VM running Debian Bullseye with Raspberry Pi Desktop.

As per the man page for openbox, you need to rename the startup script as autostart.sh
and also make it executable using
chmod +x ~/.config/openbox/autostart.sh.

Finally, ensure you put an & sign at the end of the command.

python ~/t.py &

inside the autostart.sh file.
