3)I have opened /etc/rc.local and placed 'sudo python /home/pi/tkinter.py &' but it didnt work

please provide me a solution which runs when raspberry pi boots up.Thank you

Answer 1

As you've created a tkinter program, I'm assuming you're running it in X windows. So the question is more 2 questions:

• How do you start X windows automatically on boot?
• How do you start an app automatically when X windows starts?

To start X windows, you can enable "boot to desktop" from raspi-config.

To start an app automatically when X windows starts, add a line to /etc/xdg/lxsession/LXDE-pi/autostart. It should look something like:

@python /home/pi/tkinter.py

Answer 2

I found a helpful article here: Run a script on startup

But it sounds like you've tried the first option. Perhaps you need to make the script executable? Try the following :

chmod +x /home/pi/tkinter.py
