I want to open my chromium web browser in fullscreen-mode and open an URL that I get from a different config file. All this should happen automatically after booting. For testing, I tried to execute a terminal command in python first of all with
os.system(chromium-browser --start-fullscreen www.google.de)
But it throws an invalid syntax error.
Is there a possibility to start the browser with something different than with a systemd service file?
I am running this on an RPI 4 with the newest version of Raspbian.
Thank you for your advice
