I have a raspberry pi 3B+ and a 7" touchscreen. Octopi image is installed on the sd card. I booted up and entered the user 'pi' and the password 'raspberry'. Now I see 'pi@octopi: ~$. What next?
sudo usermod -a -G tty pi
sudo usermod -a -G dialout pi
even though it says in the get help guide that it should say 'pi@raspberrypi:~$' but I didn't/don't know what else I should try.
The raspberry is not connect to a PC and/or Windows, just to the touchscreen. I don't even know if it is connected to the internet. I tried to install a touch driver for the screen but it failed to connect to github.
