I seem to have a related problem where I created a new user (added in /etc/passwd and /etc/shadow and /etc/group) and I am able to login using the terminal, so it seems not to be the password, or one of the other entries. I do however fail to login using the desktop (graphical) login...

Any ideas on that?

Thanks

Woops, my bad.., but in that case the picture also shows the wrong connection...

What do you actually mean by 'logic voltage'? Is that the level where a '1' is detected or
the max input voltage for digital inputs?

So which of other 3 possible pins is the right one then? 2V, 2.5V, or 3V?

Or maybe the Onion Omega has a similar 'internal pullup' construct like the Arduino? In that
case you just change the circuit such that the button pulls 'down'.

@Steve-Fister Probably not. Reading the code the button is connected to pin 26, the other side probably is connected to +5V. Although this might work, it is good practice to also connect a resistor (like 10kOhm) between pin 26 and ground, to ensure pin 26 is at 0V when the button is NOT pushed.
