Re: How can I change the username properly?

The pi user is probably still being called by auto login. I change the line "ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM" in /etc/systemd/system/autologin@.service. Replace "pi" with your new user name. Open /etc/lightdm/lightdm.conf and find the line autologin-user...

Re: Pushing 2 buttons at once

Can you not just use:

Code: Select all

while True:
	s = GPIO.input(BUTTON1)
	m = GPIO.input(BUTTON2)

	if s == False:

	if m == False:
		print'button2'
	if s == False and m == False:
		print 'Both pushed.'
	sleep(1)

Open a console and with the device unplugged run the following command:
ls -al /dev/tty*
Plug the device in and run the command again, your device should be the one that's just appeared.

Re: Black Rectangle Top Left Corner Of Screen

I've just upgraded the firmware using rpi-update. Everything went well, no errors but after rebooting I still have the small black rectangle :(

Re: Galaxy Tab 4 10.1 Screen for display

I've been using the new Rpi 7 inch touch screen as a control screen for a project. It's been really good so far.
