Pi 5 inch backpack touchscreen picture not working

by Nkirby13 on Wed Jan 23, 2019 8:05 pm

I got the touchscreen for Christmas and hooked it up. I even formatted the picture re scaling but its not scaled properly and it looks weird. It keeps looking like it's refreshing over and over and the touchscreen isn't working.

It looks like maybe you just haven't done the config step here:

Weird. The screen is working - it's showing stuff. It just seems like the scaling isn't set right for some reason. That's what the config file linked above *should* take care of.

Try commenting out the overclocking - the last line. Change it to:
Code: Select all | TOGGLE FULL SIZE
#arm_freq=800


Also check that you've done this:
use the raspi-config tool to force audio to the 3.5mm jack (not HDMI or auto). Not all screens support audio over HDMI, and in this case it may actualy interfere with the display.

All sorted! Is there a way to get a keyboard to come up when you touch in a text fill box? Like to sign in

I've never tried using one, but check out something called "matchbox-keyboard". Seems to be what a lot of people try using.
