4 inch RPi LCD displaying MM not working

aecandroid

@sdetweil thank you for your help.

I’ve checked my mm.sh file and it reads as follows. Not sure where to go from here?


cd ~/MagicMirror
node serveronly &
sleep 30
xinit /home/pi/chromium_start.sh

@aecandroid look at that /home/pi/chromium_start.sh

aecandroid

@sdetweil I did, sorry, should’ve mentioned.

This is the code:


/bin/sh
unclutter &
xset -dpms # disable DPMS (Energy Star) features.
xset s off # disable screen saver
xset s noblank # don’t blank the video device
matchbox-window-manager &
#midori -e Fullscreen -a http://localhost:8080
chromium-browser --incognito --kiosk http://localhost:8080/

@aecandroid what version are you running? none of that is current…

use my installer script, it handles piw -4, odroid, jetson nano, any unix variant.

see the readme here

https://github.com/sdetweil/MagicMirror_scripts

it will setup to launch chrome against serveronly exactly as it appears you have done…

oh, you need raspian buster… jessie and stretch are too old now

@sdetweil Thanks for the help. I tried to start over from fresh. I’ve installed buster lite and completed a fresh install of MM and followed the bash -c "$(curl -sL… commands listed. I still am not having any luck getting MagicMirror working on the 4 inch display. Everything is fine right up until I do the Waveshare driver install and then do ./LCD4-show. Once I do that, I can see the device reboot, the HDMI no longer works and on the small LCD, I see the command prompt boot to pi@raspberrypi:~ $. From this point, I can no longer get MagicMirror to run, even if I try to run ./LCD-hdmi, MM does not start working again with HDMI. Something with the install of the Waveshare drivers is killing MM. I am genuinely at a loss.

@aecandroid can’t be lite… needs to be the graphical version…

aecandroid

@sdetweil in the immortal words of Homer J. Simpson - Doh! I’ll have to give this a try later this evening. Is there any reason the GUI version will work and the lite won’t with the small LCD?

sdetweil

@aecandroid u MUST HAVE the gui version for electron to run, or chromium

aecandroid

@sdetweil Right, so before I get ahead of myself and balls it up again. I have just installed Raspbian Buster Full 2020-02-13 image and going through the initial setup on my Pi Zero W. Should I do the Waveshare drivers for the 4 inch LCD first and then do the MM scripts on your github? Or should I run your scripts first, configure my MM, then do the Waveshare driver?

@aecandroid i would get the hardware working first
