@MrNHQ Should be working with most displays, I'll double check it on my Pi setup in the next couple of days to make sure everything is as it should be.
To get it working with the Pi screen you need to edit /boot/config.txt
and change dtoverlay=vc4-kms-v3d
to dtoverlay=vc4-fkms-v3d
and add lcd_rotate=2
Headunit should work with QT_QPA_PLATFORM=eglfs /opt/headunit-desktop/headunit-app
only without xinit or sudo.
Getting this setup now similarly with a 3.5in backpack lcd
Hardware: Raspi 3b 3.5in lcd from waveshare
Using xinit, I got the same error:
Fatal server error: (EE) no screen found(EE)
And on running QT_QPA_PLATFORM=eglfs [loc of headunit-app]
, received the error:
Could not find DRM device!
Thoughts?
Looks like this guy rebuilt everything but I'd rather not...-___-
Hello,
I would like to try to put your project in my car. I dowloaded your image and tested it on my TV and an old VGA screen, both were working fine.
Then I tried on a 3,5 inch TFT screen (connected with gpio pins). using the
xinit
I got an errorFatal server error: (EE) no screen found(EE)
and usingQT_QPA_PLATFORM=eglfs /opt/headunit-desktop/headunit-app
I got:QXcbConnection: Could not connect to display
I also read the question about the official 7' inch screen not yet compatible. Would you know how I can use these screens? or which screens can I use?
