Support for official Raspberry Pi Touch Display #14

Closed suhrmann closed 5 years ago

suhrmann commented 6 years ago

I connected the 7" Raspberry Pi Touch Display and am using the latest headuni image (image_2017-08-17-Raspbian-viktorginos-headunit-lite.zip) as is with the changes from Setting up the PI: Setup the WiFi, Rotate the screen, Increase the GPU memory and Enable SSH.

After apt-get update && apt-get upgrade I started the headunit successfuly!

xinit

But the touchscreen-input doesn't work properly. It rarely recognizes touch-input - but if it does, the input is correct. I assume the error is linked to the log entries 

InputFactory: Input device: "auto"
InputFactory: No valid device found use Null device instead.

Full log on pastebin.

OpenGL

Trying to launch it with OpenGL gives the error

QXcbConnection: Could not connect to display

Full log on pastebin.

I found the reason and the solution for the input-problems with xinit After removing lcd_rotate=2 from the config the headunit works 🎉

if you run it with QT_QPA_PLATFORM=eglfs /opt/headunit-desktop/headunit-app it runs with the VC4 driver

viktorgino commented 6 years ago

you can make it permanent by changing it in /etc/environment

is from welle.io :). I'll look into trying to tag debug messages, it does get confusing sometimes

Even with using the VC4 drivers, the display stays black. And the screen ration is wrong (except it's the hu-content ratio). If I don't add sudo the screen stays black as well and the device (AA) isn't recognized. Log
