Touchscreen shows only blue spinner

If you use an old version of our Raspberry Pi image, it may happen that you will not see our touchscreen interface, just a blue spinner. In this case your browser is too old.

Solution 1

Make a backup, install a new Raspberry Pi image and restore your backup to get the latest version.

Solution 2

Update your browser in a SSH console or use Global Settings Terminal  in our GUI with these commands:

sudo apt update
sudo apt install chromium-browser
sudo reboot

Depending on the used image the newer browser might lead to a new issue showing an incognito screen instead of the app. If this happens, edit the autostart script. 

nano /home/pi/.config/openbox/autostart

The relevant line looks like this:

chromium-browser --app-auto-launched --disable-pinch --incognito --noerrdialogs --disable-suggestions-service --disable-translate --disable-save-password-bubble --disable-session-crashed-bubble --disable-infobars --touch-events=disabled --disable-gesture-typing --kiosk --app=http://127.0.0.1:3344/modules/front2/app/app.html &

All you need to do is remove the –incognito parameter and reboot again.
