oot into recovery
Hello!
Thanks for you suggestion. I found the screen, selected 'Wipe cache' but nothing more happened (contrary to the other buttons 'wipe data' and 'wipe system', I didn't answered 'yes' to the confirmations that were asked).
I rebooted anyway, but the situation remains the same...
Maybe I'll need to reinstall Ubuntu, but I know the developer mode has to be selected. Yet, I can't reach the menu to select it...
