Jarno Suni, in reply to #11 and #13:
a) you need to be logged in, then follow the steps: - lock the screen with "Shutdown > Lock Screen" ; - on lightdm screen, just do ctrl+alt+F7 : you arrive on the desktop, without typing any password. b) althought the webupd8 article mentioned Ctrl + Alt + 7, i'm sure he wanted to mean Ctrl + Alt + f7 once that's the correct shortcut to go back from any tty console. After all, is there a way to fix this kind of security issue? I'm not a dev. I'm just a QA tester and so far I can only assure that anyone can have access to a locked machine running Lubuntu 13.10 just hitting the shortcut Ctrl + Alt + f7 without any need to input username or password. As said before, the machine was locked and before that there was a username logged in.
