@Rael Gugelmin Cunha (rael-gc): You are probably right. The changelog for the "unity" package says: "* Refactor the way UserAuthenticator is created and passed around. Handle failures to create new threads and fallback to a "Switch to greeter..." button in case of failure. (LP: #1311316)"
It seems that the initial bug from LP: #1311316 of "Sometimes (but not always) after locking the screen there is the situation not having any input field where I can type the password to unlock the session again." was addressed with a workaround, but this workaround has caused even more problems. I never had the issue of not having a password prompt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733557 Title: Login screen showing Authentication Failure Switch to greeter...
