I'm using lightdm as display manager in Raspbian GNU/Linux 9 (stretch), and I'm missing the login info messages, like "incorrect password, try again".
More precisely: upon boot or logout, if I incorrectly fill the user and password, the first time, it display the message "incorrect password, try again". But any subsequent incorrect tries, the same message fails to appear (I manage to login without a problem if I correctly fill in the user and password fields).
Also, I have a system which when booting for the first time, forces the user A to change password after inserting a default password like xyz. The flow should be "forcing password change", "insert old password", "insert new password", "repeat new password". But only the "forcing password change" message appears. All the others, the user is left to guess, which is inconvenient.
What could be the problem and is there a way to make all these messages appear? Where should I start looking...? Could it be the theme? I'm using Numix but have tried others and it doesn't solve it... Thanks for any pointers.
