You are not logged in.
Display Manager:
1) User login with password.
2) Allow choice of xsession based on .desktop files in /usr/share/xsessions/
3) Allow choice of locale, from what is installed on system (ie switch language).
4) Display users and choose one to login.
5) Bypass choice of default user, input password only.
6) Allow auto-login.
7) Look pretty.
Most of these can be done from the command line, but with more complication, especially 3).
Thank you for the list, appreciate seeing the details. Thinking about it - having autologin on encrypted partition, which requires password anyway - actually it'd make sense to configure a setup without display manager. If there is "change of user", that's intended to be always from within the session. I don't change the desktop or locale often.
As a side note I can remember looking for a way NOT to get the user list shown in the display manager, but it was not possible. On the other hand I'm not sure how many users do care about having a DM-agnostic system, but it's surely a cool feature for those who care about it.

...looking for a way NOT to get the user list shown in the display manager, but it was not possible.
It is possible. In fact it's the Debian default! We changed it to display users in response to requests here on the forum.
If you want to hide the users at login, edit /etc/lightdm/lightdm.conf or Menu>System>Login Settings
Find greeter-hide-users in the [Seat:*] section and set it to true:
greeter-hide-users=true

^Indeed, thank you for the correction. The issue I was recalling wasn't about hiding the user list. It was something about getting only the logged in user showed after a lock screen. According to the last post in that thread (created a few weeks later) it looks like this feature - or similar - might have been available. Right now luckily I don't have to change the username after a lock screen, only typing the password is required.
