What is this second login screen?

Question

Before being presented with the actual login screen, I am presented with another additional login screen.

Actual login screen:

Related bug report is #1577110.

Try removing your .Xauthority. Go to a TTY (Ctrl+Alt+F1) and type mv .Xauthority .Xauthority_2016-07-02. Then run sudo service lightdm restart and see if it fixes the issue. — anonymous2, Jul 02 '16 at 18:40
And BTW, the additional isn't technically a login screen; it's an unlock screen. — anonymous2, Jul 02 '16 at 18:41
You could also run chown -R user:user ~/.dbus, replacing user with your username. — anonymous2, Jul 02 '16 at 18:42
I also had this second unlock screen once after Unity crashed and kicked me out of my session. — Byte Commander, Jul 02 '16 at 21:09
@anonymous2: Let the user's environment tell you what the ownership should be: sudo chown -R $(id -u):$(id -g) ~/.dbus (and use sudo to insist on the ownership change). — waltinator, Jul 03 '16 at 02:32
@anonymous2 thank you! Your first comment solved my problem! :-) — orschiro, Jul 03 '16 at 07:01
Did you use the sudo command between the time that it started working and started working? — anonymous2, Jul 03 '16 at 11:00
Check the ownership on your .Xauthority. Is it owned by root? — anonymous2, Jul 03 '16 at 11:05
Looks like a glitch , GNOME's lock screen thinks your session is locked or something — Sergiy Kolodyazhnyy, Jul 03 '16 at 11:13

I assume it's better to continue the discussion at Bug #1577110 — orschiro, Jul 05 '16 at 19:02

mv .Xauthority .Xauthority_2016-07-03
sudo service lightdm restart

You could also try just changing it's ownership:

sudo chown user:user .Xauthority
sudo service lightdm restart

...replacing user with your username.
