Ask for password at login

[sgage]

During my latest installation of UM (20.04), I told it to log in automatically without asking for my password. I decided to change that so that my password is required. However, even though I set it for "Ask for password" in Users and Groups, it still signed me in automatically.

So poked around in /etc/lightdm to see if anything was going on with lightdm.conf. Sure enough, that file consisted of one entry:

[Seat:*]
autologin-user=sgage
autologin-user-timeout=0

which persisted no matter how I ticked the box. I just deleted /etc/lightdm/lightdm.conf, and was asked for my password on my next boot.

The bug has been there for at least three years

Bug when selecting auto login during install

However, if you then go into users and groups and tell it to require the password on login, it still does an autom…
