I have my settings as such, but when I power-on my laptop, it logs me right in, with no prompt.

Does anyone else have this problem?

enter image description here

  • The screen-shot shows the button as greyed out - therefore, just because it shows as off, it does not mean that is off. Are you using GNOME or Unity or what? – Wilf Oct 28 '13 at 22:52
  • Unity. A vanilla install of 13.10 – EdgeCase Oct 29 '13 at 11:40
  • The problem is the login manager, which will probably be lightdm. If your run system-switch-displaymanager as root, it will show you what display manger you are using. You may need to install 'system-switch-displaymanager' first - AND DON'T CHANGE ANYTHING WHEN YOU DO RUN IT, AS OTHERWISE YOU MAY HAVE SOME DIFFICULTY LOGGING IN, LOCKING SCREEN etc. – Wilf Oct 29 '13 at 13:05

I had this problem on my desktop after I had set on autologin and then set it off for myself. Even though I set it off in the user settings box, it remained on and automatically logged my in without requiring a password. I finally fixed it by locating and removing the following line in the /etc/group file: "nopasswdlogin:x:118:username"

Try editing the Display Manager configuration as root, using nano.

One of these for LightDM (I think that it is now default):

[wilf@comp ~]$ ls /etc/lightdm
keys.conf      lightdm-gtk-greeter.conf        users.conf
lightdm.conf   lightdm-gtk-greeter.conf.old
lightdm.conf~  lightdm-kde-greeter.conf

It will probably be lightdm.conf, so run:

sudo nano /etc/lightdm/lightdm.conf

For GDM (Gnome's)

sudo nano /etc/gdm/custom.conf

And for KDM (KDE's)

sudo nano /etc/kde/kdm/kdmrc

Look in the .conf files for 'Auto' - open each in a text editor (e.g. gedit) , Ctrl+F in each and type 'auto'

BEFORE ANY CHANGES ARE MADE, backup the configuration file you are editing: For example, if you editing /etc/lightdm/lightdm.conf, run this first:

cp /etc/lightdm/lightdm.conf /etc/lightdm/lightdm.conf.old

After a 13.10 vanilla Install, go to User Accounts Have a look to the unlock button (upper right corner)

After authentication, you will be able to switch Automatic Login to OFF
