Set a password, yet it logs in without one

Question

My account is an administrator; I'm using Ubuntu 14.04LTS.

I've set a password and set automatic login to OFF, yet when I wake up from suspension or reboot if I just press Enter or type in anything then it logs me in.

How should I proceed?

Answer 1

Easy:

• Click the gear icon in the top-right corner of your screen:

  

• Click System Settings, then Brightness & Lock:

  

• Click the Lock switch until it goes into the On position and ensure the Require my password when waking from suspend is ticked.

Done! ;-)

If that doesn't work:

Create a new user on your system and see whether that user does work. If that's the case (in the below example we'll use steam-gamer and steam-gamer2), just do the following:

1. Open the file manager

2. Browse to the /home/steam-gamer directory

3. Copy (don't move!) all the files from Downloads to /home/steam-gamer2/Downloads

4. Check you did a good job.

5. Now delete /home/steam-gamer/Downloads

6. Go back to step 3 and repeat for Documents, Videos, ...

7. After a couple of days to allow you to ensure you didn't forget to copy anything, just delete steam-gamer together with it's home directory by issuing the following command:

   sudo deluser steam-gamer --remove-home
   

Answer 2

I like using the terminal:

1. Enable Screen Lock

   gsettings set org.gnome.desktop.screensaver lock-enabled true
   

2. Enable Lock on Suspend

   gsettings set org.gnome.desktop.screensaver ubuntu-lock-on-suspend true

To disable, use false instead of true.

Answer 3

First make sure you have all the security updates installed. If this is not the issue, check if the problem appears when you log into other graphical environments. You can also test the manual lock with "Ctrl + Alt + L". If you use a screen saver, take a look at this one.

The brute force approach is to hand edit /etc/lightdm/lightdm.conf, adding a # character to the beginning of every line starting with autologin.
