I have a password set on my laptop running 12.10 smoothly, but the password requirement on boot from suspend or hibernation has vanished. It is still required for sudoing or boot from full shutdown. How can I get my password back?

Require password on wake is enabled, so that's not the problem. Also, in lightdm.conf there is no line saying autologin-user=. I can't exactly comment out a blank line.

Suspend/hibernate is enabled from the regular menu and both function correctly.


Go to System Settings > Brightness & Lock. There you can tick "Require my password when waking up from suspend".
