Allow Lightdm to lock the screen on automatic login

[Nerdopolis]

Feature request.

Light DM's automatic login should allow the option that it locks the screen as well.

KDM used to have this functionality, and it was great because it cuts down the startup time without requiring user interaction, without sacrificing the security of the automatic login being open to everyone that has physical access.

Status changed to 'Confirmed' because the bug affects multiple users.

Happy happy joy joy :)

I had a quick look at the code, does it automatically work with any session? (I just know that the auto-locking in KDM worked by setting the environment variable DESKTOP_LOCKED which is interpreted by some magic later on.)

It uses ConsoleKit/logind to mark the session as locked, and the session should pick that up.
