I might have uninstalled some packages I shouldn't. For now, the only thing I've been missing is the lock screen. When I press Ctrl + Alt + L, or press the "Lock" button on the shutdown menu or I press the turn-off button and select "lock" nothing happens.

Do you guys have any ideas on what I can do?

Nope. In my case, none of the ways lock the screen. – robertokl May 7 '13 at 20:01

Install gnome-screensaver

sudo apt-get install gnome-screensaver
