I can't lock my screen on ubuntu 13.04. Even installing gnome-screensaver the settings always show me the lock session as disable. Crtl+L doesn't work even clicking on lock on menu nothing happens. Any one can help me?

Is this question and its respectful answer of any use? –  Stef K Aug 21 '13 at 17:31
I saw this in a post... that works to me: gsettings set org.gnome.desktop.lockdown disable-lock-screen false –  Ricardo Aug 21 '13 at 18:08
If this is a solution then you may want to answer your own question for future reference for other to see. –  Stef K Aug 21 '13 at 21:27
