My Ubuntu 12.04 suddenly stopped to auto-lock after X minutes. It doesn't matter how long I leave the computer idle, it NEVER turns the screen off and never locks the screen either.

I am using Gnome-shell. Under the Brightness and Lock menu, I have marked:

  • Dim screen to save power
  • Turn screen off when idle for 5 minutes
  • Lock screen after 5 minutes

I have already re-installed gnome-screensaver (no effect). Any ideas?

Did you do sudo apt-get purge gnome-screensaver, and then sudo apt-get update && sudo apt-get install gnome-screensaver? –  Max Tither Aug 18 '12 at 22:42

@cgubuntu1204, no success... purged gnome-screensaver and reinstalled it. Seems to have no effect. Still wont lock the screen. –  yurividal Aug 19 '12 at 19:14
    
Did it used to work? Did you do something recently that could cause this? –  Max Tither Aug 19 '12 at 19:16
    
It used to work. I have done nothing besides update-manager... Also, i have noticed that it is not related to GNOME, because even if i login on Unity interface, it still does not work –  yurividal Aug 19 '12 at 19:23

Start the terminal with Ctrl + Alt + T, and then type:

  1. sudo apt-get install dconf-tools
  2. Start dconf-editor
  3. UnCheck(if the option check means) org->gnome->desktop->lockdown-> disable-lock-screen (for verify - goto System settings->Brightness & Lock: check the Lock option enable or not).
  4. Close the editor.
  5. Restart the system & see the changes.
