How to disable screen lock in Ubuntu 14.04 / Unity? [duplicate]

I disabled the lock in the "Brightness & Lock" but I still get the lock screen when is resumes/wake from suspend. Although the option "Require my password when waking from suspend" is unchecked


There is two steps involved into completely disabling the lock screen in Unity.

  1. Go to Brightness & Lock panel from the Unity Launcher. And set Turn screen off when inactive: to Never
  2. Install "Unity Tweak Tool" with sudo apt-get install unity-tweak-tool. Run it from the Launcher and select System > Security > Enhance system security by disabling Desktop lock
