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

go to search , type Unity, in the options displayed find and double click on option "Unity Tweak Tool", a windows opens inside that you will find main options like


Windows Manager



under "system" there are 3 sub option "Desktop" , "Security", "Scrolling"

  • click on security, under security tab do a check on option "Desktop Lock"

I am adding this solution just in case if unable to find the option.

Thanks for the all previous post's. very helpful and informative.

None of these worked for me, but I found some info in this bug report.

As a result of what I read in the bug I ended up doing this:

sudo mv /etc/xdg/autostart/light-locker.desktop /etc/xdg/autostart/light-locker.desktop.bak

That seemed to do the trick.
