Switch Back to Previous LockScreen in Ubuntu 14.04 Unity

Last updated on May 20th, 2014

Ubuntu 14.04 Unity now has its own screen locker which looks identical to the LightDM greeter – the default Unity login screen. For those who prefer the previous lockscreen used in Ubuntu 13.10 and earlier, here’s how to switch it back.

The new lockscreen, light-locker, is forked from gnome-screensaver that aims to have simple, sane, secure defaults and be well integrated with the desktop while not carrying any desktop-specific dependencies.

If you would like to try this lockscreen in Ubuntu 13.10 or Ubuntu 13.04, see this post.

To restore previous Lockscreen in Ubuntu 14.04:

UPDATE: The option has been removed in Ubuntu 14.04 final release. So this tutorial won’t work anymore.

Search for and install Compizconfig-Settings-Manager in Ubuntu Software Center. Or press Ctrl+Alt+T on keyboard to open the terminal, and run the command below instead:

sudo apt-get install compizconfig-settings-manager

After that, start CCSM from Unity Dash and navigate to Ubuntu Unity Plugin -> General -> Lockscreen. Click on the drop-down box and select which screen locker to use.

That’s it. Enjoy!
