How to get Pantheon Greeter on Ubuntu 14.04 instead of Unity Greeter

I'm running Ubuntu 14.04, how can I replace the lockscreen with the one on Elementary Luna (Pantheon-Greeter). Thank You!!

Edit: Can anyone do it and confirm it works completely?


Solution 1:

To install Pantheon Greeter on Ubuntu 14.04,Open terminal and run the commands:

Since libgranite3 (>= 0.2.0) missing in 14.04,so we need the following PPA as well.

sudo add-apt-repository ppa:elementary-os/os-patches  
sudo add-apt-repository ppa:elementary-os/daily
sudo apt-get update 
sudo apt-get install pantheon-greeter

Note:
After installation remove ppa's:

sudo add-apt-repository -r ppa:elementary-os/os-patches
sudo add-apt-repository -r ppa:elementary-os/stable
sudo apt-get update

Note: Tested and working. refer here
