Make Ubuntu Login Screen a Browser, Using the lightdm-webkit-greeter

Hi all,
    This is a small and simple post for Ubuntu users, Those who hates the default Ubuntu login screen and wish to change it. Not a little change, we can make it a browser, that shows a webpage as login screen, so that we can easily design a login screen or use an html login screen available on web.
    Ubuntu’s default login screen is ‘unity-greeter’. This is a part of ‘lightdm’, the display manager of Ubuntu. So we are achieving this replacement by browser, by just replacing the ‘unity greeter’ with the ‘lightdm-webkit-greeter’. By the following steps:

Changing the theme
  1. Install ‘lightdm-webkit-greeter :By just executing:
    sudo apt-get install lightdm-webkit-greeter
  2. Replace ‘unity-greeter’ with ‘lightdm-webkit-greeter’ Navigate to /usr/share/lightdm/lightdm.conf.d/ there you will find some configuration files of lightdm. open ‘50-unity-greeter.conf’, and change ‘unity-greeter’ to ‘lightdm-webkit-greeter’. Now we are done! We are now replaced login screen with desktop. Now all we need is a beautiful theme, that makes our login screen beautiful..
  3. Change the themeHere is a sample theme for your Ubuntu login screen: Antergos Theme
    Download and extract it. Rename it to ‘antergos’ or some simple name.Then navigate to /etc/lightdm/ and open the file ‘lightdm-webkit-greeter.conf’. Edit the ‘webkit-theme’ to ‘antergos’ or give the foldername you have renamed.Antergos theme works well when antergos-wallpapers installed. Download the wallpapers from antergos-wallpapers and extract the images folder to /usr/share/.   
  4. Restart.

    The authentication is now done by the javascript bridge object called 'lighdm'. You can simply modify the theme by just editing the html files, or just try creating a new one!
    Hope that helped. Comment your doubts. Have a nice day!

Another way is using ISM, but it costs around $225 I think. Don't worry, here is a free and easy solution, use my FontConverter software. How to use it? It is so simple...
