  • Username tooltip tweaks
  • Language applet now displays country code labels
  • Login windows can no longer be positioned ‘off screen’

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run below commands one by one:

sudo add-apt-repository ppa:lightdm-gtk-greeter-team/stable

sudo apt-get update

sudo apt-get install lightdm-gtk-greeter

This will install the latest package for Ubuntu 14.04, Ubuntu 13.10, Ubuntu 13.10, Ubuntu 12.10 and their derivatives.

If you don’t like Launchpad PPAs, download & install the .deb from this page.


After installation, your login screen should changed at next boot. If not, edit the config file via:

sudo gedit /etc/lightdm/lightdm.conf

Make sure its content looks like:


Edit the /etc/lightdm/lightdm-gtk-greeter.conf file via below command to change the theme, icon, etc.
