Hello Linux Geeksters. As you may know, LightDM is a lightweight display manager used by default on Lubutnu, Xubuntu and Kubuntu.
The latest version available is LightDM GTK+ Greeter 1.7.0, which has been recently released. Among others, it comes with support for displaying avatars, a better looking graphical interface, a bunch of new keyboard shortcuts, enabling the users to access different menus via the F1, F2, F3 and the arrow keys.
In this article I will show you how to install LightDM GTK+ Greeter 1.7.0 on Ubuntu 13.10 Saucy Salamander, Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal, Linux Mint 16 Petra, Linux Mint 15 Olivia and Linux Mint 14 Nadia.
Because it is available via repository, installing LightDM GTK+ Greeter 1.7.0 on the listed Ubuntu and Linux Mint systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the lightdm-gtk-greeter. Like this:
$ sudo add-apt-repository ppa:lightdm-gtk-greeter-team/stable
$ sudo apt-get update
$ sudo apt-get install lightdm-gtk-greeter
After the installation has been successfully done, choose LightDM as the default display manager, from the graphical user interface.
