LightDM GTK+ Greeter brings a quick, reliable, and GTK+ 2/3 support login screen. It is used by a number of Ubuntu’s flavours, including Xubuntu.

The latest version 1.7.1 has been released a few hours ago with below changes:

  • Username tooltip tweaks
  • Language applet now displays country code labels
  • Login windows can no longer be positioned ‘off screen’
  • Improvements to handling of xscreensaver timeout
  • Login button set as “default” widget

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.

sudo gedit /etc/lightdm/lightdm-gtk-greeter.conf

In below config file I used the Numix gtk theme:

# background = Background file to use, either an image path or a color (e.g. #772953)
# theme-name = GTK+ theme to use
# icon-theme-name = Icon theme to use
# font-name = Font to use
# xft-antialias = Whether to antialias Xft fonts (true or false)
# xft-dpi = Resolution for Xft in dots per inch (e.g. 96)
# xft-hintstyle = What degree of hinting to use (none, slight, medium, or full)
# xft-rgba = Type of subpixel antialiasing (none, rgb, bgr, vrgb or vbgr)
# show-language-selector (true or false)
# show-indicators = semi-colon “;” separated list of allowed indicator modules (e.g.
# show-clock (true or false)
# clock-format = strftime-format string, e.g. %H:%M
# keyboard = command to launch on-screen keyboard
default-user-image = /usr/share/pixmaps/griffon_icon.png
font-name=Ubuntu 11
