LightDM GTK+ Greeter Settings is a small GUI written in Python which lets you modify various LightDM GTK+ Greeter settings, such as the theme, font, background, window position and more, settings which otherwise can only be set by modifying the greeter configuration files.

The tool was supposed to be added by default in Xubuntu 14.10 Utopic Unicorn but it was postponed, most probably because LightDM GTK+ Greeter Settings is not yet available in the official Ubuntu repositories (though a bug for this was submitted back in March, 2014). Hopefully, it will make it in Xubuntu with the release after Utopic - 15.04.

LightDM GTK+ Greeter Settings gives users access to the following settings:
  • Appearance: change LightDM GTK+ Greeter theme, icons, font (with DPI/antialias/subpixel rendering and hinting settings), change the background image or set it to a color, enable user wallpaper if available or change the default user image;
  • Panel: change the clock format and redefine indicators (enable/disable indicators or reorder them);
  • Window position: change the login dialog window position
  • Misc: enable/disable onscreen keyboard, set the timeout until the screen blanks.
