Hello Linux Geeksters. As you may know, LightDM is a lightweight display manager used by default on Lubuntu, Xubuntu and Kubuntu, responsable for the login screen, the management of the X servers and facilitates remote logins via the XDMCP protocol.
The latest version available is LightDM GTK+ 1.8.4, which has been recently released, coming with important fixes. Among others, the “show-language-selector” setting has been deprecated, the screen timeout can be configured if used as a lock screen, the “show-indicators” setting enables the users to control all the indicators, when shutdown or reboot is performed, the user will be noticed if there are any other logged in users, the theming support has been enhanced, a bunch of keyboard shortcuts have been implemented and the PAM messages have been improved. For more information, see the release notes.
