The company behind the popular Linux-based operating system for desktops, servers, cloud, and IoT (Internet of Things) revealed last month its plans to replace the eye-candy LightDM login manager, which it used until now on numerous Ubuntu releases by default, with GNOME’s GDM (GNOME Display Manager). The first major change of the Unity 7 to GNOME Shell transition came in early June when Canonical replaced the Unity 7 session with the GNOME desktop environment by default in the latest daily builds, which now also ship with GDM as default login manager instead of LightDM.
