Guide to logging in with the Sugar desktop

You may have installed Sugar on Debian/Ubuntu, Fedora, any other distribution by following the Sugar documentation or may have installed the Sugar Live Build on a Virtual Machine.

Each Linux distribution comes with a Display Manager.

A Display Manager (DM) is essentially a graphical login program, that
lets you switch users or switch desktop environments.

The most popular display managers are GDM, LightDM, and SDDM.

• GDM is used with the GNOME desktop environment on Debian, Ubuntu and Fedora.

• LightDM is used with Raspbian on Raspberry Pi.

• SDDM is used with KDE.

To log in with the Sugar Desktop, select Sugar at the login screen before logging in. Depending on the display manager, you may have to select a gear icon, wrench icon or a dropdown menu to do this.

Some examples are shown below:
