+===== Install a display manager =====
+A Display Manager is responsible for starting the display server and loading the desktop while managing user sessions and authentication.
+By default, GNOME Desktop uses GDM3 as its display manager, but it is a bit heavy on the resources side.
+==== Install ====
+A lighter and more resource-friendly display manager can be used.
+<code bash>
+sudo apt install lightdm
+</code>
+==== Start ====
+Start the display manager and load the GUI with the following command:
+<code bash>
+sudo service lightdm start
+</code>
+==== To check what display manager is configured in your system ====
+<code bash>
+cat /etc/X11/default-display-manager
+</code>
+returns:
+<code bash>
+/usr/bin/lightdm
+</code>
+==== To shutdown the GUI ====
+<code bash>
+sudo service lightdm stop
+</code>
