+LightDM is a cross-desktop [[id:a6e49794-6de9-4bc1-b448-77e97600d3f3][login-manager]]. Its key features are:
+
+Cross-desktop - supports different desktop technologies.
+Supports different display technologies (X, Mir, Wayland ...).
+Lightweight - low memory usage and high performance.
+Supports guest sessions.
+Supports remote login (incoming - XDMCP, VNC, outgoing - XDMCP, PAM).
+Comprehensive test suite.
+Low code complexity.
+
+LightDM handles the autoligin feature on  Linux, which can be enabled in the lightdm conf file located in:
+#+begin_src  bash
+ /etc/lightdm/lightdm.conf
+#+end_src
+To enable this feature search for the autologin entry inside lightdm.conf and change it as follows:
+from
+#+begin_src bash
+  #autologin-guest=false
+#autologin-user=user
+#autologin-user-timeout=0
+#+end_src
+to
+#+begin_src  bash
+  autologin-guest=false
+autologin-user=<your_username>
+autologin-user-timeout=0
+#+end_src
+Because the config is located in the [[id:673d1cb1-536b-42f1-a046-40a8937c4283][root]] folder, you have have root priviliges to change the setting ([[id:dc54334e-afa9-4a53-be91-1e90bc6bf8d0][sudo]])
+Additionally the user has to be part of the autologin group.  To add the user to the group type the following command in the command line;
+#+begin_src  bash
+sudo groupadd -r autologin
+sudo gpasswd -a username autologin
+#+end_src
+the first command creates the group if the group does not exist yet.  The second command adds the user.
