How Do you Autologin in Lubuntu 18.10?

Solution 1:

USE SDDM which comes standard in lubuntu 18.10

Had to edit /etc/sddm.conf

Here is an example sddm.conf:

[Autologin]
Relogin=false
User=christian
Session=Lubuntu

Solution 2:

go to Preferences -> KDE.System.Settings (in the menu)

In the Login Screen (SSDM) setting there is a checkbox for Auto Login. Ensure the check-box is clicked and your username should become easily readable.
