I just did a clean install using the Plasma desktop, and I selected to encrypt the drive and automatically login to my account. After the install was done and it had rebooted, I typed in the password to access the parition and boot into the system. Instead of logging in automatically I was greeted with the login screen set to Elarun theme, and it did not automatically login.
In addition, is it possible to have the default theme of SDDM set to Breeze instead? Perhapes that’s why the auto login didn’t work?
