=====Autologin=====

// Tested on Alpine Linux 3.21. //

  - Archive a copy of the lightdm.conf:<code>cp /etc/lightdm/lightdm.conf /etc/lightdm/lightdm.conf.original</code>
  - Open /etc/lightdm/lightdm.conf in vi:<code>vi /etc/lightdm/lightdm.conf</code>
  - Locate the line:<code>[Seat:*]</code>
  - BELOW that line add:<code>autologin-user=USER</code>
  - Replace "USER" with the login name of the account that should automatically logon.
  - Restart the computer. It should now automatically logon with the configured user.
