Autologin in Mate
When you start your Korora system it takes you to the LightDM so you can enter your password and start Xfce. However if you are the only user of the system you may prefer to bypass this screen and have Korora go straight to the desktop.
As Mate uses LightDM as the default Display Manager see https://kororaproject.org/support/documentation/autologin-in-lightdm to configure Autologin. Please note the additional section specific to Mate at the end of that guide.
