I want to change my default login from KDE to XFCE. I have specified autologin in Yast -> users but I can’t see where to set the default session.
Logout of KDE. In the login screen, click Sessions. just once pick XFCE and login. The login manager remembers your choice. On a reboot, even with autologin enabled, you will be logged in on XFCE. That’s all. If there are multiple users, you’d have to do this for every user.
