On startup I get a very crude (and huge) login screen that says, "Welcome to vector.1.net" and asks for the login and password. No user names or options are mentioned. This is the same as it has always been.
I selected System > KDM Setup.
The computer asks for the root password.
It then says, "What do you want to change?" and the options are "Enable autologin", "Disable autologin" and "Change login picture".
After selecting the enable autologin option, it asks, "Who should be logged in utomatically?" The options are "VL" and my friend's name.
I selected my friend's name, clicked the 'ok' button and the computer responds with, "Autologin configured for user name
However, doing the above doesn't change anything.
