Logon screen layout change from KDE style to Gnome style
Without reinstalling Fedora, what is it that I must do to change the greeter/login screen from the single line with password, to the clickable user list-name and password?
See this page for configuring KDM - http://docs.kde.org/stable/en/kde-workspace/kdm/configuring-kdm.html
As far as I know, KDM can be configured to show user list. In the above linked page, click on users and it shows how to enable this.
Hope this helps.
