Which Fedora spin did you use? There is a KDE Fedora Live CD that runs the same window manager as Kubuntu.
Whether they are configured alike is a different topic, but they can be, I guess.
Downloaded, then burned "Fedora-15-i686-Live-Desktop." I think it defaults to Gnome3 (?).
Didn't make any real changes - changes to live CD are current session only (as you know). Thanks ...
