[newbie] Xfce and KDE?

[WallerRaknakce]

Dear Paul and All, Thank you Paul for the explicit directions for setting up 
Xfce. How would I set up Xfce as one of my desktops and not to be the only 
one? Actually I want to use KDE and Xfce. In other words I want to be able to 
switch from one to the other.Those so far are my favorites. Any help will be 
appreciated. Thank you. Sincerely, Marcia
