[xubuntu-users] Repos

[miscemailstuff at gmail.com]

Sometime back when messing with the settings I came across an option 
which permitted a KDE desktop or a metalcity (????) gnome desktop and I 
think an Xfce desktop. Any idea what this control is as I can't seem to 
locate it since?

Is it possible to use Xfce oriented programs exclusively and get rid off 
kde and gnome items?

Thanks & Regards
