desktop environment,    making  KDE one of  the most    closely integrated  and
consistent  Linux   desktops    available.

Xfce and Xubuntu
Xfce    is  a   lighter desktop environment that    requires    less    memory  and
processing  power   than    either  GNOME   or  KDE and is  therefore   often
suggested   for use on  older   machines.   It  does    not deserve to  be  relegated   to
that    role    because it  also    works   great   on  current hardware    and is  often   a   quality
choice  for a   different   reason. Xfce    has been    developed   using   the traditional
UNIX    philosophy  of  software:   Do  one thing,  do  it  well,   and play    well    with
others.
The parts   of  the Xfce    desktop environment are modular;    you can add or
remove  bits    at  will    and substitute  other   programs    that    perform the same
function.   Everything  created by  or  included    in  Xfce    is  expected    to  work
according   to  simple  standards   that    allow   other   programs    to  interact    with    it
easily.
On  one hand,   this    sometimes   means   that    people  look    at  Xfce    and think   it  isn’t
as  seamlessly  integrated  and smooth  as  the two main    desktop environments.
