Installing Xfce on a machine running Unity 3D

[Jim Byrnes]

After trying Unity for awhile I just don't like it so I have been 
looking for a substitute.  I've seen people recommend  using Xfce  or 
running Xubuntu.  I ran Xubuntu in Virtual Box for awhile and like it. 
Before I wipe Unity from my laptop and installed Xubuntu I wanted to see 
what adding Xfce would do.  I had 11.10 running in Virtual Box so I 
installed the Xfce desktop in it.

One of the first things I noticed was the Unity style scrollbars were 
being used by apps running on the Xfce desktop.  Since this style of 
scrollbar  is one of the bigger annoyances I find in Unity it looks like 
a reinstall is the best way for me to proceed.

Is this normal behavior?  From what I read here I thought the two 
desktop systems were separate and distinct from each other.
