I recently installed xubuntu and wanted some good compositing. I tried compiz but it seems a bit buggy with xfce.
I recently found a great solution. Using elementary os's gala window manager. it works amazingly with xfce! incredibly smooth, stable, and fast. I'm also using plank as the dock and it all integrates very well, feels like I'm using eOS luna, but with all the mature stable xfce apps.
To install it on xubuntu just do the following:
Add the elementary daily ppa and install gala
sudo apt-add-repository ppa:elementary-os/daily
sudo apt-get update
sudo apt-get install gala dconf-tools
Set gala as xfce's default window manager
cp /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml
leafpad ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml
replace "xfwm4" with "gala"
Put min/max/close buttons on the right
open dconf-editor:
org pantheon desktop gala appearance
button-layout: :minimize,maximize,close

My current desktop, still got plenty of tweaking left to do. running great already though, blazingly fast and smooth: http://i.imgur.com/grZzR.png
