Xfce is a lightweight desktop environment for UNIX-like operating systems. To install Xfce 4, use following port `xfce4 4.8`, its a meta-port for installing Xfce

cd /usr/ports/x11-wm/xfce4/
make install clean

LXDE, the 'Lightweight X11 Desktop Environment' is said to be one of the small, extremely fast-performing and energy-saving desktop environment.
to install LXDE use metaport `lxde-meta`

cd /usr/ports/x11/lxde-meta/
