XFCE is a more lightweight Desktop Environment (or Common Environment) and it will use less RAM and CPU, which are able to make my laptop battery life longer (about 8~12 hours for normal use).

XFCE is clean and easy to customize. You can install lots of plugins for XFCE and make it like Gnome or KDE but have less CPU use than Gnome and KDE. And it is cleaner as well.

# Install

Note. It is not necessary and recommended installing xorg independently looking forward to lightweight. Some packages from xorg group would install automatically as the dependent packages of XFCE

# pacman -S xfce4 to install XFCE. It is NOT recommended that you can # echo "exec startxfce4" >> /etc/X11/xinit/xinitrc to start xfce4 in the next boot and ignore step 3. It is highly recommended installing a display manager (DM) to start your system because DM will start your system more proper and create a user locker for log in as well.

# pacman -S lightdm lightdm-gtk-greeter light-locker to install this recommended lightweight DM, then # systemctl enable lightdm to let lightdm start automatically when you boot your system. You can also choose your DM. P.S. lightdm is the main DM, lightdm-gtk-greeter is for configuring your lightdm, light-loceker is for that you can lock your screen with your settings.
