Install LXDE in Ubuntu

February 13, 2010

Last week I decided to try LXDE (Lightweight X11 Desktop Environment) on my Karmic Koala. Here is the overview & how to install LXDE on Ubuntu.

The "Lightweight X11 Desktop Environment" is an extremely fast-performing and energy-saving desktop environment.
Why use LXDE?
LXDE uses less CPU and less RAM than other environments. It is especially designed for cloud computers with low hardware specifications, such as, netbooks, mobile devices (e.g. MIDs) or older computers. Here is System Monitor comparison during my test:

  • Open Terminal & paste these lines [karmic]:

How to use LXDE session?
  • After successful installation logout your gnome session.
