An Introduction to the LXDE Desktop
LXDE stands for the Lightweight X11 Desktop Environment - and is based on the standard X-Windows subsystem. Unlike Gnome and KDE, the main ethos behind LXDE, as it's name implies) is on low-resource usage, allowing it to run comfortably on old hardware (-for example, machines with Pentium II processors).
For this reason, all the big distributions - such as Ubuntu, Fedora and Mint all provide an LXDE alternative to their standard Gnome distributions, allowing you to standardize your favourite Linux across all your PCs.

One way of minimizing the resources used by LXDE is by avoiding the temptation of using sophisticated 3D graphics animations: in this way, LXDE can be seen as a perfectly functional desktop that is not overly showy, unlike some of it's rivals.
The LXDE minimal requirements (-as of 15th March 2012) are as follows:
- Processor: Pentium II or above
- Memory: 45Mb (running)
- Disc Space: 750Mb (running)
Of course, unless you are a Linux expert, you will normally download LXDE as part of a Linux Distro. Most of the major Linux Distros provide an LXDE alternative, including:
You can also download it as a package (-e.g. sudo apt-get install lxde) for an existing Linux installation.
If you have old (-but not ancient) or low-specification hardware, then, provided you can meet the minimum requirements above, then LXDE is an excellent desktop choice!
As long as you download the respective Gnome or KDE libraries first - and you have the resources to run them - you can run Gnome or KDE-based software under LXDE.
