LXDE is a lightweight desktop environment for Unix and Unix-like operating system, such as BSD and Linux. It is designed to consume fewer system resources than other desktop environments such as GNOME.
LXDE's popularity has grown steadily since its first release, and it is now the default desktop environment of several Linux distributions, including Lubuntu, Knoppix, and Raspbian. Tests have shown that it requires about half as much RAM as comparable operating systems. It also consumes less power, making it a good choice for laptop users who want to maximize the life of their battery.
