LXDE is a free and open source desktop environment for Unix and other POSIX compliant platforms, such as Linux or BSD. The name LXDE stands for "Lightweight X11 Desktop Environment". LXDE is designed to work well with computers on the low end of the performance spectrum such as older resource-constrained machines, new generation netbooks, and other small computers. Testing has shown that LXDE has a small energy-efficiency advantage over other desktops, and consumes considerably less memory under certain typical workloads.
