LXDE Forums

A good starting point is the General Information page, where you find information on system requirements and compatibility. You also find an overview of distributions including LXDE with installation instructions

LXDE uses less RAM and less CPU while being a feature rich desktop environment. Unlike other tightly integrated desktops LXDE strives to be modular, so each component can be used independently with few dependencies. This makes porting LXDE to different distributions and platforms easier.
