Lubuntu (short for Light Ubuntu) is a GNU/Linux computer operating system designed especially for low-performance hardware. Older and cheaper than average computers tend to struggle with many of the newer, fancier systems due to the high resource requirements of these systems. Lubuntu offers a small, efficient system for these computers which enables users to work as effectively as possible on their old or inexpensive hardware.
This operating system needs at least a Pentium 4, Pentium M, or AMD K8 processor to function well. Lesser processors may work, but using certain internet services and programs may be difficult.
