Userful Multiplier is a multiseat Linux desktop virtualization solution that enables a single computer to support up to 10 independent users at the same time, each with their own monitor, keyboard, and mouse by using extra video cards and virtualizing the X server. This approach offers the features of a full PC including high performance video and significantly reduces hardware costs, support and maintenance costs, electricity consumption, and e-waste as compared to stand alone PCs or thin clients. It installs on most popular Linux distributions, supports per-seat USB and 2-way audio, and works with virtually all video cards supported by X.
