Linux is a Unix-like computer operating system, first released in October 1991 by Linus Torvalds. The defining component of Linux is the Linux kernel, which forms the basis for many Linux variants, such as Ubuntu. It is assembled under the model of free and open source software development and distribution.
It has been ported to many computer hardware platforms (more than any other operating system). It is used heavily on servers, mainframes, supercomputers and other large computers. The 10 fastest supercomputers in the world run a Linux variant, as do 90% of the top 500.
Linux also runs on embedded systems such as mobile phones, tablet computers, network routers, building automation controls, televisions and game consoles.
Questions should use this tag when the question is specifically asking about a Linux version of a game, configuration or other technical support issues (specifically relating to Linux), or other gaming-related topics related to Linux.
