Whether you want an information kiosk, digital signage display, in-car entertainment stack, or home automation interface, Mir on Ubuntu is your fastest path to deployment. Mir is a system-level component that can be used to unlock next-generation user experiences. It runs on a range of Linux powered devices including traditional desktops, IoT and embedded products. Mir is a replacement for the X window server system, commonly used on Linux desktop devices. It allows device makers and desktop users to have a well-defined, efficient, flexible, and secure platform for their graphical environment. Historically, graphical user interfaces Linux have been powered by the X windowing system. X has a long and successful history and it has served the purposes of both system level and application level UI well for more than 3 decades. However, users nowadays expect a more consistent, integrated and secure user experience than is possible to offer on top of the X windowing system.
