display server release , which continues to be developed by Canonical, despite the abandonment of the development of the Unity shell and the Ubuntu edition for smartphones. Mir remains in demand in Canonical projects and is now positioned as a solution for embedded devices and the Internet of things (IoT). Mir can be used as a composite server for Wayland, which allows you to run any applications using Wayland (for example, built with GTK3/4, Qt5 or SDL2) in Mir-based environments. Installation packages prepared for Ubuntu 16.04/18.04/18.10/19.04 () and . Project Code licensed under GPLv2.
The new release optimizes the performance of Wayland-related code and adds a new graphical platform “wayland”, which allows you to run Mir as a client running another Wayland composite server (such a server can also be the miral-system-compositor provided in Mir) . Switching between different sessions is done via Ctrl-Alt-PgUp/Ctrl-Alt-PgDn. This feature was the last link needed to migrate the UBports/Ubuntu Touch stack from mirclient to Wayland and launch Unity8 as a unity-system-compositor client.
In addition, an initial implementation of the rpi-dispmanx graphics platform is available for Mir, intended for use on the Raspberry Pi. New demo applications included
mir_demo_client_wayland_egl_spinner and miral-system-compositor. Issues with building on Arch Linux have been resolved.
