Mir 1.6.0 Release
We’re pleased to announce the release of Mir 1.6.0.
For Ubuntu, Mir is available from the Mir PPAs:
It is also available as a source tarball.
We’ve improved the diagnostics when starting a graphics platform fails and added some tooling to help with the development of new graphics platforms.
New “wayland” graphics platform
This enables Mir to run as a client of another Wayland compositor (which can also be Mir). To use this configure with
--wayland-host <wayland-socket> or equivalent.
miral-system-compositor miral-shell --wayland-host wayland-0 egmde-confined-desktop --wayland-host wayland-0
Switch between hosted sessions using Ctrl-Alt-PgUp/Ctrl-Alt-PgDn
This is the last building block needed to enable migrating the Ubuntu Touch stack from mirclient to Wayland. (This will allow Unity8 to run as a client of unity-system-compositor.)
Work in progress: “DispmanX” platform
@raof’s initial work on the dispmanx platform for Raspberry Pi has landed. There’s more work to be done in Mir, and it requires a specialized system image with the driver stack enabled to work but progress is being made.
There are some performance improvements and bugfixes.
It seems more package updates (GMock & Mesa IIRC) on Arch broke the build recently. That’s now fixed, hopefully also for any other distros that saw this problem.
