dinamic, you are a star...
Unfortunately I can think of a few reasons why this might happen.
1. Unity8 server died (although you would have noticed)
2. Apparmour problems
3. Fullscreen apps may crash the server in Mir 0.26.0 (bug 1661508)
And worse, when I try to test supertux under Mir right now it fails for
a 4th reason:
$ mirrun /usr/games/supertux2
[FATAL] /build/supertux-LmXSob/supertux-0.5.1/src/supertux/main.cpp:510
Unexpected exception: Couldn't initialize SDL: Failed to connect to the mir
server: Failed to connect to server socket: No such file or directory
Which sounds like a known issue with non-root users not being able to
auto-discover the Mir socket path. However then running it as root also
fails (SDL crashes trying to use X11).
I can't tell where the cause of this bug is. Might also be in SDL.
