Hi same problem here.

Installed following steps described https://wiki.ubuntu.com/Touch/Libertine via ssh

Logfiles in ~/.cache/upstart/ from Desktop Apps all with same error :

(EE) ^M
Fatal server error:^M
(EE) Failed to connect to Mir: Failed to connect: not accepted by server^M
(EE) ^M
(EE) ^M

any idea?

Thanks in advance
