    When I installed the unity8-desktop-session-mir in daily live image of Trusty and run the update-alternatives command libhybris was default.

    Unity8 session on Mir didn't work for me I ended up with black screen. Most likely it was the Mir bug.

      Try adding the PPA found at https://launchpad.net/~unity8-deskto...archive/custom to your sources. It has up-to-date Mir and QtUbuntu packages containing the bug fixes.

        I think that in it's current state, that's not in their best interests - anyone who needs a simple installer shouldn't be using it yet...

          ok... it is indeed very easy to install simply install the unity8-desktop-session-x11 or -mir package and off you go. the only thing that held me off is that i couldnt find to switch sessions on the login screen. (clicking on the ubuntu logo next to the username...)
          however the mir version delivers a black screen and the x11 version is hardly usable and not really for dekstop but an android simulation (looks like one: small vertical screen and scrolling through unity scopes left and right when you manage to click the left menu on the clock screen)
          to go back just switch to console and type "unity" to get your desktop and change session back.

              Mir is currently supported only on free drivers, so your best results will be obtained using Intel video. If you're using a recent Ubuntu (eg. 14.04 LTS or the Utopic Unicorn development series), just install the unity8-desktop-session-mir package from the archives, then choose the Unity 8 session at the Lightdm login screen.

              Running Unity 8 on anything other than Mir is not officially supported. It works when run on an X11 desktop for now, but there is no guarantee that will continue into the future.

                  1. You may have a messed-up libhybris installation -- libhybris is a package that emulates libc on an Android system and has no business being on the desktop, and it does evil things by redirecting your EGL implementation to its own, which fails miserably without the rest of the Android runtime in place. See the comment here on how to undo that.
                  2. A transient bug in the Utopic Unicorn series (14.10 prealpha) also causes a similar symptom. A fix is pending, or you can revert to a the previous version of the unity-system-compositor package. The trick with pre-alpha is sometimes things break.
                  If fixing one or both of those known problems doesn't get you up and running, you should really open a bug against the unity8-desktop-session project.

                    as of today it seems to be "working" (on nouveau): means it shows a desktop but input seems to be bugged for now. the libhybris is not being used so no need for update-alternatives.
                    i have installed ubuntu-desktop-next on 14.10 dev though (it installs more packages)
