    Phoronix: Unity 8 + Mir Can Now Be Tried On The Ubuntu 14.04 Desktop

    As of today it's become more easily possible to try out the experimental Unity 8 desktop interface (compared to the Unity 8 mobile version for the phone/tablet) and powered by the Mir Display Server when running the latest Ubuntu 14.04 packages...

    I'm going to be one of those idiots that installs 14.10 the day it comes out, fully aware that some system breakage is expected. I'm really excited about Mir and Unity 8.

      Does Unity8 on Mir work with nouveau.

      I recall the test version of Gnome on Wayland worked on Intel, but not on nouveau.

        In general it should work. If it actually works, depends on the GPU and how well Nouveau supports that.

            if you dont see the difference im willing to bt you installed the qml shell not the actual unity8...
            i havent figured out how to install it either so dont worry.

            to lauch unity8 qml shell open the terminal and write unity8

              Wayland

              I would rather see Wayland.

              Unfortunately the Wayland and Weston in the Ubuntu repository is a bit dated now.

                top might help
                I remember from older videos that there should be a process called unity-session-compositor or something like that.

                  First of all the packages are for now in Trusty proposed. Later they will move to universe. There are two packages one for session running on:

                  X11 unity8-desktop-session-x11

                  Mir unity8-desktop-session-mir

                  When you have it installed the new session will be available to choose from login screen.

                  There is a possibility that you will have to do the same thing that is advised in the PPA for Unity8 desktop session.

                  NOTE: You may need to undo the damage done when libhybris was installed by running the command

                  sudo update-alternatives --config x86_64-linux-gnu_egl_conf

                  and choosing the non-libhybris alternative. The symptom that you need to do this is an error in /var/log/lightdm/unity-system-compositor.log that says something like this:

                  undefined symbol: _glapi_tls_Dispatch
                  The last time that I've read about this on blog of Stephen M. Webb from Canonical there was no mouse and trackpad support and keyboard input had no effect.

                  Right now you could just install this from a PPA and go at it, but there are some big wrinkles that still need to be worked out. For instance, thereís no cursor support so mouse and trackpad support is a little troublesome (works swell with a touchscreen), and keyboard input seems to have no effect ó Unity8 has been developed with phones and tablets in mind, they donít generally have a mouse, trackpad, or keyboard. Itís OK, there are plans in the works to add those, and thatís one of the reasons we have this session at this point in the Ubuntu release cycle.

                  Also, there is no way to log off from Unity8 (phones and tablets donít generally support that concept) so that pretty much requires a reboot of the whole system unless you have an SSH session open.
                  Like he writes Unity8 for now is developed for phones and tablets. Of course that shouldn't stop anyone from tinkering (myself included).

                          Did you check this:

                          NOTE: You may need to undo the damage done when libhybris was installed by running the command

                          sudo update-alternatives --config x86_64-linux-gnu_egl_conf

                          and choosing the non-libhybris alternative. The symptom that you need to do this is an error in /var/log/lightdm/unity-system-compositor.log that says something like this:

                          undefined symbol: _glapi_tls_Dispatch
                          Also if I remember correctly there are some problems with current Mir on desktops which should be resolved in next version 0.1.6.

                            The keyboard works fine, although there are no keyboard shortcuts (yet). The mouse/trackpad support is still missing because for some reason the cursor is not enabled in the display server, although certain multi-touch gestures work with trackpads. One of the reasons for landing this earlier in the Trusty Tahr release cycle is so developers can find and fix such issues that occur only in the desktop environment.

                              Installing the unity8-desktop-session-mir package should be all you need to do; it pulls in all the required dependencies.

                              There are a couple of bugs, one in Mir and one in QtUbuntu, that can cause Unity8 to fail to start. Fixes for these are working their way through the system. You will see errors in the file ~/.cache/upstart/unity8.log.

                              You may also run into trouble if you're using the proprietary drivers for your video card.
