Since I use Ubuntu 16.04 with Unity, I should be using Mir, which is the Ubuntu competitor to Wayland.
One of those things that you really can't understand why they sink money into it :(
You're wrong. That's Unity 8. And it's not the default DE (although you can apt-get install it).
I was looking forward to trying it out, because the Intel integrated graphics (HD4000) has bad tearing problems with application such as Firefox.
That, combined with PulseAudio problems may force me to re-install 14.04. Though I need to keep using Win10 this week because of a CAD program anyway.
