Public bug reported:
If a platform is too old or unsupported Mir starts but unity8 crashes
(bug 1304959) The result is a black screen with a mouse pointer.
Instead, at least a warning should be displayed or better, fallback to a
supported lightweight session (like it was with Unity-GL -> Unity-2D)
Test Case:
1. Install Trusty on a machine that is not capable of running Mir + Unity8
2. Install unity8-desktop-session-mir
3. In lightdm select the session 'unity8-mir'
4. Login
Actual behavior:
A black screen with a mouse pointer and a unity8 crash (bug 1304959)
Expected behavior:
Detect if the platform is supported and start a fallback session if it is not.
