Bug Description
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-
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.
| summary: |
- Provide a fallback or warning dialog if platform is too old or - unsupported + Start a fallback session if platform is too old or unsupported |

the problem here is there is no X (w/o mir) to fallback to, since Unity8 relies on Mir. What is really needed to get to a "fallback" is a Mir sw renderer (when no gl support is possible)
we've had this as an enhancement, but simply haven't had time to address.
