Public bug reported:

1. Install ubuntu-desktop-16.04-amd64
2. sudo apt-get update && sudo apt-get install unity8-desktop-session-mir
3. Reboot.
4. Log in to unity8 session.

Result: black screen, no mouse pointer. The screen backlight dims after
a while.

Reporting yet another new bug to try to get apport to attach useful
logs.

Workarounds which don't help:

* Moving the mouse for 20 seconds to generate entropy before logging in.
* Deleting ~/.cache
* Switching to/from ttys.

On checking ps waxf I can see that a large number of unity related
programs are running, including unity8 and unity8-dash (see attachment)
but nothing is rendered.

My system is an N455 Atom with Pineview graphics, which should use the
intel driver. Unity 7 works fine.
