Public bug reported:

I noticed that after mako's version 213 of ubuntu touch
(http://people.canonical.com/~ogra/touch-image-stats/213.changes), the
display started failing quite frequently when using it with krillin (rtm
is fine though).

Tracking down the changes, it seems that the lightdm update from
1.11.6-0ubuntu1 to 1.11.7-0ubuntu1 is the one causing the issue, as I
can get my display to work perfectly fine with latest image + lightdm
1.11.6-0ubuntu1

The symptom is a bit weird though, as the display itself is on (with
proper brightness and so on), but nothing showing up on the screen (like
not being rendered for some reason). Display power off/on doesn't help,
and it seems Unity8 is running fine in the background.

When I get this issue, I'm also not able to see the ubuntu touch spinner
before Unity8 is up.

One way to get a working display again is by restarting ligthdm by hand.
