You're quite right. I shouldn't have assumed there is a guilty party.

I guess if I ever want to try Unity, I'll now know where to find it :)

Understood. I guess it could be automated - the DM knows when it has no
active sessions and could be told to restart when that next occurred -
but I can quite see that could easily be a step too far. Which throws
the problem back at the documentation, so poor punters like me would
know what needed to be done ... I see lightdm documentation is already
an entertaining subject.
