Running Mir on phablet

[Daniel van Vugt]

Kevin, anyone,

I notice running Mir on the latest phablet images (Nexus 4) is still not 
foolproof. Half the time, when I stop Unity8, that completely blanks the 
screen which prevents any Mir server from starting.

Mir can only start, it seems, if the screen is not fully blanked. If it 
is blanked then I get permission errors (failed to unblank display), 
even running as root.

What's the trick/recommended approach? It seems my old tricks don't work 
any more now the phablet images are "flipped".
