Yes, I saw that code. There should be no reason for it to detect in
external monitor, however that doesn't mean it isn't getting it wrong.

I notice there is a number log_debug(...) messages scattered through the
code that I thought might help, however I don't think these are getting
logged anywhere - however I am also looking at the latest git version, and
I amu running systemd from Jessie...

They get a message "Ignoring lid switch request, 4 displays connected." - I
am not seeing this. Also first suspend after reboot usually encounters this
issue. So not convinced this is it :-(

Then again, maybe I was premature; I think I should do a reboot and redo
the following:

[brian:~] % for i in /sys/class/drm/*/*/status ; do echo $i ; done
