Public bug reported:
In the default configuration, resuming my T440s on the Lenovo ultradock
results in not detecting the external monitor followed by a suspend.
If I open the lid while on the dock, gnome detects the external monitor
and blanks the laptop display. Then, closing the lid results in
suspend.
As a work around, using tweak tool (or UPower) to ignore the lid, does
prevent the suspend. But it is not automatic; each time, one must bring
up the gnome control panel->devices->displays and manually select single
display. Then the lid may be closed without suspend.
This worked fine in 17.04, so I'm hoping that the provides enough clues
that this can be fixed easily.
Thanks! I am enjoying the new Ubuntu 17.10 generally, but this
situation is annoying.

I'm trying a kernel from mainline, just to see if that matters; it
doesn't. Same behavior on stock 17.10 kernel.
