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.  However, one must open the lid or put the laptop already resumed onto the dock in order to get the external monitor to be detected.  After that, closing the lid results in putting the external monitor into stand-by mode.  To get around this, each time, one must bring up the control panel->devices->displays and manually select single display or toggle it if a single display is already selected. 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 with Gnome 3.26 generally, but this situation is annoying.
