No virtual desktop config in System Settings->Desktop Behavior

[David L]

Hi,

I am running Ubuntu 16.10 (64 bit) with KDE (I first installed Ubuntu
and then the KDE environment due to some installation problem with the
kubuntu iso).  When I open the Desktop Behavior entry under System
Settings, I don't have an option to configure Virtual Desktops from my
user account that I have been using under 16.04 and older.  From a new
user account, I do have the Virtual Desktop option, but I'd like to be
able to retain my KDE panel settings from my old account and be able
to configure user desktops.

My options under System Settings->Workspace are:
Workspace
Desktop Effects
Screen Edges
Screen Locking
Accessibility
Activities

Any idea why the Virtual Desktop config is missing?

Thanks,

     David
