Lost my virtual desktop

[A.J. Bonnema]

Hi all,

I run fedora 20 fully updated (on x64). I just renamed my .kde and 
.kdevduchain to respectively .kde-old and .kde-vduchain-old. My goal was 
to get the default desktop, and I did. However, in the process I lost my 
virtual desktops. I find life in KDE pretty hard without my virtual 
desktops.

I can't for the life of me find how to re instate the virtual desktops.

P.S. If any one knows what the vduchain is for, I would like to know 
that too. But it's no biggie.

Can anyone help me get my virtual desktops back?

Kind regards, Guus.
