How to get rid of desktop icons in Saucy

[Jim Byrnes]

This morning when I booted up my laptop the Computer, Home and Trash 
icons appeared on the desktop, they were not there when I showdown.

Googling has led to some old instructions that no longer apply.  I have 
installed Ubuntu-Tweak and dconfEditor.  I looked through all their 
settings and when the icons are mentioned they are either unchecked or off.

Is there any way to get rid of them?

Thanks,  Jim
