Somehow my Mate desktop got corrupted. It initially had only the home and trash folders. Now it shows all the files and folders in my /home/username folder. If I go into MATE Tweak and uncheck "Show Desktop Icons", all the files and folders disappear. This is not exactly what I want. I would like for my desktop to only show the items I have checked in MATE Tweak.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial
MATE 1.12.1
Any suggestions on how to restore the default configuraiton?
