How to disable right-click on the desktop in Xfce 4.10

This is the second shoot on Xfce.

First my testing box:

  Fresh Install 12.04 32-bit.
  Then apt-get update, upgrade and dist-upgrade
  Then ppa upgrade xfce4 4.10
  Reboot.

Try the following:

1. In Settings > Desktop > Menus
 a. uncheck Show applications on right click.
 b. uncheckShow window list on middle click.

2. go to Settings > Desktop > Icons
 select type: None or Minimized

Then this should pretty much disable all interaction with the desktop.

To apply this change system wide, copy changes from your user folder to:

/etc/xdg/xdg-xubuntu/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml
