Make your Mouse Cursor Theme and Size Consistent - Even with Compiz and/or Emerald

I have to redact myself slightly, I was incorrect;

sudo mkdir /usr/share/icons/x-cursor-theme
sudo ln -s /etc/alternatives/x-cursor-theme /usr/share/icons/x-cursor-theme/index.theme

That would make the x-cursor-theme entry in dconf-editor work.
