The default desktop has three primary icons -- Home, File System and Trash -- as well as icons for partitions and removable devices, if they are present. Additional files, folders, application launchers and website shortcuts can be added to the desktop and can be manually or automatically arranged. You can set the desktop wallpaper and which desktop icons are visible, as well as their options, by right-clicking in a blank area of the desktop and choosing Desktop Settings from the context menu.
