hello, everybody, I encounted some problem when in the process of using nautilus . And I need some help, At first, Thanks for all who have read this mail. sincerely
==The discription of the problem is as follows:==
I think it will be convenient if  the "Arrange Items menu" on the popup menu(right click) of desktop will  be visible.
so I hacked the file "nautilus-2.16.0/src/file-manager/fm-icon-view.c" by commented the lines which set the menuitem to be invisible  when in auto-layout like this :
# if 0
        if (!fm_icon_view_supports_auto_layout (icon_view)) {
                action = "" (action_group,
                                                      FM_ACTION_ARRANGE_ITEMS);
                gtk_action_set_visible (action, FALSE);
        }
#endif

then I updated my nautilus , Unluckily, The menuitem "Arrange Items" got be visible, but  all the  menuitems doesn't act except the last two "Compact Layout"  and "Reversed Order" . 

==waiting for good news==
