Are you trying to clean the trash folder but some files/folders still remain in place ? This can happen if these files/folders belong to another user and you don't have the appropriate permissions. Ok, the solution is to open a terminal and  use "sudo rm" in the trash folder.  But where is the trash folder?

In previous versions of Ubuntu Linux, the folder was  ~/.Trash and you could write

sudo rm -r ~/.Trash/*

In Ubuntu Intrepid Ibex the folder has changed position. Now you must write

sudo rm -r ~/.local/share/Trash/*
