[newbies] Создать подменю Applications/Science, не работает для XFCE

[Константин Яблочкин]

В brlcad ( http://git.altlinux.org/people/yakonstb/packages/?p=brlcad.git;a=summary ) кладу файлы .desktop, .directory, .menu в папки
/usr/share/applications
/usr/share/desktop-directories
/etc/xdg/menus/applications-merged

В Mate появляется подменю BRL-CAD в меню Science. И все кнопки идут туда и во вложенное туда подменю
В XFCE все кнопки лежат в меню Other
