Cinnamon: Pas d'icône ni de menu contextuel

Debian stretch 9.8:
installation poste de travail avec cinnamon comme bureau par defaut.

-> pas d’icône ni quoi que se soit en fond d’ecran, mis a par l’image debian par defaut et la barre de menu en bas ( déjà pas mal). Les changements d’images ne sont pas pris en compte sauf dans le menu contextuel du gestionnaire de fichier.

-> log:
