Bonjour,
J'utilise l'environnement de bureau Cinnamon sous Ubuntu tout en ayant aussi Unity et MATE installés (je peux sélectionner l'environnement de bureau depuis l'écran de démarrage).
Depuis la mise à jour vers zesty, j'ai perdu plusieurs fonctionnalités sous Cinnamon : les touches FN ne répondent plus (que cela soit pour le son ou la luminosité), l'applet brightness ne fonctionne plus non plus, idem pour le multi-écran. Sous Unity tout fonctionne corrrectement.
J'ai restauré les paramètres de Cinnamon à zéro sans succès.
Dans le log xsession-errors j'ai :

Il semble y avoir un conflit entre deux environnements de bureau. Mais désinstaller Unity et MATE n'a pas résolu le problème.
Merci d'avance pour celui/celle qui me donnera une piste !
