Moniteurs corrects non détectés sous 16.04 Nvidia ou Nouveau

Lors de l'installation de 16.04, un pilote Dell 2408WFP n'a pas été détecté par le pilote Nouveau par défaut. J'ai ensuite installé le pilote Nvidia dans l'espoir d'obtenir un résultat différent, mais le même résultat a été obtenu.

J'ai à nouveau changé de moniteur, et il ne s'affiche toujours pas. Ces moniteurs ne s'affichent que sous la forme CRT-0 dans le panneau de configuration NVIDIA X Server Settings.

Des idées sur ce que je peux faire pour forcer X et les pilotes Nvidia à détecter le moniteur connecté?

Voici une copie de mon Xorg.0.log pour examen.

Quand je modifie xorg.conf avec ce qui suit:

J'ai malheureusement l'erreur suivante:

J'ai pu résoudre ce problème en configurant manuellement mon propre /etc/X11/xorg.conf:
