Правильные мониторы не обнаружены на 16.04 Nvidia или Nouveau

После установки 16.04 Dell 2408WFP не был обнаружен драйвером Nouveau по умолчанию. Затем я установил реальный драйвер Nvidia, надеясь на другой результат, но это дало тот же результат.

Теперь я снова сменил мониторы, и они все еще не отображаются. Эти мониторы отображаются только как CRT-0 на панели управления NVIDIA X Server Settings.

Есть какие-нибудь идеи относительно того, что я могу сделать, чтобы заставить драйверы X и Nvidia правильно определить подключенный монитор?

Вот копия моего журнала Xorg.0.log для обзора .

Когда я изменяю xorg.conf следующим образом:

я, к сожалению, получаю следующую ошибку:
