Upon installation of 16.04, a Dell 2408WFP was not detected by the default Nouveau driver. I then installed the actual Nvidia driver hoping for a different result, but that yielded the same result.

I've now changed monitors again, and it is still not showing up. These monitors only show up as CRT-0 in the NVIDIA X Server Settings control panel.

Any ideas as to what I can do to force X and the Nvidia drivers to detect the proper monitor that's attached?

Here's a copy of my Xorg.0.log for review.

When I modify xorg.conf with the following:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/psaux"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Keyboard0"
    Driver         "kbd"
EndSection

    Identifier     "Monitor0"

    ModelName      "Unknown"

    VertRefresh     43.0 - 72.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Viewport   0 0
        Depth     24
        Modes "1366x768"
    EndSubSection
EndSection

I unfortunately get the following error:

Could not apply the stored configuration for monitors

none of the selected modes were compatible with the possible modes:

I was able to resolve this by manually setting up my own /etc/X11/xorg.conf:
