Help with monitor resolution - can't get 1680x1050

I use a laptop mostly, and its plugged into a monitor on my desk.  My laptops highest res is 1920x1200, but my desktop monitor is limited to 1680x1050.  I had used nvidia-settings to configure both monitors to be twinview a long while ago and everything was working great.  However, with the latest updates "something happened".

For some reason nvidia-settings is no longer finding 1680x1050 as a resolution for my laptops LCD, even though it had prior to the update.  I can't seem to get the Cloned TwinView running at 1680x1050 anymore.  I can either have them both on and have the bottom clipped from the desk monitor, or I can shut off the laptop LCD and have the other running at 1680x1050.   For now I did the latter, but I'd like to find a way to make it work like it had been for the past 2+ years.

Basically, I want to force xorg to recognize the resolution mode for the laptops LCD but I don't know how too.

For reference, my old xorg.conf screen section that worked prior to update.

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "DFP-0"
    Option         "metamodes" "CRT: nvidia-auto-select +0+0, DFP: 1680x1050 +0+0"
    Option         "RenderAccel" "true"
    Option         "AllowGLXWithComposite" "true"
    Option         "NoLogo" "true"
    Option         "AddARGBGLXVisuals" "True"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

The auto-select for the DFP used to work right and select 1680x1050.  I've tried to manually set the DFP to 1680X1050, but the screen just turns black - I am assuming because either xorg or the nvidia drivers are not reading it as a valid resolution so they turn it off?  Any ideas on how to fix this?

Edit: fixed the dyslexic resolutions. smile  I did mean 1680x1050, not 1650x1080.

Re: Help with monitor resolution - can't get 1680x1050

I don't know anything about TwinView but the only way I could get my resolution to work properly was by adding:

    SubSection     "Display"
        Virtual     1280 800
        Depth       24
    EndSubSection

Perhaps you could plug in:

    SubSection     "Display"
        Virtual     1650 1080
        Depth       24
    EndSubSection

At least it's something to try, unless it conflicts with TwinView somehow. I'm not sure. I browsed another xorg.conf file at: http://javier.rodriguez.org.mx/download/dell/xorg.conf and saw this:

    Identifier    "Generic Video Card"
#    Driver        "nv"
    Driver        "nvidia"
    BusID        "PCI:1:0:0"
    Option "TwinView"
    #Option "MetaModes"                "1280x1024, 1440x900 @1440x1024; NULL, 1440x900"    # With vertical panning
    Option "MetaModes"                "1280x1024, 1440x900; NULL, 1440x900"
    Option "RenderAccel" "true"
    Option    "backingstore" "true"
    Option "XAANoOffsetScreenPixmaps" "true"
    Option "AddRGBGLXVisuals" "On"

Section "Monitor"
    Identifier    "Generic Monitor"
    Option        "DPMS"
    HorizSync    28-72
    VertRefresh    43-60
EndSection

Section "Monitor"
    Identifier    "External Monitor"
    Option        "DPMS"
    HorizSync    28-72
    VertRefresh    43-60
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Generic Video Card"
    Monitor        "Generic Monitor"
    DefaultDepth    24
    SubSection "Display"
        Depth        1
        Modes        "1440x900"
    EndSubSection
    SubSection "Display"
        Depth        4
        Modes        "1440x900"
    EndSubSection
    SubSection "Display"
        Depth        8
        Modes        "1440x900"
    EndSubSection
    SubSection "Display"
        Depth        15
        Modes        "1440x900"
    EndSubSection
    SubSection "Display"
        Depth        16
        Modes        "1440x900"
    EndSubSection
    SubSection "Display"
        Depth        24
        Modes        "1440x900"
    EndSubSection
EndSection

Section "Screen"
    Identifier    "External Screen"
    Device        "Generic Video Card"
    Monitor        "External Monitor"
    DefaultDepth    24
    SubSection "Display"
        Depth        1
        Modes        "1280x1024"
    EndSubSection
    SubSection "Display"
        Depth        4
        Modes        "1280x1024"
    EndSubSection
    SubSection "Display"
        Depth        8
        Modes        "1280x1024"
    EndSubSection
    SubSection "Display"
        Depth        15
        Modes        "1280x1024"
    EndSubSection
    SubSection "Display"
        Depth        16
        Modes        "1280x1024"
    EndSubSection
    SubSection "Display"
        Depth        24
        Modes        "1280x1024"
    EndSubSection
EndSection

I notice there's seperate variables for each monitor below. Perhaps it could be used as a template, unless you already have something like that. Or use that AND punch in the Virtual option instead of Modes.. I don't know.. Anyone else have ideas? hmm Wish I could be of more help.

I assume you mean 1680x1050, not 1650x1080.

I still have this issue too.  Whatever changed, has not been fixed with newer versions of the nvidia driver. =/

Do you happen to know what version of Xorg or the nVidia driver changed on April 1st?

If not, is there a way to see what day different versions of packages are released?  I've never really tried to do anything like that before.
