[mythtv-users] Mythbuntu defaulting to incorrect resolution

To add a bit more information… I'm wondering if something changed with
respect to the DVI output name. Specifically, Xorg.0.log shows my Sharp
LCD on DFP-0 with 1920x1080 being validated: 

---
[    15.320] (--) NVIDIA(0): Valid display device(s) on ION at PCI:1:0:0
[    15.320] (--) NVIDIA(0):     CRT-0
[    15.320] (--) NVIDIA(0):     SHARP LCD (DFP-0) (connected)
[    15.320] (--) NVIDIA(0):     DFP-1
[    15.320] (--) NVIDIA(0): CRT-0: 400.0 MHz maximum pixel clock
[    15.320] (--) NVIDIA(0): SHARP LCD (DFP-0): 330.0 MHz maximum pixel
clock
[    15.320] (--) NVIDIA(0): SHARP LCD (DFP-0): Internal Dual Link TMDS
[    15.320] (--) NVIDIA(0): DFP-1: 165.0 MHz maximum pixel clock
[    15.320] (--) NVIDIA(0): DFP-1: Internal Single Link TMDS
[    15.320] (**) NVIDIA(0): Using HorizSync/VertRefresh ranges from the
EDID for display
[    15.320] (**) NVIDIA(0):     device SHARP LCD (DFP-0) (Using EDID
frequencies has been
[    15.320] (**) NVIDIA(0):     enabled on all display devices.)
[    15.329] (II) NVIDIA(0): Validated MetaModes:
[    15.329] (II) NVIDIA(0):     "1920x1080+0+0"
---

However, it then sets the 1280x1024 resolution on DVI-D-0:

---
[    19.268] (II) NVIDIA(0): Setting mode "DVI-D-0: nvidia-auto-select
@1280x1024 +0+0"
---

I can use "xrandr --output DVI-D-0 --mode 1920x1080" to change the
resolution on the LCD after bootup. Unfortunately, I'm at a loss as to
why relatively simple xorg.conf isn't doing this for me from the start:

---
Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "ION"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Stereo" "0"
    Option         "TwinView" "0"
    Option         "metamodes" "1920x1080 +0+0"
    SubSection     "Display"
        Depth       24
        Modes       "1920x1080"
    EndSubSection
EndSection
---

Thanks,
Joe
