Getting Nvidia DVI output working without EDID


I managed to get vga output to work with the modeline below from the EDID values the monitor gave me, but EDID isn't working for DVI hence no screen.
Code:
Modeline "1680x1050DR" 146.25 1680 1784 1960 2240
                              1050 1053 1059 1089 -hsync +vsync

two startx -- -logverbose 5 and a nvidia-bug-report.log here:
log_files.tar.gz

for those of you to lazy to download the above file (pulled from VGA, nothing returns from DVI):

Code:
(--) NVIDIA(0): --- EDID for SceptreX20WC-Gamer (CRT-0) ---
(--) NVIDIA(0): EDID Version                 : 1.3
(--) NVIDIA(0): Manufacturer                 : SPT
(--) NVIDIA(0): Monitor Name                 : SceptreX20WC-Gamer
(--) NVIDIA(0): Product ID                   : 8338
(--) NVIDIA(0): 32-bit Serial Number         : 29
(--) NVIDIA(0): Serial Number String         : 
(--) NVIDIA(0): Manufacture Date             : 2006, week 51
(--) NVIDIA(0): DPMS Capabilities            : Active Off
(--) NVIDIA(0): Prefer first detailed timing : Yes
(--) NVIDIA(0): Supports GTF                 : Yes
(--) NVIDIA(0): Maximum Image Size           : 410mm x 310mm
(--) NVIDIA(0): Valid HSync Range            : 30.0 kHz - 92.0 kHz
(--) NVIDIA(0): Valid VRefresh Range         : 40 Hz - 86 Hz
(--) NVIDIA(0): EDID maximum pixel clock     : 170.0 MHz

(--) NVIDIA(0): Detailed Timings:
(--) NVIDIA(0):   1680 x 1050 @ 60 Hz
(--) NVIDIA(0):     Pixel Clock      : 146.25 MHz
(--) NVIDIA(0):     HRes, HSyncStart : 1680, 1784
(--) NVIDIA(0):     HSyncEnd, HTotal : 1960, 2240
(--) NVIDIA(0):     VRes, VSyncStart : 1050, 1053
(--) NVIDIA(0):     VSyncEnd, VTotal : 1059, 1089
(--) NVIDIA(0):     H/V Polarity     : -/+

(II) NVIDIA(0): Frequency information for SceptreX20WC-Gamer (CRT-0):
(II) NVIDIA(0):   HorizSync   : 30.000-92.000 kHz
(II) NVIDIA(0):   VertRefresh : 40.000-86.000 Hz
(II) NVIDIA(0):     (HorizSync from EDID)
(II) NVIDIA(0):     (VertRefresh from EDID)
I'm guessing I'm going to have to guess a modeline (maybe the one above will work?) and force it to work?

It is hard to say from just looking at the logs. It is also best to post /etc/X11/xorg.conf.

nVidia has provided an option to disable EDID. Add the following to /etc/X11/xorg.conf in the driver section where you specify nvidia as the driver.

Option "UseEDID" "False"

Use gtf to create modelines for your monitor. Place them in the monitor section.

Try using 'nvidia-settings', and configure the screens there.
