Using a Dell 2007WFP Panel: 1680×1050 DVI on Linux

I ran into an issue configuring Linux (Ubuntu specifically) to use the native 1680×1050 resolution of a Dell 2007WFP widescreen monitor. So I came up with a modeline that worked, and thought I’d post it here. Following are the relevant sections my xorg.conf

BTW, I’m using the Ubuntu-provided NVidia drivers, and running a generic FX5200 card. Note that this is for the DVI input only (119mhz). Modelines for the analog input will be different. (Link to Dell’s documentation)

Section "Device"
	Identifier	"NVIDIA"
	Driver		"nvidia"
# The BusID will be different for you. I'm running an odd
# PCI riser on a MiniITX motherboard, hence the odd numbering
	BusID		"PCI:2:9:0"
	Option "ModeValidation" "NoMaxPClkCheck"
EndSection

Section "Monitor"
	Identifier	"DELL 2007WFP"
	Option		"DPMS"
#			      DCF   HR   SH1  SH2  HFL  VR   SV1  SV2  VFL
	ModeLine	"1680x1050" 119.0 1680 1728 1760 1840 1050 1053 1059 1080 -HSync +VSync
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"NVIDIA"
	Monitor		"DELL 2007WFP"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1680x1050" "1280x960" "1280x1024"
		ViewPort	0 0
	EndSubSection
EndSection

After much fiddling, this works nicely for me. Hope this helps someone in the same boat.

    I had a similar problem, 1680×1050 worked on the analog output, but not on DVI. What solved the problem:

    Section "Device"
    Option      "ExactModeTimingsDVI"   "yes"
    
    Section "Monitor"
    Option      "ModeValidation"            "NoMaxPClkCheck"
