Exclamation Display resolution wrong on Dell Lat D410 (Ubuntu 13.04) with S-Video


I am using a Dell Latitude D410 with Ubuntu 13.04. I'm trying to connect it to a Sony Wega widescreen TV (using a S-Video cable) to watch YouTube but the display resolution is set wrong. It should be 1280x720, but instead, Ubuntu is setting it to 1024x768. I know some shell skills, but I am a newbie to display administration. Please help.

Arrow Steps taken

I've tried setting it via the graphical app and the xrandr -s command.

i recommend using gtf to generate the appropriate modeline, then creating /etc/X11/xorg.conf file (or an appropriate fragment in /etc/X11/xorg.conf.d) to invoke that mode. Something like

Code:
~$ gtf 1280 720 60

  # 1280x720 @ 60.00 Hz (GTF) hsync: 44.76 kHz; pclk: 74.48 MHz
  Modeline "1280x720_60.00"  74.48  1280 1336 1472 1664  720 721 724 746  -HSync +Vsync
then an xorg.conf file looking like (or including) the following:
Code:
Section "Monitor"

	#UseModes     "Modes0" #monitor0usemodes
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "Monitor Model"
	DisplaySize  432	270
	HorizSync    30.0 - 86.0
	VertRefresh  56.0 - 76.0
  Modeline "1280x720_60.00"  74.48  1280 1336 1472 1664  720 721 724 746  -HSync +Vsync
EndSection


Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor0"
	SubSection "Display"
		Viewport   0 0
		Depth     24
        Option "IgnoreEDID" "TRUE"
		Modes    "1280x720" "1024x768"
	EndSubSection
EndSection

The files don't exist. I've tried creating them but xrandr still doesn't find them.

EDIT1: COMPUTER BREAKDOWN! Full reinstall required!
