this (live cds) won't work since he needs the nvidia drivers package to run
a widescreen resolution (livecds usually don't include proprietary drivers).
it also seems to have an old server (7.1, while the latest is 7.3 and 7.4 is
to be released soon), the nvidia drivers also seem quite old. also with that
xorg.conf it won't work unless with vesa modes (1024x768). Now, forst of all
you should upgrade xorg, xorg-server and nvidia drivers to the latest
available for your distro, or upgrade distro version, then set up the
xorg.conf where the relevant sections in xorg.conf should be like this:

Section "Monitor"
	Identifier   "Monitor0"
	ModelName    "LCD Panel"
	UseModes     "Modes[0]"

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"

Section "Modes"
        Identifier "Modes[0]"
        Modeline "1360x768 at 60" 84.50 1360 1392 1712 1744 768 783 791 807

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1366x768" #maybe this needs to be "1366x768 at 60", but i'm
not sure. try one or the other.

Section "ServerLayout"
	Identifier    "single head configuration"
	Screen        "Screen0"
	InputDevice   "Keyboard0" "CoreKeyboard"
#where's the mouse? does it works? it should have a line similar to
the keyboard one.

so, recap: update xorg, xorg-server and nvidia drivers, set up the right
xorg.conf and retry.
