WXGA is 1280x800: http://whatis.techtarget.com/definition/WXGA

In Leap I put my xrandr script in

	/etc/X11/xinit/xinitrc.d/setup

Note that I have no Optimus, Bumblebee or laptop, so YMMV. Also my only
"1366x768" native display is actually a 1360x768 Samsung TV[1], which worked
with Xorg @1360x768 automatically the few times I tried it, and used 1920x1080
when I put that mode in an xrandr startup script. Most of the displays I use are
natively 1680x1050 or higher.

Something else you might try is an xorg.conf file that includes HorizSync,
VertRefresh and PreferredMode, from which Xorg should *automatically* generate
usable modelines. If you can't find the Horiz and Vert specs online or in a
manual, try the commands I used for the data collection below. The following
started X up @1920x1080 (though ugly) on mine:

	Section "Monitor"
		Identifier	"DefaultMonitor"
		Option		"DefaultModes"	"on"
		Option		"PreferredMode"	"1920x1080"
		VendorName	"Samsung"
		ModelName	"SAM32C450"
		HorizSync	26-68
		VertRefresh	24-75
	EndSection
