Have a look in /etc/Xorg/xorg.conf

Mine has this section, which I think I edited by hand. My monitor config does 
survive reboots.

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "Screen0" 0 0
        Screen      1  "Screen1" RightOf "Screen0"
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection


"man xorg.conf" gives the syntax. Here is the section for the "Screen" part of 
"ServerLayout"

Screen  screen-num "screen-id" position-information
	One  of  these  entries must be given for each screen being used in
	a session.  The screen-id field is mandatory, and specifies the Screen 
	section  being  referenced.
	The  screen-num  field is optional, and may be used to specify the
	screen number in multi-head configurations.  When this field is
	omitted, the screens  will  be  numbered  in the order that they are
	listed in.  The numbering starts from 0, and must be consecutive. 
	The position-information field describes the way multiple  screens
	are  positioned.  There are a number of different ways that this
	information can be provided:

              x y

              Absolute  x y
                  These both specify that the upper left corner’s coordinates
                  are (x,y).  The Absolute keyword is optional.  Some older
                  versions of XFree86 (4.2  and  earlier) don’t  recognise the
                  Absolute keyword, so it’s safest to just specify the
                  coordinates without it.

              RightOf   "screen-id"

              LeftOf    "screen-id"

              Above     "screen-id"

              Below     "screen-id"

              Relative  "screen-id" x y
                  These give the screen’s location relative to another screen.
                  The  first  four position  the  screen immediately to the
                  right, left, above or below the other screen. When
                  positioning to the right or left, the top edges  are
                  aligned. When positioning above or below, the left edges are
                  aligned. The Relative form specifies the offset of the
                  screen’s origin (upper left corner) relative to the
                  origin of another screen.
