+.BI "Option \*qMergedFB\*q \*q" boolean \*q
+This enables merged framebuffer mode.  In this mode you have a single 
+shared framebuffer with two viewports looking into it.  It is similar
+to Xinerama, but has some advantages.  It is faster than Xinerama, the
+DRI works on both heads, and it supports clone modes.  
+.br
+Merged framebuffer mode provides two linked viewports looking into a
+single large shared framebuffer.  The size of the framebuffer is 
+determined by the
+.B Virtual
+keyword defined on the
+.B Screen
+section of your XF86Config file.  It works just like regular virtual
+desktop except you have two viewports looking into it instead of one.
+.br
+For example, if you wanted a desktop composed of two 1024x768 viewports
+looking into a single desktop you would create a virtual desktop of 
+2048x768 (left/right) or 1024x1536 (above/below), e.g.,
+.br
+.B Virtual 2048 768
+or
+.B Virtual 1024 1536
+.br
+The virtual desktop can be larger than larger than the size of the viewports
+looking into it.  In this case the linked viewports will scroll around in the 
+virtual desktop.  Viewports with different sizes are also supported (e.g., one
+that is 1024x768 and one that is 640x480).  In this case the smaller viewport
+will scroll relative to the larger one such that none of the virtual desktop 
+is inaccessable.  If you do not define a virtual desktop the driver will create
+one based on the orientation of the heads and size of the largest defined mode in 
+the display section that is supported on each head.

+.BI "Option \*qMetaModes\*q \*q" "string" \*q
+MetaModes are mode combinations for CRT1 and CRT2.  If you are using merged
+frame buffer mode and want to change modes (CTRL-ALT-+/-), these define which
+modes will be switched to on CRT1 and CRT2.  The MetaModes are defined as 
+CRT1Mode-CRT2Mode (800x600-1024x768).  Modes listed individually (800x600) 
+define clone modes, that way you can mix clone modes with non-clone modes.
+Also some programs require "standard" modes.  
+.br
+Note:  Any mode you use in the MetaModes must be defined in the
+.B Screen 
+section of your XF86Config file.  Modes not defined there will be ignored when
+the MetaModes are parsed since the driver uses them to make sure the monitors can 
+handle those modes.  If you do not define a MetaMode the driver will create
+one based on the orientation of the heads and size of the largest defined mode in 
+the display section that is supported on each head.

+.BI "Option \*qNoMergedXinerama\*q \*q" boolean \*q
+Since merged framebuffer mode does not use Xinerama, apps are not able to intelligently

+Xinerama compliant applications to place windows appropriately.  There are some caveats.
+Since merged framebuffer mode is able to change relative screen sizes and orientations on
+the fly, as well has having overlapping viewports, pseudo-Xinerama, might not always 
+provide the right hints.  Also many Xinerama compliant applications only query Xinerama
+once at startup; if the information changes, they may not be aware of the change.  If
+you are already using Xinerama (e.g., a single head card and a dualhead card providing
+three heads), pseudo-Xinerama will be disabled.
