Dave,

This may depend, in part, on the video card being used.  For example, my 
system has an NVidia graphics card.  To get the best support for its 
features, I'm using the NVidia proprietary ;( driver, which has a setup 
program called 'nvidia-settings' that configures dual monitor setup.

The program has an option to save to the X config file.  What I have in 
that file, now, is:

...
Section "ServerFlags"
     Option         "Xinerama" "0"
EndSection
...
Section "Monitor"

     # HorizSync source: edid, VertRefresh source: edid
     Identifier     "Monitor0"
     VendorName     "Unknown"
     ModelName      "DELL 2007FP"
     HorizSync       30.0 - 83.0
     VertRefresh     56.0 - 76.0
     Option         "DPMS"
EndSection
...
Section "Device"
     Identifier     "Videocard0"
     Driver         "nvidia"
     VendorName     "NVIDIA Corporation"
     BoardName      "Quadro FX 4000"
     Option         "XAANoOffscreenPixmaps" "true"
EndSection
...
Section "Screen"
     Identifier     "Screen0"
     Device         "Videocard0"
     Monitor        "Monitor0"
     DefaultDepth    24
     Option         "TwinView" "1"
     Option         "metamodes" "DFP-0: 1600x1200 +0+0, DFP-1: 1600x1200 
+1600+0;
  DFP-0: 1024x768 +0+0, DFP-1: nvidia-auto-select +1024+0; DFP-0: 
800x600 +0+0, D
FP-1: nvidia-auto-select +800+0; DFP-0: 640x480 +0+0, DFP-1: 
nvidia-auto-select
+640+0"
     Option         "RenderAccel" "True"
     Option         "AllowGLXWithComposite" "True"
     Option         "AddARGBGLXVisuals" "True"
     Option         "DisableGLXRootClipping" "True"
     SubSection     "Display"
         Depth       24
         Modes      "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
     EndSubSection
EndSection
...
Section "Extensions"
     Option         "Composite" "Enable"
EndSection
...

These are, I hope, all the relevant sections for my display setup. 
Whether they are any help or not, depends.

As for the window manager, I'm not using icewm, so I can't speak to 
whether any of this would work with it or not.
