Karl, thank you for your original post as it 'lit a fire' that
prompted me to get on this input issue.

Wow, um, I certainly need to use the resource that /usr/share/doc is.
That README.gz is readable, not complete with examples, but readable.

This is what I have now (I was hoping to stick with hand editing):

>> Section "InputDevice"
>> 	Identifier	"Configured Mouse"
>> 	Driver		"mouse"
>> 	Option		"CorePointer"
>>  	Option		"Device"		"/dev/input/mice"
>> 	Option		"Protocol"		"ImPS/2"
>>         Option		"Emulate3Buttons"	"true"
>> 	Option		"ZAxisMapping"		"4 5"
>> EndSection
>> Section "InputDevice"
>>         Identifier      "Synaptics Touchpad"
>>         Driver          "synaptics"
           Option          "TapButton1"            "1"
           Option          "MaxTapTime"            "180"
           Option          "MaxTapMove"            "220"
>>         Option          "SendCoreEvents"        "true"
>>         Option          "Device"                "/dev/psaux"
>>         Option          "Protocol"              "auto-dev"
>>         Option	   "HorizScrollDelta"      "0"
>> EndSection

You are the second person to point me in this direction -- I am getting
the idea that I need to be able to read this log. I did

man Xorg.0.log

(yielding nothing) and, 

man xorg

showed me the


switch. Would this switch help me read Xorg.0.log? I'll read, but how
would I use this switch?

I actually prefer this as, for instance, I have never been able to
learn much from using emacs' customize feature and then trying to
translate that into handwritten configuration in my dotemacs.

Done (as above). But I have to 'wack' the touchpad repeatedly before,
for instance, an app button responds. I have tried the sensitivity
adjustment in,

System > Preferences > Mouse > Motion

but I don't get the idea that this has anything to do with my
issue. What is the actual disjunction between the xorg.conf section
and the GUI? (if that's any of my business!)

And I am off to try synclient even though it is not my style.
