This is similar to a bunch of other "horizontal scroll does not work" bugs, but I did not find any of those that were close enough that I could call this a duplicate.

The mouse is a Compaq CPQ750TP. It shows up as "Acrox USB & PS/2 Mouse" when plugged into the PC directly, and "ATEN CS1784" when plugged into my KVM (it works identically regardless how it is plugged in).
The mouse has a scroll ball and 5 buttons.
I have spent quite some time attempting to get the horizontal scrolling to work.
I have the following in a .fdi file in the /etc/hal/fdi/policy directory:

<?xml version="1.0" encoding="ISO-8859-1"?>

<deviceinfo version="0.2">

  <device>
    <match key="info.product" string="Acrox USB &amp; PS/2 Mouse">
      <merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
    </match>
  </device>

  <device>
    <match key="info.product" string="ATEN CS1784">
      <merge key="input.x11_options.ButtonMapping" type="string">1 2 3 4 5 10 11 8 9 6 7</merge>
      <merge key="input.x11_options.Emulate3Buttons" type="string">0</merge>
      <merge key="input.x11_options.EmulateWheelButton" type="string">0</merge>
      <merge key="input.x11_options.XAxisMapping" type="string">10 11</merge>
    </match>
  </device>
</deviceinfo>

Horizontal scrolling works perfectly on Windows 2000 (different computer, same KVM & mouse)
Attempting to scroll horizontally in Ubuntu gets fast vertical scrolling.

If I monitor events with "xinput test 4" Left button maps to button 1, middle button (pushing down on ball) maps to button 2, right button maps to button 3 left side button maps to button 8, right button maps to button 9, vertical scroll with ball maps to buttons 4 & 5, horizontal scroll with ball also maps to buttons 4 & 5, but each event is repeated 7 times.

It appears as if horizontal scrolling should be mapping to buttons 6 & 7. The hal file above was an attempt at a work arround to remap 6 & 7 to 10 & 11, but the remapping to 4 & 5 is still happening.

Wild speculation: someone has hard wired his preferences into the driver.

$ lsb_release -rd
Description: Ubuntu 8.10
Release: 8.10

Not sure where this problem is happening, but my guess is evdev.

Horizontal scrolling is very important to me. I do CAD work, and being able to scroll in two dimensions around a large drawing is very helpful. To that end, I have purchased at least 8 different mice with scroll balls on them trying to find one that works well.
