Comment 118 for bug 549447

You mean the one that I mentioned in #35?
here it is

<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
  <device>
    <match key="info.product" contains="USB Touchscreen 0eef:0001">
      <match key="info.capabilities" contains="input">
        <merge key="input.x11_driver" type="string">egalax</merge>
        <merge key="input.x11_device" type="string">usbauto</merge>
        <merge key="input.x11_parameters" type="string">/var/lib/eeti.param</merge>
      </match>
    </match>
  </device>
</deviceinfo>

I use it in a file named 50-eGalax-etti.fdi placed in /etc/fdi/policy
This inhibits for me that the evdev driver is loaded for the touchscreen which
leads to double events IMHO. Dont know if this helps in the synapic case also
