Comment 119 for bug 549447

For whatever reason, my egalax touchscreen gets confused with a synaptics touchpad, not the evdev driver. I had to change the above fdi file - specifically the "contains" part didn't match my device:

<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
  <device>
    <match key="info.product" contains="eGalax INC. USB TouchController">
      <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">/etc/egalax.cal</merge>
      </match>
    </match>
  </device>
</deviceinfo>

I put it in /etc/hal/fdi/policy, which is probably what the above post was referring to. After doing this, the touchscreen is loaded in xorg via hal using the egalax driver. I still have a problem where I can list the device in hal, and input.x11_parameters says /etc/egalax.cal, but the xorg driver doesn't seem to get this information, and is looking for the calibration file in the default location /var/lib/eeti.param.

udi = '/org/freedesktop/Hal/devices/usb_device_eef_1_noserial_if0_logicaldev_input'

Also, I had more success with the latest beta driver (1.07) from eeti:
