Comment 114 for bug 549447

Ok, I agree with you. I can remove the egalax driver from xorg.conf and the touchscreen doesn't create any input events when touched.

I'm trying to setup an fdi file like Max suggested. My first goal is to get xorg to stop trying to load the synaptics driver for the eGalax touchscreen. I edited /usr/share/hal/fdi/policy/20thirdparty/10-synaptics.fdi (I know I'm supposed to put it in /etc/hal/fdi/... so it doesn't get overwritten, but I'd rather just have a single copy of the file while I'm testing). The file starts out like this (comments removed):

<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.touchpad">
        <merge key="input.x11_driver" type="string">synaptics</merge>
    </match>
  </device>
</deviceinfo>

I changed it to this:

<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.touchpad">
        <match key="info.product" contains="Synaptics TouchPad">
            <merge key="input.x11_driver" type="string">synaptics</merge>
        </match>
    </match>
  </device>
</deviceinfo>

My actual synaptics touchpad is identified by xorg/hal as:

(II) config/hal: Adding input device SynPS/2 Synaptics TouchPad

And the touchscreen is identified by xorg/hal as:

(II) config/hal: Adding input device eGalax INC. USB TouchController

Yet with the above changed fdi file I still get xorg trying to use the synaptics driver for the eGalax device:

(II) config/hal: Adding input device eGalax INC. USB TouchController
(II) Synaptics touchpad driver version 1.1.0
(**) Option "Device" "/dev/input/event7"
(--) eGalax INC. USB TouchController: no supported touchpad found
(EE) eGalax INC. USB TouchController Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "eGalax INC. USB TouchController"
(II) UnloadModule: "synaptics"
(EE) config/hal: NewInputDeviceRequest failed (8)

I know the fdi file is being parsed, because I can add extra Synaptics options there, and they show up for both the eGalax and synaptics devices in the xorg server log.

Do you see a problem with what I'm doing?

Thanks again for your help.
