just want Xorg to just grab all input devices and then let xorg.conf.d<br>straighten it out.</blockquote>

<div>This works for me too. I guess I can also assume that we could ignore just one device by specifying MatchProduct with product ID, right? All this is for the next step with udev. Then my question is (sorry I have too many questions :):</div>
<div> </div>
<div>How does the current hal fdi work? Can we let it ignore a vendor by removing the fdi file? Looks like (from my testing result) something will pick the device up even if I totally remove the wacom fdi.</div>
