The problem I had with this is how that additional input device is presented in userland. As long as the capabilities are set properly for each input device, I have no problem using one catch-all match in the device id list. >> 3) It works well with the synaptics and multitouch X drivers > > I guess it depends on what the plan is for MT support in the userland. > If our goal is to make the MT X driver generic, there would be no need > to have a Wacom X drvier for MT (I'd love to go with this route).

The next Ubuntu release comes with gestures, and the Bamboo works in that framework too. Real MT through X will become reality within the next six months. I think it is safe to say that there is no need to add MT to the Wacom driver. >> 4) It does not work well with the wacom X driver (!) > > This would not be an issue if we (as a team working in the community) > can answer item 3 above properly. > >> In particular the last point may seem upsetting, but my reasoning is >> simply that the wacom X driver really supports tablets and not >> trackpads.

Then so be it. :-) Cheers, Henrik -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
