Back in October Chase Douglas [1] kicked off a flurry of patches and discussions on this mailing list about adding Clickpad support, and/or some form of multitouch gesture processing (what little is possible with Synaptics Advanced Gesture Mode) to the xf86-input-synaptics driver (and/or the kernel). The patches were commented upon, and rehashed a little... but now everything seems to have died down - and, as far as I can tell, nothing has yet been accepted into xf86-input-synaptics upstream.
[1] Starting with this: http://lists.x.org/archives/xorg-devel/2010-October/013809.html As a result of this work, in late December Henrik Rydberg submitted a patch [2] to linux-input, based on the discussions above, which added semi-mt support to the synaptics kernel driver. This patch, too, though, has not yet been accepted upstream. [2] https://patchwork.kernel.org/patch/426561/ 1. What is the status of the kernel driver patches? 2. What is the status of the effort to use them from user space? 1. Are patches still being reviewed/tested/worked on for xf86-input-synaptics to use Synaptics AGM to improve clickpad performance? 2. Was a decision made to not bother with xf86-input-synaptics, and instead to focus only on mtdev & xf86-input-multitouch? 3. Is semi-mt supported in mtdev? 3. What is the status of xf86-input-multitouch, anyway? It doesn't appear to be an "official" X input driver, supported and maintained, for example, by this mailing list. 4. And what about utouch? 1. Is that replacing mtdev/xf86-input-multitouch? 2. Is it Ubuntu specific? 3. Or is it being merged into the X.org / Xinput2 system? 4. Or will it live as an independent but cooperative userspace component of an X system? Sorry for jumping in, late to the party, and asking so many potentially off-topic questions to the mailing list at large. I'm more than happy to post elsewhere if more appropriate. This just seems like a good place to start. Thanks, -Daniel
