I'm reviving / rewriting xf86-input-tslib, the main sources now living at https://github.com/merge/xf86-input-tslib With tslib, I *am* somewhat pushing towards having evdev kernel drivers. (Sadly, there are *real* userspace drivers in tslib because there's no proper driver, but I don't have the hardware to write them; even more sadly, there are companies that still ship tslib drivers in their BSPs instead of kernel drivers) but that's a different thing. tslib itself lives at http://tslib.org So the real reason I need tslib is the filter stack and easy to use graphical calibration (and the little dependencies and portability are a bonus too). All these "drivers" :) To me, xf86-input-tslib is no driver. tslib (or the libts library) isn't either. It's either a userspace driver as tslib module or a proper kernel driver. But, oh well :) I'm getting off track here, but libinput is really interesting in that it does gesture recognition too. Do you somehow sync that work with gtk+ or others who do that too? >> >>> For testing purposes, I'd like to configure my laptop's touchpad for the >>> driver to use.

Sure. thanks Peter for getting back at me.
