great. the touchpad doesn't even look like a touchpad, it just does the mouse emulation. So to libinput (and the rest of userspace) it just looks like a 5-button mouse with 2 scroll wheels. Until we have kernel support for that there isn't much you can do beyond trying to increase the pointer acceleration to maximum speed. I see, that's not so nice. I will store the device in a drawer then. Thank you for your time and analysis. Let me know if I can help with testing. closing this bug for now, this needs to be fixed in the kernel first. Please raise a bug there or if you're really keen you can start reverse-engineering the protocol HP uses for these devices. Even this bug is closed, I would be interested in having a look at the raw events of your touchpad. Could you please attach a hid-recorder (project hid-replay[1]) of few events reported by your device? [1] http://bentiss.github.io/hid-replay-docs/ Created attachment 120316 [details]

Thanks for the logs. From a HID point of view, your touchpad is seen with 2 types of reports, one for the buttons/wheel and one for the mouse events. There is nothing there which allows to think that there is a hidden mode where the touchpad sends true multitouch data. There is nothing I can do for you, sorry. You might have more success by reverse engineering the protocol the windows driver uses, but this goes beyond the scope of this bug. Plus, I am not even sure that such a mode exists. So that I bought a crap, good to know. Thanks for your feedback. |
