FWIW, I bisected to: commit 568d527caa4d0564b765ac082e948e19d1d22e13 Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Tue Jan 10 15:58:21 2017 +1000 touchpad: use pressure values for touch is-down decision ...and seems to be fixed by: commit 1dfedc6995cf63e004bd3e0b1d22ae263feb7362 Author: Paul Kocialkowski <contact@paulk.fr> Date: Fri Apr 28 15:29:03 2017 +0200 udev: Select more generic pressure range values for Elantech touchpads This actually uses the same pressure ranges I was trying in my own .hwdb file, but I didn't realise 1.7.1 didn't support that feature! So hopefully everything will be fine in the next release. Sorry for the noise. |
