For me at least the problem isn't palm detection, because in the end it's a kludge that can at best only partially work. For synaptics the solution for this is syndaemon, and the problem it's broken right now: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=818471 Maybe libinput does the typing detection syndaemon does, but I can't find any evidence for it. > Tapping and two-finger scrolling work perfectly fine with the xinput > driver, too. As a touchpad that doesn't move the mouse as I type is hugely attractive, I tried libxinput again. Same result. Palm detection works wonderfully, but only because it doesn't recognise a tap from finger either. Clicking (ie a tap heavy enough to activate the mechanical switch underneath) does work. If I configure synaptics to ignore TapButton1 taps (as opposed to clicks), it also has faultless palm detection.
