** Description changed: Some laptop touchpads are annoyingly unresponsive when the software implements any kind of hysteresis. This is a regression caused by the introduction of libinput, visible on at least Lenovo X1 Carbon gen 4 and 5, Dell XPS 13, and Apple Macbook Air. WORKAROUND (1) 1. Log into "Ubuntu on Xorg" only. This workaround only works for Xorg. 2. sudo apt install xserver-xorg-input-synaptics 3. Tweak your personal preferences using 'synclient' (the GUI settings won't work any more). For example: - synclient HorizHysteresis=0 VertHysteresis=0 + synclient HorizHysteresis=0 VertHysteresis=0 WORKAROUND (2) 1.
