libinput vs synaptics and evdev in ubuntu 18.04 (and derivatives)
[I recognize this is a out of place, sorry about that in advance, but couldn't find anything about this anywhere on the internet:]
IMO, in 18.04, libinput works better than synaptics and evdev (comparing unpatched versions), and mouse dynamics is quite improved wrt my previous experience with patched evdev in 16.04.
However, I couldn't find a way to disable touchpad while keeping trackpoint tapping enabled (not strange as it comes from the same hardware, and the reason a patch would be needed), neither a way to disable the touchpad motion entirely (only possible when typing; this is a libinput limitation).
It would be awesome if somebdy could find the way to patch libinput so touchpad could be disabled without affecting the trackpoint buttons.
