Created attachment 124561 [details] libinput device propierties It seems that libinput doesn't support my touchpad with multiouch gestures support. The computer case model is Clevo W330AU link: http://www.clevo.com.tw/clevo_prodetail.asp?id=822&lang=en When I debug the events and do swipe gesture with 3+ fingers it doesn't show any output. My current version of libinput is 1.3.1 in Arch Linux with Gnome 3.20.

This is the key here: # Property type 3 (INPUT_PROP_SEMI_MT) Semi-mt touchpads are those that can only provide us a bounding box of all fingers rather than the actual position of each finger. In doing so, the resolution drops to about half whenever a second finger is on the touchpad (the third finger doesn't provide any position, it's just a bit that there is a third finger down). We had gestures for a while on semi-mt devices but because of the resolution issues we removed it, these devices simply aren't capable of enough precision to make gesture detection reliable. sorry. so libinput not handling a three-finger gesture on these devices is correct behaviour.
