It seems that there is no 3 finger swipe gesture feature, at least in the 1.6.3 version of libinput. Maybe it's just a bug but I can't use it and in the manual of libinput it appears that 3 finger is not supported : Option "ScrollMethod" "string" Enables a scroll method. Permitted values are none, twofinger, edge, button. Not all devices support all options, if an option is unsupported, the default scroll option for this device is used.
we've had three-finger swipes for quite a while now, but gestures are disabled on some touchpads that are unreliable. Maybe your touchpad is one of them? Attach an evemu-record output of a gesture to be sure please, libinput-debug-events --verbose may have some info too.
I have this, I don't know if this means that my touchpad is reliable : # EVEMU 1.3 # Kernel: 4.10.8-200.fc25.x86_64 # DMI: dmi:bvnInsyde:bvrF.11:bd12/09/2016:svnHP:pnHPENVYNotebook13-ab0XX:pvrType1ProductConfigId:rvnHP:rn82B9:rvrKBCVersion03.18:cvnHP:ct10:cvrChassisVersion: # Input device name: "SynPS/2 Synaptics TouchPad" # Input device ID: bus 0x11 vendor 0x02 product 0x07 version 0x1b1 # Supported events: # Event type 0 (EV_SYN) # Event code 0 (SYN_REPORT) # Event code 1 (SYN_CONFIG) # Event code 2 (SYN_MT_REPORT) # Event code 3 (SYN_DROPPED) # Event code 4 ((null)) # Event code 5 ((null)) # Event code 6 ((null)) # Event code 7 ((null)) # Event code 8 ((null)) # Event code 9 ((null)) # Event code 10 ((null)) # Event code 11 ((null)) # Event code 12 ((null)) # Event code 13 ((null)) # Event code 14 ((null)) # Event type 1 (EV_KEY) # Event code 272 (BTN_LEFT) # Event code 325 (BTN_TOOL_FINGER) # Event code 328 (BTN_TOOL_QUINTTAP) # Event code 330 (BTN_TOUCH) # Event code 333 (BTN_TOOL_DOUBLETAP) # Event code 334 (BTN_TOOL_TRIPLETAP) # Event code 335 (BTN_TOOL_QUADTAP) # Event type 3 (EV_ABS) # Event code 0 (ABS_X) # Value 3437 # Min 1350 # Max 5652 # Fuzz 0 # Flat 0 # Resolution 40 # Event code 1 (ABS_Y) # Value 1931 # Min 1164 # Max 4758 # Fuzz 0 # Flat 0 # Resolution 69 # Event code 24 (ABS_PRESSURE) # Value 0 # Min 0 # Max 255 # Fuzz 0 # Flat 0 # Resolution 0 # Event code 28 (ABS_TOOL_WIDTH) # Value 0 # Min 0 # Max 15 # Fuzz 0 # Flat 0 # Resolution 0 # Event code 47 (ABS_MT_SLOT) # Value 1 # Min 0 # Max 1 # Fuzz 0 # Flat 0 # Resolution 0 # Event code 53 (ABS_MT_POSITION_X) # Value 0 # Min 1350 # Max 5652 # Fuzz 0 # Flat 0 # Resolution 40 # Event code 54 (ABS_MT_POSITION_Y) # Value 0 # Min 1164 # Max 4758 # Fuzz 0 # Flat 0 # Resolution 69 # Event code 57 (ABS_MT_TRACKING_ID) # Value 0 # Min 0 # Max 65535 # Fuzz 0 # Flat 0 # Resolution 0 # Event code 58 (ABS_MT_PRESSURE) # Value 0 # Min 0 # Max 255 # Fuzz 0 # Flat 0 # Resolution 0 # Properties: # Property type 0 (INPUT_PROP_POINTER) # Property type 2 (INPUT_PROP_BUTTONPAD) N: SynPS/2 Synaptics TouchPad I: 0011 0002 0007 01b1 P: 05 00 00 00 00 00 00 00 B: 00 0b 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 01 00 00 00 00 00 B: 01 20 e5 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 01 00 00 00 00 00 00 00 00 B: 02 00 00 00 00 00 00 00 00 B: 03 03 00 00 11 00 80 60 06 B: 04 00 00 00 00 00 00 00 00 B: 05 00 00 00 00 00 00 00 00 B: 11 00 00 00 00 00 00 00 00 B: 12 00 00 00 00 00 00 00 00 B: 14 00 00 00 00 00 00 00 00 B: 15 00 00 00 00 00 00 00 00 B: 15 00 00 00 00 00 00 00 00 A: 00 1350 5652 0 0 40 A: 01 1164 4758 0 0 69 A: 18 0 255 0 0 0 A: 1c 0 15 0 0 0 A: 2f 0 1 0 0 0 A: 35 1350 5652 0 0 40 A: 36 1164 4758 0 0 69 A: 39 0 65535 0 0 0 A: 3a 0 255 0 0 0

right, so the touchpad only supports 2 finger touch positions (max slot is 1, i.e. 2 slots), the third finger can be detected but not placed on the touchpad. This will improve with the RMI4 patches scheduled for the kernel (you may then run into Bug 99830). For now, what's likely happening here is that the first two fingers detected are vertically too far apart (there's a threshold), so libinput guesses that it's a pinch gesture and then goes with that since it cannot tell where the third finger is. This is fixable, but I probably won't have time for it in the near future, let me know if you want to have a go at this.
