That may well be true, as I am not familiar with the code. Maybe you can point out what I'm missing? This is the output of (set -x; xinput; xinput list-props 15) when the libinput driver (ie the new default) is in use: + + xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=12 [slave pointer (2)] ⎜ ↳ DLL06E4:01 06CB:7A13 Touchpad id=13 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=15 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ Sleep Button id=10 [slave keyboard (3)] ↳ Integrated_Webcam_HD id=11 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)] ↳ Dell WMI hotkeys id=16 [slave keyboard (3)] + xinput list-props 15 Device 'SynPS/2 Synaptics TouchPad': Device Enabled (137): 1 Coordinate Transformation Matrix (139): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Tapping Enabled (278): 1 libinput Tapping Enabled Default (279): 0 libinput Tapping Drag Enabled (280): 1 libinput Tapping Drag Enabled Default (281): 1 libinput Tapping Drag Lock Enabled (282): 1 libinput Tapping Drag Lock Enabled Default (283): 0 libinput Accel Speed (284): 0.102881 libinput Accel Speed Default (285): 0.000000 libinput Natural Scrolling Enabled (286): 0 libinput Natural Scrolling Enabled Default (287): 0 libinput Send Events Modes Available (258): 1, 1 libinput Send Events Mode Enabled (259): 1, 1 libinput Send Events Mode Enabled Default (260): 0, 0 libinput Left Handed Enabled (288): 0 libinput Left Handed Enabled Default (289): 0 libinput Scroll Methods Available (290): 1, 1, 0 libinput Scroll Method Enabled (291): 1, 0, 0 libinput Scroll Method Enabled Default (292): 1, 0, 0 libinput Click Methods Available (293): 1, 1 libinput Click Method Enabled (294): 1, 0 libinput Click Method Enabled Default (295): 1, 0 libinput Disable While Typing Enabled (296): 0 libinput Disable While Typing Enabled Default (297): 1 Device Node (261): "/dev/input/event1" Device Product ID (262): 2, 7 libinput Drag Lock Buttons (298): <no items> libinput Horizonal Scroll Enabled (263): 1 The touchpad didn't recognise tapping of any sort after boot. It did however recognise a two fingered drag as a scroll. I then set few properties using "xinput set-prop 15 ..." (278, 259, 284, 296). None had any effect I could detect. Setting 291 and 294 looked enticing but I could not figure out the syntax xinput wanted. I enable the synaptics driver using /etc/X11/xorg.conf.f/touchpad.conf: Section "InputClass" Identifier "Touchpad twofinger scroll" MatchIsTouchpad "yes" Driver "synaptics" Option "ZAxisMapping" "4 5" Option "HorizTwoFingerScroll" "true" Option "VertTwoFingerScroll" "true" Option "FastTaps" "on" Option "AccelFactor" "0.1028806" #2x Option "MinSpeed" "1" Option "MaxSpeed" "4.75" Option "TapButton1" "1" Option "TapButton2" "3" Option "TapButton3" "2" EndSection With the synaptics driver the touchpad works as you would expect.

Not that it matters - setting with synclient or via the Xorg config works fine. It would be nice if libinput worked, as syndaemon doesn't work now and I see libinput has a "Disable While Typing Enabled" option. It would be wonderful to have that again.
