I've recently moved to libinput from synaptic, as I am using Gnome 3.20 and synaptics drivers aren't supported anylonger. The internal touchpad is working without issues (tap and click, two finger scrolling and two finger simulate right button), but the external touchpad (integrated in the logitech K400 keyboard), that used to work in the same way as the internal touchpad, now has tap and click disabled. two finger scrolling works. Please help me re-enabling tap and click on the Logitech K400 Plus keyboard.

Thank you in advance for your support!
Please attach an evemu-record of the k400 with a short tapping sequence, thanks.
Created attachment 124118 [details] logitech K400 plus tap-and-click evemu-record log Sorry for the delay. here is a evemu-record log with the tap sequence on my k400 plus. the sequence is: - single finger tap - two fingers tap - three fingers tap - four fingers tap thanks for any help!

this isn't a libinput issue and I wonder whether this ever worked in synaptics because this thing doesn't actually look like a touchpad (and never has, if my memory serves me right because we never figured out the magic sequence to switch it to touchpad mode). the device looks like a normal mouse (REL_X, REL_Y) rather than touchpads' absolute ABS_X/ABS_Y or ABS_MT_POSITION_X/ABS_MT_POSITION_Y on multitouch-capable devices. since these trigger the ID_INPUT_TOUCHPAD udev tag that we use to match for synaptics I doubt this device was ever synaptics-controlled. evdev would've been the fallback but it doesn't support tapping. so yeah, I doubt this really ever worked as a touchpad. note that in the evemu output you posted there are no tapping events, only the ctrl+c to cancel evemu is visible. so basically: this device works as expected, though it doesn't work like a touchpad because we don't have the magic codes to make it look like a touchpad and thus rely on the firmware.
I can guarantee that it used to work on my arch linux as touchpad with xf86-input-synaptics driver, with the same functionalities as the internal touchpad (tap-and-click, pinch and two finger scrolling). It stopped working about two weeks ago, after I've upgraded gnome to 3.20. Thank you for your assistance, anyway. it was worth to try ;) Best, S
Try to find out which kernel it worked with, because right now with how the kernel presents this device it cannot work with either libinput nor synaptics. You can easily check that by installing xf86-input-evdev and xf86-input-synaptics and removing xf86-input-libinput before restarting X.
Foud the solution in a logitech forum.. actually this keyboard has a known bug and the tap-an-click got randomly disabled when the device is waking up from idle status. To toggle tap-an-click I had to quick press "fn (function key) + left click button (on touchpad)". that's it! no problems with libinput actually. I've already got pinch to zoom and two finger scroll (horiz and vert) working and suspect that also the three finger tap or swipe is recognized because if I place three fingers on the thouchpad and try to swap, the cursor doesn't move. Thank you guys for your time! I am marking this as resolved S
