Tapping isn't something that the kernel handles, it's all in userspace - libinput or xf86-input-synaptics usually. I suggest reproducing the issue with libinput debug-events and going through the list here: https://wayland.freedesktop.org/libinput/doc/latest/reporting-bugs.html Cheers, Peter > I thought, that could be hid input module issue but not an X11 or > display environment issue, because by not touching any other > component, but just altering the kernel, the problem can be > reproduced.
