Description Boyan Ding 2017-02-10 10:08:25 UTC

The touchpad on my newly bought Acer VX5-591G-72LY is not recognized by libinput as a touchpad, but only as pointer device instead.

The system is Arch Linux running kernel 4.9.8-1-ARCH with libinput 1.6.1.

Looking at the Xorg log, libinput correctly detected it as a touchpad, it seems the problem originate from some improper permission settings, after fixing the problem, I could configure it in gnome's input settings.

But I have a question now, the touchpad of this laptop is without button and unclickable, but libinput disable tap-to-click by default, is it the intended behavior?

libinput detected it as clickpad, you should be able to press the touchpad itself to trigger a physical click. is this not correct? https://wayland.freedesktop.org/libinput/doc/latest/touchpads.html

we only enable tap by default on touchpads that are truly without buttons (like wacom tablets for example).

It is actually clickable, just found it when pressing the edge. Sorry for the noise.
