Finally decided to try to get libinput to work

Timothy Miller · 12-28-2017, 01:00 PM

So had this laptop a while, have never gotten libinput to work sufficiently on it. Synaptics has always worked well, but given that it's depracated going forward, I'd like to get off of using it.

So today I switched back to libinput, and gotten most everything working. All physical buttons work, tapping is now enabled, and it works with single finger and 2-finger tapping (right click). 3-finger tapping is however doing the same as 2-finger, not middle clicking.

I know the hardware supports it, with synaptics it works fine, and has for years.

Here's my /etc/X11/xorg.conf.d/40-libinput.conf

Code:

Section "InputClass"
        Identifier      "AlpsPS/2 ALPS DualPoint Touchpad"
        MatchIsTouchpad "on"
        Driver          "libinput"
        Option "Tapping" "on"
        Option "TappingButtonMap" "lrm"
EndSection

xinput list

Code:

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

Props for the touchpad:

I've tired lmr and lrm both for TappingButtonMap, but neither affected anything.

Any ideas on what I'm doing wrong, or is this just going to be that I'm stuck on the outdated Synaptics for eternity?

Try debug-events to see what you are actually getting. Maybe you are missing some initialization.

Never seen that before, will have to try. Thanks, will post back once I get the chance.

Do these tools ONLY work with Wayland? Because they not liking me:

Code:

tim@wildmage:~$ sudo libinput debug-gui
libinput: debug-gui is not a libinput command or not installed. See 'libinput --help'
tim@wildmage:~$ sudo libinput debug-events --enable-tapping --set-click-method=clickfinger
libinput-debug-events: unrecognized option '--enable-tapping'

tim@wildmage:~$ apt list --installed | grep libinput
