Elantech touchpad no tap-to-click

I have (I think) solved an issue where my touchpad would sometimes not respond on boot, but now I have lost tap-to-click and I don't know why.

I have tried the solutions in this post:

I have also created /etc/modprobe.d/psmouse.conf as recommended in:


(however, I did not check the journalctl for that entry before trying it, so maybe I should delete it since it didn't solve the problem either way).

It is relevant that I unsuccessfully tried to give myself tap-to-click functionality according to this:

Enable tap-to-click on Arch Linux | xtrymind (and others)

and as a result, I have edited /etc/X11/xorg.conf/30-touchpad.conf so that it currently says

    Section "InputClass" 

            Identifier "libinput touchpad catchall" 

            Driver "libinput" 

            MatchIsTouchpad "on" 
            MatchDevicePath "/dev/input/event"

            Option "Tapping" "on" 
#            Option "TappingDrag" "on"
#            Option "AccelProfile" "linear" 
#            Option "AccelSpeed" "0.4" 

            Option "TappingButtonMap" "lmr" 

            Option "ClickMethod" "buttonareas"


I have had several other blocks of text inside this file, but nothing gives me tap-to-click. This makes me think that it's being controlled by some other driver, even though I have tried to disable it via modprobe as in the Arch Wiki above.

Not sure where to go next.

Did you tried lts-kernel?
And you are using libinput right?

Also see(link given in archwiki)


Hope these links help you.

I am using linux-lts and libinput, yes. And I have the /etc/modprobe.d/elan.conf file with a line that says elantech_smbus=0 synaptics_intertouch=0
This has not solved the issue with the mouse occasionally not working, and it has also not solved the issue of tap-to-click going away.

Here's my journalctl for a recent boot where the mouse didn't work again:

This line worries me:

Sep 04 12:46:50 sappur-nitroan51542 modprobe[356]: libkmod: kmod_config_parse: /etc/modprobe.d/elan.conf line 1: ignoring bad line starting with 'elantech_smbus=0'

So I will change the elan.conf file to say options psmouse elantech_smbus=0 instead and see if that does anything different on the next boot.

I have rebooted and the mouse still has no tap-to-click like it did before, but I can't know if it fixed the other issue for sure. The journal no longer has the bit about a "bad line" so that's a good sign.

It still hasn't worked, but I have an update. If I try to put on tapping using

xinput set-prop "ELAN0504:01 04F3:3091 Touchpad" "libinput Tapping Enabled" 1

it gives me an error that tapping isn't a recognized property:

 property 'libinput Tapping Enabled' doesn't exist, you need to specify its type and format 

This happens whether I do "tapping on" or "tapping enabled" or even "tapping true"

When I do xinput list-props "ELAN0504:01 04F3:3091 Touchpad"
it gives me this list:

	Device Product ID (277):	1267, 12433

So I have googled around for the 325: "Synaptics Tap Action" but I have no idea how to modify this besides by trial and error.

EDIT: I HAVE SOLVED IT! I used trial and error on the xinput command. For any else with this issue, the command I used was

xinput set-prop "ELAN0504:01 04F3:3091 Touchpad" "Synaptics Tap Action" 0, 0, 0, 0, 1, 0, 0

So the 5th 0 should be changed to 1

Guess what. I also just learned that I never uninstalled xf86-input-synaptics. I have uninstalled that and changed the conf file above to what I had before and now it's working again. Geez.
