Elantech touchpad no tap-to-click

[sappur]

Hi,
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:

Touchpad does not work many times on boot

Hello I have been using Garuda, everything is excellent except that half the times I boot my laptop trackpad is disabled and the only way to fix it is to reboot completely. This issue used to occur on Manjaro too, however it was less seen there. inxi -Fzza System: Kernel: 5.10.15-120-tkg-bmq x86_64 bits: 64 compiler: gcc v: 10.2.1 parameters: intel_pstate=passive BOOT_IMAGE=/@/boot/vmlinuz-linux-tkg-bmq root=UUID=f2947d3f-0ce7-4b11-8892-ceb656679574 rw rootflags=s…

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

https://wiki.archlinux.org/title/Laptop#Elantech

(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"

    EndSection

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.

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

Also see(link given in archwiki)

What does the 'i8042.nomux=1' kernel option do during booting of Ubuntu?

https://bbs.archlinux.org/viewtopic.php?id=248740

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:

PrivateBin

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.

[sappur]

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:

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.
