Touchpad tap doesn't work on a newly installed archlinux based garuda lxqt desktop

jozmak · 10-19-2020, 06:40 PM

Hello,
I've just installed garuda lxqt desktop and the touchpad tapping feature doesn't work. Earlier, when I faced similar problem I just created a 40-libinput.conf or a 40-touchpad.conf file and copied them in the /etc/X11/xorg.conf.d folder and everything was fine. But this time this trick doesn't work. I searched google and I found that touchpad malfunction is common among arch based distros. But I couldn't find any solution to the problem. Help would be greatly appreciated.

Here are some hardware info:

Thanks for replying.
I am not an expert on those issues that's for sure.
I read the archwiki touchpad entry but I couldn't find any solution to the problem by following those instructions. What confuses me is that the touchpad partially works, for instance the scroll, and the left click work. Only the one finger and the two finger taps don't work.
The other thing is that on a separate partition I have a gnome desktop installed (Manjaro). Gnome always works out of the box, it never gave me any touchpad problem. Only minor desktops like lxqt, budgie and the likes that don't work.

Where is this ellipsized output from?

You will have to work your way through that ArchWiki article.
It contains important hints.

FWIW, I'm using the (now superseded) synaptics driver for my touchpad, not libinput.

The above is the output of "libinput list-devices" command
I read the touchpad and libinput wikis but I found no solution to the problem there.
This is a longstanding issue with my laptop but as I said before I always solved it by creating and copying a 30-touchpad.conf file in the "/etc/X11/xorg.conf.d" folder as described in archwiki.
I also noticed that if the distro uses wayland as a display server I don't have touchpad problem. The touchpad in Gnome and Wayfire always work out of the box. Only minor distros with xorg based display server where this problem occurs.
I tried synaptics as described in the wiki. I installed "xf86-input-synaptics" created a 70-synaptics.conf file as described in the wiki, I rebooted and the system hanged.

OK.
Assuming you go back to where you were when you started this thread, "libinput list-devices" tells you that Tap-to-click is disabled (you did notice my highlight there?).
Try to tell it to enable it.

I noticed that and that's why I created a 40-libinput.conf file in the /etc/X11/xorg.conf.d directory enablig tapping as suggested in archwiki. However, the file is not recognized by some reason.

Take a look at may 40-libinput.conf file. Tapping enabled. Yet the libinput list-devices command doesn't register the change.

Code:

Section "InputClass"
        Identifier "libinput pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
Option "AccelSpeed" "-0.8"
	Option "ClickMethod" "clickfinger"
	Option "DisableWhileTyping" "True"
	Option "NaturalScrolling" "True"
	Option "Tapping" "True"
        Option "TappingDrag" "on"
        Option "HorizontalScrolling" "False"
EndSection

Section "InputClass"
        Identifier "libinput touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Section "InputClass"
        Identifier "libinput tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

Please clean that file up, there's duplicate sections.

Also, according to ArchWiki, it should be
"Tapping" "on"
and not
"Tapping" "True"
???

I changed it to "on" but it has no effect.

Hm.
Show us the Xorg.0.log of the current session. All of it.

I know there is site where I can post long text files, but I can't recall its name. Can anyone tell me the name of that site because the Xorg.0.log file is too long to post it here - this forum prevented me to post it.

If you clear the Xorg.0.log file, then reboot it will be much smaller and only include the current session, which is what was asked for.

The site is called Linux Questions and the functionality is called Attachments.

Below the posting area you'll find a "Manage Attachments" button which allows you to upload files, including log files that are too long to include directly in the post content.
