[SOLVED] libinput and synaptics conflict

I am trying to enable vertical two finger scrolling in GNOME. I edit 70-synaptics.conf file to allow for it.

 cat /etc/X11/xorg.conf.d/70-synaptics.conf 
# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# DO NOT EDIT THIS FILE, your distribution will likely overwrite
# it when updating. Copy (and rename) this file into
# /etc/X11/xorg.conf.d first.
# Additional options may be added in the form of
#   Option "OptionName" "value"
#
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
        MatchDevicePath "/dev/input/event*"
	Option "VertTwoFingerScroll" "True"
EndSection

However it is not working. When I try using synclient I get this.

synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?

I read in the wiki that wayland uses libinput however these are devices using that driver

grep -e "Using input driver 'libinput'" /var/log/Xorg.0.log

However the Xorg log looks like it trying to use both

xinput is not seeing synaptics as well

Am I stuck with libinput while using Wayland instad of synaptics?

Re: [SOLVED] libinput and synaptics conflict

Your post did not make it sure if you are using Wayland or X.org, but on Wayland only libinput is used. And also when on X.org running Gnome, the Gnome settings only support libinput. So my suggestion would be to uninstall synaptics to avoid any conflicts and use libinput exclusively. You can enable two-finger scrolling in Gnome settings.

Re: [SOLVED] libinput and synaptics conflict

I was trying both Wayland and Xorg. I uninstalled xf86-input-synaptics and reboooted. Xorg.0.log still sees synaptics driver as loading. What am I missing?

Re: [SOLVED] libinput and synaptics conflict

That's strange, what does

pacman -Qo /usr/lib/xorg/modules/input/synaptics_drv.so

show? Does /usr/lib/xorg/modules/input/synaptics_drv.so really still exist?

Perhaps you are looking at an old X log file? Check the date of files in /var/log to make sure you are looking at a new file.

Re: [SOLVED] libinput and synaptics conflict

Following from Ropid's point, xorg logs have not been stored in /var/log for quite some time - that is likely a *very* old log.

No the driver is not there.

Ropid was right the Xorg.0.log was old. Journalctl gave more accurate information

Re: [SOLVED] libinput and synaptics conflict

I found the issue! The  libinput page in wiki mentioned towards the end to add the boot parameters if your touchpad is not detected.

i8042.noloop i8042.nomux i8042.nopnp i8042.reset

I did that rebooted and now my touchpadis working and I can manage via gnome settings! Marking as solved.
