Touchpad scroll speed is too high

I've searched on the internet how to slower touchpad two-finger scrolling.
My graphical environment is GNOME, but it has not needed option.
So, through terminal I tried next commands:

sudo libinput list-devices

gives:

sudo xinput list

gives:

And

sudo xinput list-props 8

gives:

I cant make touchpad scroll slower, I've tried to change

Coordinate Transformation Matrix, Velocity Scaling

I even created file

/etc/X11/xorg.conf.d/70-synaptics.conf

with properties

Section "InputClass"
    Identifier "touchpad"
    Driver "synaptics"
    MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "2"
        Option "EmulateTwoFingerMinZ" "20"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "30"
        Option "FingerHigh" "50"
        Option "MaxTapTime" "125"
	...
EndSection

Re: Touchpad scroll speed is too high

X.Org configuration files & xinput won't work under Wayland.

Looks like the Wayland GNOME desktop can't do this: https://gitlab.gnome.org/GNOME/gnome-co … issues/379

FWIW sway can use this in ~/.config/sway/config:

input <identifier> scroll_factor <floating point value>

See sway-input(5) for more on this.

And why are you running everything with sudo? That's a stupid thing to do.

I don't have ~/.config/sway/config file, even if I installed sway

Re: Touchpad scroll speed is too high

mkdir -p ~/.config/sway
cp {/etc/sway,$_}/config
vim $_ # other editors are available

I added to ~/.config/sway/config

input "2:14:SynPS/2_Synaptics_TouchPad" scroll_factor 0.5

But it didnt help.
Also, i have problems with sway socket path.

swaymsg -t get_inputs
00:00:00.025 [swaymsg/main.c:419] Unable to retrieve socket path
export SWAYSOCK=/run/user/$(id -u)/sway-ipc.$(id -u).$(pgrep -x sway).sock

env | fgrep SWAYSOCK
SWAYSOCK=/run/user/1000/sway-ipc.1000..sock

swaymsg -t get_inputs
00:00:00.000 [common/ipc-client.c:67] Unable to connect to /run/user/1000/sway-ipc.1000..sock

Re: Touchpad scroll speed is too high

Please post the entire config file.

FWIW you've added an extra "." (dot) to the SWAYSOCK variable but you shouldn't have to set that manually so also post exactly how you are launching sway.

This will start sway from a console screen and direct stdout & stderr to a log file (~/.sway.log) which can be shared here:

sway > ~/.sway.log 2>&1

Re: Touchpad scroll speed is too high

Hence, sway will only affect touchpad scroll speed?
