i cant get two finger scrolling to work. tried everything i found in the internet i.e installed xf86-input-synaptics and copied usr/shared/X11/xorg.conf.d/70-synaptics.conf to etc/X11/xorg.conf.d/20-synaptics.conf
and it has next lines in it
# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on

EndSectiongot gpointing-device-settings and tried to switch on two finger scrolling in it, everytime i click vertical two finger scrolling the program closes itself and when i reopen it has vertical two finger scrolling enabled but it's still not working.
All of these actions I did after I had no success enabling two fingers scrolling in default libinput, the option to enabling it was in gnome touchpad settings. And by the way today I noticed the option for two finger scrolling disappeared from the settings. maybe because i updated kernel today.
I have following output from synclient

tried everything i found in the internet
But it appears that didn't include reading the Arch Wiki on Synaptics and its red warning box right at the top:
Warning: xf86-input-synaptics is no longer actively updated. If possible, use libinput.
I'd recommend using libinput (there's an Arch Wiki page dedicated to it) and its configuration.

well i switched to libinput, removed synaptics (again)
and then ran next commands

libinput Scroll Methods Available (289): 0, 1, 0means touchpad has only edge scrolling, which is not true, I can two-finger scroll in windows. the first digit should be 1 for two finger scrolling, libinput driver doesn't understand the touchpad abilitiy. how can I fix this?

personally i just do it the easy way.
download gnome-tweaks
go to the keyboard and mouse section
click on "area" in mouse click emulation
its the easy way for two finger scrolling on trackpad
