Hi, after yesterday update, my touchpads scroll direction reverted back (naturalscrolling false)
based on here i added Option "NaturalScrolling" "true" to my libinput file but after rebooting, my system didn’t boot and stuck on message /dev/sda2: clean smthingfile/smthing ..... but i could use tty so i guess there was something wrong with my X ? (i should add that i had naturalscrolling before with this method)
here is my 40-libinput file 
GNU nano 5.8 40-libinput.conf
# Match on all types of devices but joysticks
#
# If you want to configure your devices, do not copy this file.
# Instead, use a config snippet that contains something like this:
#
# Section "InputClass"
# Identifier "something or other"
# MatchDriver "libinput"
#
# MatchIsTouchpad "on"
# ... other Match directives ...
# Option "someoption" "value"
# EndSection
#
# This applies the option any libinput device also matched by the other
# directives. See the xorg.conf(5) man page for more info on
# matching devices.
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 "NaturalScrolling" true
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
in tty mode, i commented out that option so my OS can boot without issues
