           Summary: Touchpad - Edge scrolling and two finger scrolling
                    enabled simultaneously - Plus tap to click
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput

Hi,

For my touchpad, when using libinput it seems both scrolling methods work
simultaneously even when not really enabled.

Let me clarify this. In GNOME settings I do not have two-finger scrolling
enabled however both two-finger scrolling and side-scrolling work at the same
time. I can use either one. Then, if I enable two-finger scrolling, only
two-finger scrolling works (and edge scrolling stops working).

So within the GNOME settings, when checking:

Two finger scroll: I get two finger scroll

When unchecking:

Two finger scroll: I get two finger scroll + side scroll

Any ideas why that happens?

xinput 
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]

xinput list-props 11

At the same time, while tap to click works in GNOME, I can't get it to work on
GDM. Once in GNOME, tap to click works as expected. I assumed adding this to
/etc/X11/xorg.conf.d/99-libinput.conf would do the job but tap to click does
not work still. Any ideas on this too?

Section "InputClass"
        Identifier "enable tapping and edge scrolling"
        MatchDriver "libinput"
        Option "ScrollMethod" "edge"
        Option "Tapping" "on"
EndSection

Thanks!
