Inconsistent behavior for Mouse Natural Scrolling

So it looks like I am using evdev. And unless I am misunderstanding your previous note, I shouldn't be using evdev. Is that correct?

Yes, I think you'd get better behaviour with libinput. I'm surprised that 'xserver-xorg-input-libinput' doesn't provide /etc/X11/xorg.conf.d/40-libinput.conf (or similar) as it does with other distros.

For example, my install (openSUSE Leap 15.0) has 40-libinput.conf with the following...

Code:

# Match on all types of devices but joysticks
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 "Tapping" "On"
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

You could create this file manually, then restart the X-server (or just reboot), and check that libinput is now handling the mouse etc.

Not sure that is appropriate for Xfce 4.12 on Debian Stable. This comment from Dolphin_Oracle may be of interest:

We actually added the 10-evdev.conf during MX-17 development to fix the otherwise non-functional mouse acceleration settings in Xfce-mouse-settings.

We looked at libinput and it is installed, but the 10-evdev.conf file probably forces use of the evdev drivers. The Xfce mouse settings (at least under our version from Debian) do not work very well with libinput (wheel settings could not be changed at all in some cases). Maybe that will be different in Buster.

That may be the case but for natural scrolling I still think it's worth a shot, and just use libinput CLI to adjust the mouse (if there are problems with configuring via the DE).

I will give it a shot over the weekend. Probably Sunday. I've got tons of work and kid shuffling stuff going on Friday/Friday night and Saturday.

[edit]

Since my libinput version is 0.23.0-2, should the file be named differently, like 23-libinput.conf? Or does the version have nothing to do with the file name?

The version has nothing to do with it. Just an ordering process used by Xorg to determine precedence.

Well I'll be a... It worked!

So far every app I have tried scrolls "naturally."

Thank you everyone for your input (ha ha)!

So I created 40-libinput.conf, I edited 10-evdev.conf and commented out the mouse section, added a mouse section into libinput with the extra natural scroll option and rebooted. So far so good.

As I expected it would. There should have been no need to explicitly edit the 10-evdev.conf file though. The X-server should apply the directives from 40-libinput by precedence. Anyway, good to read that natural scrolling is now working for you.

I fixed mine by going into settings and selecting "mouse and touchpad" and then click > touchpad > scrolling mode > two-finger scrolling.
