It is possible that you i.e. Fedora installed "xorg-x11-drv-libinput"
with its configuration file:

/usr/share/X11/xorg.conf.d/90-libinput.conf 
# Match on all types of devices but tablet devices and 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
..

So if you do not explicitly define 'evdev' as "input driver" driver,
'libinput' as another "input driver" will "steal" focus on "mouse".

'libinput' as "input driver" is actually intended for Wayland - a simpler replacement for X,
although it can be used as *very* basic "input driver" for X also.

http://wayland.freedesktop.org

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are running the Xfce on top of the X, thus *not* the Wayland,
you really do not need 'libinput', so you can safely:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# yum erase xorg-x11-drv-libinput

Thereafter your configuration file
i.e.
/etc/X11/xorg.conf.d/10-evdev.conf
would no longer need the line:
Driver "evdev"

KEYBOARD
       The  Xorg  server is normally configured to recognize various special combinations
       of key presses that instruct the server to perform some action, rather  than  just
       sending  the  key press event to a client application. These actions depend on the
       XKB keymap loaded by a particular keyboard device and may or may not be  available
       on a given configuration.

       The following key combinations are commonly part of the default XKEYBOARD keymap.

       Ctrl+Alt+Backspace
               Immediately  kills the server -- no questions asked. It can be disabled by
               setting the DontZap xorg.conf(5) file option to a TRUE value.

               It should be noted that  zapping  is  triggered  by  the  Terminate_Server
               action in the keyboard map. This action is not part of the default keymaps
               but can be enabled with the XKB option "terminate:ctrl_alt_bksp".
..

If this option is needed but not enabled by configuration

# localectl set-x11-keymap "" "" "" terminate:ctrl_alt_bksp

will (re)create the required configuration file i.e.

/etc/X11/xorg.conf.d/00-keyboard.conf
Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

$ man 1 localectl

Yes, that was the default "mouse" movement physics, several versions back, Xorg versions.

Bob, you have understood what the libinput developer does not seem to be understood! ;)

'VelocityScale' equivalent in libinput
