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

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
