--- Comment #29 from Martin Wilck ---
The POINTINGSTICK_CONST_ACCEL trick ceased to work with libinput 1.9.
See https://bugs.freedesktop.org/show_bug.cgi?id=106323 for technical
background. Once this bug is solved, there'll probably be a better solution for
recent libinput versions, too.
Update on possible workarounds, other than falling back from the ALPS driver to
the generic PS/2 driver:
Solution 1: Use evdev
Under X, use the evdev input driver, and set the ConstantDeceleration property
to 8 or more.
# cat >/etc/X11/xorg.conf.d/60-alps.conf </etc/udev/rules.d/80-libinput.rules <= 1.9
With libinput 1.9 and higher (SLE15, Tumbleweed), set
LIBINPUT_ATTR_TRACKPOINT_RANGE to the maximum value 100:
# cat >/etc/udev/rules.d/80-libinput.rules <
