Comment 13 for bug 1758023

I have had this same problem since upgrading to 18.04, and it has been infuriating, as the defaults greatly impact my ability to perform my work. I'm going to have to switch distros (planning for Solus) if this does not get fixed. Additionally, Lagoda's solution (in #10) did not work at all for me.

I have done all of the following both after removing libinput via 'sudo apt remove xserver-xorg-input-libinput' and after re-installing it, and there was no difference in any of the behaviors.

I have been able to verify that changing the sliders for acceleration and sensitivity change the values displayed by 'xinput --get-feedbacks 13' (13 being my pointer device, as discovered via 'xinput --list'). However, there is no difference in mouse movement whatsoever, even between all 4 extreme min/max combination settings. However, I have been able to change the acceleration via 'xinput --set-prop 13 "libinput Accel Speed" x', where x can be between -1 and 1, and I am both able to definitely notice the dramatic change in acceleration, and the change in the value reported via 'xinput list-props 13'.

However, without being able to change the sensitivity, I still have issues performing my work.

There was no need to install evdev on my machine, as in Lagoda's solution (in #10), as it was already installed.
