MX Master mouse too sensitive in Ubuntu

Question

I have a Logitech MX Master mouse (bluetooth) and Ubuntu 17.04.

The mouse is fine with Windows but I find it too jumpy in Ubuntu, and can be trick clicking on into the right place in text and links.

I tried changing the pointer speed in the mouse & trackpad control panel but it makes no difference.

I tried 'xinput list-props' for the input device and got a list but none seemed to be of any use.

Is there any way I can fine tune the mouse?

You can adjust cursor sensitivity by altering value of libinput Accel Speed property, as it accepts values between -1 to 1 (incl. decimal places).

Find the ID of your mouse (which I believe you already did as you ran xinput list-props) using xinput --list --short, you'll see output similar to following;

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=16   [slave  pointer  (2)]
⎜   ↳ Logitech MX Master                        id=12   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ HP Wide Vision HD                         id=13   [slave  keyboard (3)]
    ↳ Yubico Yubikey 4 OTP+U2F+CCID             id=14   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]
    ↳ HP Wireless hotkeys                       id=17   [slave  keyboard (3)]
    ↳ HP WMI hotkeys                            id=18   [slave  keyboard (3)]
    ↳ Dell KB216 Wired Keyboard                 id=10   [slave  keyboard (3)]
    ↳ Dell KB216 Wired Keyboard                 id=11   [slave  keyboard (3)]
    ↳ Logitech MX Master                        id=19   [slave  keyboard (3)]

In my case, ID for MX Master mouse is 12. Once you have the ID, run following.

xinput --set-prop 12 "libinput Accel Speed" -0.6

Replace 12 with ID of your Mouse that you found earlier, and change -0.6 to any value that suites to your liking.

Remember that these changes are not preserved across restarts and logins, you'll need to create shell script like following;

#!/bin/bash
xinput --set-prop 12 "libinput Accel Speed" -0.6

And save it to your Home folder as fixmouse.sh, and then open terminal in home folder and run chmod +x fixmouse.sh.

Now run gnome-session-properties in terminal to open Startup Applications GUI, and add the script you just created to the list.
