Whether it shows up reallys depends on your system. Especially when there's multiple mouse driver available and you may using evdev. For example, here's one output on my system, when you see something like this, you'll know it's using libinput's xf86 driver. On ubuntu the relavant package I found is: https://packages.ubuntu.com/artful/xserver-xorg-input-libinput $ xinput list-props 16 Device 'Newmen1100 MOUSE': Device Enabled (142): 1 Coordinate Transformation Matrix (144): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Natural Scrolling Enabled (285): 0 libinput Natural Scrolling Enabled Default (286): 0 libinput Left Handed Enabled (287): 0 libinput Left Handed Enabled Default (288): 0 libinput Accel Speed (289): 0.000000 libinput Accel Speed Default (290): 0.000000 libinput Accel Profiles Available (435): 1, 1 libinput Accel Profile Enabled (436): 1, 0 libinput Accel Profile Enabled Default (437): 1, 0 libinput Scroll Methods Available (291): 0, 0, 1 libinput Scroll Method Enabled (292): 0, 0, 0 libinput Scroll Method Enabled Default (293): 0, 0, 0 libinput Button Scrolling Button (438): 2 libinput Button Scrolling Button Default (439): 2 libinput Middle Emulation Enabled (297): 0 libinput Middle Emulation Enabled Default (298): 0 libinput Send Events Modes Available (262): 1, 0 libinput Send Events Mode Enabled (263): 0, 0 libinput Send Events Mode Enabled Default (264): 0, 0 Device Node (265): "/dev/input/event17" Device Product ID (266): 7119, 41 libinput Drag Lock Buttons (301): <no items> libinput Horizontal Scroll Enabled (302): 1 REPOSITORY R119 Plasma Desktop REVISION DETAIL https://phabricator.kde.org/D8798 To: xuetianweng, ngraham, #plasma, jriddell Cc: jriddell, apol, rkflx, plasma-devel, ZrenBot, progwolff, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, mart
