Does anybody know how to increase the sensitivity of the Trackpoint on a Thinkpad X1 Carbon (5th generation) running with Ubuntu 17.10 Gnome on Wayland? I googled for it but all I found is that the input devices should be managed by libinput by default in this setup (Arch wiki). But the package libinput is even not installed on my machine.
Running
xinput list
gives:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ xwayland-pointer:13 id=6 [slave pointer (2)]
⎜ ↳ xwayland-relative-pointer:13 id=7 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ xwayland-keyboard:13 id=8 [slave keyboard (3)]
where the properties (xinput --list-props 6) look like:
Device 'xwayland-pointer:13':
Device Enabled (119): 1
Coordinate Transformation Matrix (121): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
Device Accel Profile (244): 0
Device Accel Constant Deceleration (245): 1.000000
Device Accel Adaptive Deceleration (246): 1.000000
Device Accel Velocity Scaling (247): 10.000000
Changing values doesn't seem to have an effect.
Xorg sessions are not an option, since I need fractional scaling for a high dpi screen.
In the case, that I have to install the package libinput, can anybody provide some information about what to change exactly? Since I'm new to Linux, I would happy to get explanations easy to follow for a beginner.
