Bug#993733: libinput-bin: Thinkpad T470 trackpoint is too sensitive since 1.9.0
Package: libinput-bin
Version: 1.16.4-3
Severity: normal
Dear Maintainer,
Starting with libinput 1.9.0, the trackpoint on Thinkpad T470 is barely usable:
it is too sensitive and seems impossible to fine-tune using hw settings or
libinput accel speed setting.
A fix is to add a quirk with multiplier set to 0.4, same as for T480:
[Lenovo T470 Trackpoint]
MatchName=*TPPS/2 IBM TrackPoint
MatchDMIModalias=dmi:*svnLENOVO:*:pvrThinkPadT470:*
AttrTrackpointMultiplier=0.4
It is already merged upstream:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/680
With this quirk it is as good (or better) as with libinput 1.8.4. Sensitivity
feels the same as with 1.8.4 with the same hw settings for speed and sensitivity.
