Description groucho 2017-04-09 13:14:53 UTC

Hi,
I have tested Debian 9 Gnome and Fedora 25 (both have libinput 1.6.3) on a Thinkpad X201 and have found that the trackpoint is a little slow (I would say half the speed compared to evdev).

As a workaround, I have edited /etc/udev/hwdb.d/71-trackpoint.hwdb with these settings :

evdev:name:TPPS/2 IBM TrackPoint:dmi:bvn*:bvr*:bd*:svnLENOVO:pn*:pvrThinkPadX20*:*

POINTINGSTICK_SENSITIVITY=200
POINTINGSTICK_CONST_ACCEL=1.25

I guess that's a plain X201, not a X201s or so? what does /sys/class/dmi/id/modalias say?

Comment 2 groucho 2017-05-09 10:57:06 UTC

Yes, just a X201, with a trackpoint and no trackpad.
