<pre>My TrackPoint also started to behave very differently after installing libinput
1.9.3. I'm using a ThinkPad X121e running Arch Linux. Using sysfs to change
the sensitivity worked.
Locate the files we can change (command from
<<a href="https://gist.github.com/noromanba/11261595">https://gist.github.com/noromanba/11261595</a>>):
$ find /sys/devices/platform/i8042 -name name | xargs grep -Fl TrackPoint |
sed 's/\/input\/input[0-9]*\/name$//'
/sys/devices/platform/i8042/serio4/serio5
I checked whether the upgrade changed any values at this point, which it
didn't:
# for f in /sys/devices/platform/i8042/serio4/serio5/*; do [[ -f $f ]] &&
echo "$f" && cat "$f"; done > new-values.txt
# pacman -U /var/cache/pacman/pkg/libinput-1.8.3-1-x86_64.pkg.tar.xz #
downgrade libinput
# systemctl reboot
# for f in /sys/devices/platform/i8042/serio4/serio5/*; do [[ -f $f ]] &&
echo "$f" && cat "$f"; done > old-values.txt
$ diff -s new-values.txt old-values.txt
Files old-values.txt and new-values.txt are identical
In the end I changed /sys/devices/platform/i8042/serio4/serio5/sensitivity to a
lower value:
$ cat /sys/devices/platform/i8042/serio4/serio5/{speed,sensitivity}
97
128
$ echo 100 | sudo tee /sys/devices/platform/i8042/serio4/serio5/sensitivity</pre>
