Title:
can't change sensitivity on (new) Alps trackstick
Status in linux package in Ubuntu:
Confirmed
Bug description:
On a Toshiba z20t using Ubuntu 16.04, I can't change the sensitivity
via
echo 200 | sudo tee /sys/devices/platform/i8042/serio1/serio2/sensitivity
echo 150 | sudo tee /sys/devices/platform/i8042/serio1/serio2/speed
echo 1 | sudo tee /sys/devices/platform/i8042/serio1/serio2/press_to_select
as pointed out in https://wiki.ubuntuusers.de/Trackpoint/, because
these virtual files are missing.
