can't change sensitivity on (new) Alps trackstick

[Michael]

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.

Tries the mainline kernel - no change.

Btw, I set the acceleration in the system settings already to max - but it's still too slow.

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.
