I'm using Xubuntu 15.10 on a Lenovo Thinkpad Twist (S230u).
Unfortunately, the trackpoint device (the red stick between the g/h/b keys replacing the mouse) is not recognized by Ubuntu - most of the time.
Every once in a while the device works just perfectly. When this happens, there is an entry under
Settings / Mouse and Touchpad / Device : **TPPS/2 IBM TrackPoint**
But after the next reboot this entry will have disappeared and the device won't work.
Does anyone have an idea what causes this strange behavior ?
Thanks !
