Как починить сенсорную панель (synaptics) проблема на acer aspire v 13? Иногда курсор переходит как сумасшедший

Иногда курсор запускает переход тут и там (очень быстро). Отключение и включение сенсорной панели помогают, но в течение короткого времени.

xubuntu 15.04, 3.19.0-30-универсальный

"список xinput" показывает, что базовый указатель НЕИЗВЕСТЕН

user@laptop:~$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse                id=11   [slave  pointer  (2)]
⎜   ↳ SYN1B7F:00 06CB:2991 UNKNOWN              id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
---

Есть ли что-то, что я могу сделать?
