После последнего обновления перестал работать тачпад

У меня есть lenovo z510, у которого есть сенсорная панель ALPS v7. После новой установки xubuntu 14.04 я использовал это исправление, чтобы оно заработало. Теперь, после последнего обновления ядра, оно больше не распознается.

    xinput
 ⎡ Virtual core pointer                     id=2    [master pointer  (3)]
 ⎜   ↳ Virtual core XTEST pointer               id=4    [slave       pointer       (2)]
 ⎜   ↳ Logitech USB-PS/2 Optical Mouse          id=11   [slave  pointer  (2)]
 ⎜   ↳ PS/2 Generic Mouse                       id=14   [slave       pointer  (2)]

Я все еще использую xubuntu 14.04, текущее ядро ​​3.16.0-60-generic x86_64

редактировать: ну, это выглядит странно
