i am not sure what package is causing the problem. Ubuntu wiki tells me that choosing the 'kernel' is a safely bet. But i still don't know which kernel package it is. The editing web-page told me there's too much packages about kernel. So I fill the name 'input-wacom'. If some triagers or developers see this bug-report, please check it and choose a right package for me. Thanks!
