触摸板禁用

命令行键入xinput，查看touchpad设备ID，比如我的：

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜↳ Virtual core XTEST pointer               id=4    [slave  pointer  (2)]
⎜↳ Cypress APA Trackpad (cyapa)             id=14   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
↳ Power Button                              id=6    [slave  keyboard (3)]
↳ Video Bus                                 id=7    [slave  keyboard (3)]
↳ Power Button                              id=8    [slave  keyboard (3)]
↳ Sleep Button                              id=9    [slave  keyboard (3)]
↳ Sleep Button                              id=10   [slave  keyboard (3)]
↳ Integrated_Webcam_HD                      id=13   [slave  keyboard (3)]
↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]

可以看到触摸板的ID是14，那么接下来执行命令

xinput disable 14

即可禁用触摸板。如需恢复触摸板，执行命令

xinput enable 14
