1.使用xinput list查看与触摸板相关的id,以下是本机的输出，没搞清楚为什么是Mouse!!!
jello@jello:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ HID compliant-mouse HID compliant-mouse id=11 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse 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)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ Sleep Button id=10 [slave keyboard (3)]
↳ Integrated Webcam id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
↳ Dell WMI hotkeys id=16 [slave keyboard (3)]
2.从第一步可以得到触摸板的id=14,那本机上
2.1:禁止触摸板
xinput disable 14
2.2恢复触摸板
xinput enable 14
！！！不足之处欢迎纠正！！！
