ubuntu多點觸控
通過xinput 設置
先確定 筆記本的硬件
$xinput list
我的輸出結果如下：
root@terminus-K40AF:/usr/local/soft# xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=13 [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)]
↳ USB 2.0 Camera id=10 [slave keyboard (3)]
↳ Asus Laptop extra buttons id=11 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
TouchPad的名稱是"ETPS/2 Elantech Touchpad"
接下來，我們操作如下：
1
xinput set-int-prop "ETPS/2 Elantech Touchpad" "Two-Finger Scrolling" 8 1
2
xinput set-int-prop "ETPS/2 Elantech Touchpad" "Synaptics Two-Finger Scrolling" 8 1 1
3
xinput set-int-prop "ETPS/2 Elantech Touchpad" "Synaptics Two-Finger Pressure" 32 10
4
xinput set-int-prop "ETPS/2 Elantech Touchpad" "Synaptics Two-Finger Width" 32 8
可以編寫成shell腳本，放入啟動變量中 /etc/rc.local中
1
#!/bin/bash

3
xinput set-int-prop "ETPS/2 Elantech Touchpad" "Two-Finger Scrolling" 8 1
