如何設置觸摸板多指點擊功能?


10

我正嘗試通過以下方式設置多指水龍頭:

  • 單指-左鍵
  • 兩根手指-中鍵
  • 三個手指-右鍵單擊

我目前擁有的是:

  • 單指-左鍵
  • 兩根手指-右鍵單擊
  • 三根手指-無

我已經在Ask Ubuntu上找到了幾個問題,以及關於該主題的Ubuntu Wiki(以及一些常規的Google搜索),但是找不到任何幫助我的東西。我知道xinput,但是我不知道該在那裡進行更改以及如何進行更改。

如果有人能指出我正確的方向,我將不勝感激,並給他25個閃亮的代表點,一個大的綠色勾號和一些cookie。

This can be done using synclient.

To do this per-session (and to test that it's working correctly on your system), type into a terminal the following commands:

synclient "TapButton2"=2
synclient "TapButton3"=3

The option TapButtonx means "A tap with x fingers, not in a corner", while the numbers 1, 2 and 3 after correspond to left, middle and right click respectively.

To make these changes permanent, navigate to /usr/share/X11/xorg.conf.d. ls to find the file with "synaptics.conf" in the name (in my case, 50-synaptics.conf). Then, sudo gedit 50-synaptics.conf, and add the following lines into the end of the first InputClass section:

Option "TapButton2" "2"
Option "TapButton3" "3"

Then restart your machine, and you should be good to go.

If editing the 50-synaptics.conf file doesn't work, do the following: open dconf-editor and navigate to org/gnome/settings-daemon/plugins/mouse. Uncheck the box marked "active" and restart again. This will allow the synaptics settings to take precedence.

Here is what we need to do:

  1. First we gather the ID for the trackpad/mouse pad.

    $ xinput --list  
    Virtual core pointer                        id=2    [master pointer  (3)]  
    ⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]  
    ⎜   ↳ PS/2 Generic Mouse                        id=10   [slave  pointer  (2)]    
    **⎜   ↳ SynPS/2 Synaptics TouchPad                  id=11   [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)]    
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]    
    ↳ AT Translated Set 2 keyboard              id=9    [slave  keyboard (3)]    
    ↳ HP WMI hotkeys                            id=12   [slave  keyboard (3)]    
    
  2. Now the highlighted one is our device with ID in my case 11

  3. List out the properties and hence configuring the one against the ID

    $ xinput --list-props 11

  4. Now find the point, in this case its 285, 288. Using the command you may configure the same on your touch pad.

    $xinput set-int-prop <properties>  
    
  5. Hope this helps
