I have Thinkpad T440, which do not ship with the three buttons on the touchpad.

I used to use trackpoint with clicks on those three buttons. While in this T440 case, I want to disable the touchpad " MOVE | tap-to-click | two-finger or three-finger " features, and only config it like a big clickable buttons, with the middle one.

Can anyone tell me how to write it in /usr/share/X11/xorg.conf.d/

I have those files:

10-evdev.conf             11-evdev-trackpoint.conf  50-wacom.conf
10-quirks.conf            50-synaptics.conf         51-synaptics-quirks.conf
11-evdev-quirks.conf      50-vmmouse.conf       

Thanks in advance.

  • I'm not quite sure what you're asking here. May 5, 2015 at 1:26
  • I want to disable trackpad but with left right and middle "button" abled

  • Ah. Now that's possible, but a little tricky. Run xinput list in a terminal and edit the output into your answer. May 5, 2015 at 10:04
  • I read the archlinux doc for it, but still confused about it. Do anyone have some examples?

  • Just run that command and I'll tell you what to do. May 5, 2015 at 23:55

Well, this is not the direct answer, but a suggestion and examples. If you run xinput, you will get list of your devices. Then run xinput list-props $id where $id is your touchpad id in the list.

You will have a list of options like this:

$ xinput list-props 13
Device 'SynPS/2 Synaptics TouchPad':
    Device Enabled (135):   1
    Coordinate Transformation Matrix (137): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
    Device Accel Profile (268): 1
    Device Accel Constant Deceleration (269):   2.500000
    Device Accel Adaptive Deceleration (270):   1.000000
    Device Accel Velocity Scaling (271):    12.500000
    Synaptics Edges (292):  1765, 5371, 1637, 4453
    Synaptics Finger (293): 25, 30, 0
    Synaptics Tap Time (294):   180
    Synaptics Tap Move (295):   234
    Synaptics Tap Durations (296):  180, 180, 100
    Synaptics ClickPad (297):   1

You can change all of these on-the-fly with xinput set-prop $id $propId $value where $id is the device id, $propId is property id in brackets and $value is what you want it to be. For example:

xinput set-prop 13 135 0 sets Device Enabled (135) to 0 and this will disable the touchpad.

You will need descriptions of properties and a way to make your changes permanent. Descriptions can be found in man synaptics, but wait, they are in another cryptic format! Let's see why.

To make changes permanent, you need to create conf file in /etc/X11/xorg.conf.d, for example 30-tochpad.conf with contents like these:

    Section "InputClass"  # you can read more in `man xorg`
            Identifier "all touchpads"  # just a name for this config
            MatchIsTouchpad "on"  # enables this config for all detected touchpads
            Driver "synaptics"  # enables synaptics-specific options below

            # This will disable the device
            #Option "Ignore" "1"

            # There are options that are generic for input-devices or mouse-like devices, see `man evdev`:
            Option "ButtonMapping" "0 0 0 0 0 0 0"  # i disabled all buttons here, for example

            # Here go options from `man synaptics`
            Option "VertTwoFingerScroll" "1"
            Option "HorizTwoFingerScroll" "1"
            Option "PalmDetect" "1"
            Option "ClickPad" "0"                
            # ...etc...

So, man synaptics describes options for xorg.conf and tells how they correspond to xinput list-props output.

PS. I tried to configure trackpoint on my ThinkPad X220 to have only two-fingers-scroll enabled, without clicks or mouse movement. I failed. Maybe you will manage to do what you want (there was an option to disable everything but clicks, maybe Synaptics Off).

Alternatively You could download the "GnomeTweakTool" and configure or deactivate it under Mouse&Keyboard > Click Emulation.
