How to configure the touchpad middle click?

You can make it work and persist in Ubuntu 12.04, even afer suspending, following these steps.

First, create a file with your script:

echo synclient TapButton3=2 > ~/touchpad_settings.sh

(You could place the script in another directory, e.g. /usr/bin or /etc, if you wanted it to be in a more "generic" place, in case you have multiple accounts in your ubuntu installation.)

Then make it executable:

chmod +x ~/touchpad_settings.sh

And finally, run the following command replacing "user" with your user name:

gsettings set org.gnome.settings-daemon.peripherals.input-devices hotplug-command "/home/user/touchpad_settings.sh"

Then reboot, or logout & login, or restart GNOME.

That's all!

I was searching for this and I found out that the touchpad has different settings for taps at the corners, and if you tap at the bottom right corner it does Right click. But if you tap at the top right corner it does Middle click. This is the default setting.

Another option which might be simpler and avoids startup scripts is the following.

1. Stop the gnome settings daemon from overriding existing settings (font: Touchpad Synaptics - ArchWiki).

   gsettings set org.gnome.settings-daemon.plugins.mouse active false
   

2. Edit the X11 configuration file for the touchpad.

   sudo -H gedit /usr/share/X11/xorg.conf.d/50-synaptics.conf
   

   and add your button options under the section with the synaptics driver, like so:

   Section "InputClass"
       Identifier "touchpad catchall"
       Driver "synaptics"
       MatchIsTouchpad "on"
       MatchDevicePath "/dev/input/event*"
           Option "TapButton1" "1"
           Option "TapButton2" "3"
           Option "TapButton3" "2"
           Option "HorizTwoFingerScroll" "on"
           Option "VertTwoFingerScroll" "on"
   EndSection
   

synclient ClickFinger3=2
synclient TapButton3=2

To show the list of actual values:

synclient -l

hope it helps (it did for me!)

You can enable it with the command synclient TapButton3=2 in the terminal, but that seems to get overridden on suspend+resume and after a reboot.

Permanent solution:

It's explained for Xfce in this Xfce forum thread

However, unity-2d (and I suppose also Unity) likes to fiddle with these settings on resume, and I have no idea how to disable that. maybe it's utouch, I don't really know.

The bottom line is that there is a way to configuring middle click permanently:

• add a custom startup application (under the 'gear' menu in unity on the top right) with any name you like, e.g. "touchpad tweak" and the command sh -c "/usr/bin/synclient TapButton3=2", then save it.

This is well and good until you suspend and resume. for that:

• Open a terminal, and type gksudo gedit /etc/pm/sleep.d/80-synaptics-three-finger

• Copy and paste the following text into the file:

  #!/bin/sh
  
  # Restore three finger tapping
  
  case "$1" in
          resume|thaw)
                  sleep 5;
                  /bin/su YOUR_USER_NAME -c "/usr/bin/synclient TapButton3=2"
                  ;;
  esac
  

• Replace YOUR_USER_NAME with your login name - not the long one; e.g. use 'fred' instead of 'fred fuchs'. if you don't remember it, you can always type whoami in a terminal window and it'll tell you.

• Save the file.

• Make it executable; simply type sudo chmod +x /etc/pm/sleep.d/80-synaptics-three-finger in the terminal window. it will ask for your password.

If you did all this correctly, your system should retain three finger clicking as middle click after a suspend/resume cycle.

Now that was fun and user-friendly, wasn't it? I can only wonder why unity silently meddles with synclient settings and wonder even more why there isn't a simple GUI tool to configure all of this. anyway, there you have it.

Download synaptiks from the Software Center.

Open it, then go to Touchpad Configuration >> Tapping.

Set your configuration there, as you would like.

I tried several solutions offered here, but nothing was working on my Toshiba Satellite. The trick seems to be the distinction between a "touchpad" which is a mouse pad with buttons adjacent to it, and a "clickpad" which is a pad with no adjacent buttons: you click the pad.

This Toshiba Satellite has a clickpad, so clicking in the corner didn't work, and I couldn't get three-finger click to work.

Based on dllud's answer, I found I had to edit (on kubuntu) /usr/share/X11/xorg.conf.d/50-synaptics.conf based on information at https://wiki.archlinux.org/index.php/Touchpad_Synaptics#Buttonless_touchpads_.28aka_ClickPads.29 and I now have sections like so:

Section "InputClass"
    Identifier "Default clickpad buttons"
    MatchDriver "synaptics"
    Option     "SoftButtonAreas"  "60% 0 82% 0 40% 59% 82% 0"
EndSection

This sets the pad to be 40% left button, 20% middle button, 40% right button. It still takes some practice to hit the middle correctly.

Touchpad with buttons

I used to have a laptop with touchpad buttons, and to click both of them simultaneously to cause middle click emulation.

Touchpad without button

I now have a buttonless touchpad. Here is what I did:

Use the following command to learn about your touchpad size values and configuration:

$ synclient -l | grep 'Area\|Edge\|ClickFinger' 
LeftEdge                = 129
RightEdge               = 3105
TopEdge                 = 126
BottomEdge              = 2211
VertEdgeScroll          = 0
HorizEdgeScroll         = 0
ClickFinger1            = 1
ClickFinger2            = 3
ClickFinger3            = 0
AreaLeftEdge            = 0
AreaRightEdge           = 0
AreaTopEdge             = 0
AreaBottomEdge          = 0
RightButtonAreaLeft     = 1617
RightButtonAreaRight    = 0
RightButtonAreaTop      = 1916
RightButtonAreaBottom   = 0
MiddleButtonAreaLeft    = 0
MiddleButtonAreaRight   = 0
MiddleButtonAreaTop     = 0
MiddleButtonAreaBottom  = 0

Then use synclient var1=value1 var2=value2 ... syntax to modify those values to suit your needs. See the example command I give belo

Note that:

• ClickFinger1, ClickFinger2 and ClickFinger3 options remap clicks when they are done with respectively one, two or three fingers left touching the touchpad.
• Value 1 corresponds to left click.
• Value 2 corresponds to middle click.
• Value 3 corresponds to right click.

Here is the command I ran and set in the Startup Applications Preferences window to configure my touchpad:

$ synclient RightButtonAreaTop=0 RightButtonAreaLeft=0   MiddleButtonAreaTop=1916 MiddleButtonAreaLeft=1617  ClickFinger1=0

• RightButtonAreaTop=0 and RightButtonAreaLeft=0 unset the "right button" causing right click (I failed to use ivan-volosyuk's settings to have all three buttons set. I only have middle click). I use two-finger tap to produce right click. Not being able to maintain right click is not bothering enough to push me to find a solution.

• MiddleButtonAreaTop=1916 and MiddleButtonAreaLeft=1617 set the "right button" to cause middle click.

• ClickFinger1=0 Disables the special interpretation of the click which happen when one finger touches the surface at the moment of the click. Its previous value: ClickFinger1=1 caused my right clicks being interpreted as left click when leaving a non-clicking finger touching the touchpad.

Hack it the way you like. Maybe you'll do better than me.

Check this. http://forums.debian.net/viewtopic.php?p=354960#p354960 I have put on startup

Touchpad has different settings for taps at the corners, and if you tap at the bottom right corner it does Right click. But if you tap at the top right corner it does Middle click. This is the default setting.

simple bro works for me :)
