In almost all the large modern Linux distributions and in the last releases of Ubuntu-based distributions the touchpad was configured out of the box to have right, left and middle clicks and you could configure them easily. The middle click is usually done with a two or three-finger tap.

In Ubuntu 12.04 I haven't seen where to enable the middle click and it is not enabled by default.

Answer will depend somewhat on the type of trackpad you have, but generally it's just a matter of adding the appropriate option to /etc/X11/xorg.conf. Some instructions for Synaptics trackpads: – Chan-Ho Suh May 6 '12 at 10:32

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 > ~/

(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 ~/

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/"

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.

Yeah, I found accidentally one tap on the top right corner on my multitouch touchpad acts like a middle click. Right click is two-finger tap for me. – AliNa May 25 '13 at 11:08
This appears to still be the default in Ubuntu 14.04. I can't believe that htere doesn't seem to be any documentation or even a GUI representation of this in the Mouse & Touchpad settings dialog. – Ryan Fisher Oct 1 '14 at 8:11
Is there any way to disable this? – hellocatfood Apr 1 '15 at 15:42
It's 2015 and this still works :) – Tom Stephens Apr 24 '15 at 1:06
I have to try repeatedly to hit the corner in a way that synaptics recognizes. And then I end up pasting stuff twice. Is there a way to make the "top right corner" bigger? – Jean Jordaan Jul 13 '15 at 16:40

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 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"

As of 13.10, /usr/share/X11/xorg.conf.d/50-synaptics.conf warns "DO NOT EDIT THIS FILE, your distribution will likely overwrite it when updating. Copy (and rename) this file into /etc/X11/xorg.conf.d first." – Firefeather Oct 24 '13 at 15:57
Can you help me how to Simulate a middle-click on Lenovo Yoga 2 Pro Synaptics touchpad too? – rubo77 Jun 20 '14 at 10:11
@Firefeather: Maybe you want your distribution to update it, because it could be, that your distribution finds an even better solution than this. I would just keep in mind to add this again in case the distribution overwrites it – rubo77 Aug 30 '14 at 23:05
@rubo77 the point is that if your distro provides a better solution, then you copy the relevant improvements into the user version in /etc! rather than risk getting your customisations in /usr/share - a directory that should almost always be treated as though it were read-only - trashed, if you don't "keep in mind" all the things you risk losing by not using etc ;-) – underscore_d Feb 29 at 20:33

Download synaptiks from the software center.

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

Set your configuration there, as you would like.

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. I'm also looking for a permanent solution.


okay, so there's a post where it's explained for xfce located here:

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:

    # Restore three finger tapping
    case "$1" in
                    sleep 5;
                    /bin/su YOUR_USER_NAME -c "/usr/bin/synclient TapButton3=2"
  • 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.

The suspend/resume task is something i've been needing to do for a while. Thanks! – tucuxi Sep 14 '12 at 11:10
@kzh: maybe because of my sarcastic tone. or could be because it's better to put it in the xorg.conf (at the end if there's already one) like so: Section "Inputclass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" Option "TapButton3" "2" EndSection – bamdad Sep 16 '12 at 22:19
sorry, the comment form ate my line breaks. you get the point, hopefully. :) in case not, i'll edit my original answer. – bamdad Sep 16 '12 at 22:26
synclient ClickFinger3=2
synclient TapButton3=2

To show the list of actual values:

synclient -l

hope it helps (it did for me!)

share|improve this answer
ClickFinger3=2 is great - now it works like in Debian. – z0r Jun 7 '15 at 6:59
how it works? I set those values, but is not clear how can I tap or click the middle button – juanpastas Jul 18 '15 at 17:18
An exhaustive description of all the settings can be found in the synaptics man page. In this case, the above settings enable middle-clicking by tapping or clicking with three fingers. – Jim Hurne Nov 13 '15 at 11:31

Check this. I have put on startup

xinput set-int-prop 'SynPS/2 Synaptics TouchPad' "Synaptics Tap Action" 8 0 0 0 0 1 3 2

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 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"

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.

Clicking both left and right buttons at the same time works for some systems. See: and search for the term "middle".

If you look in the XFCE wiki for mouse/trackpad settings it will mention how "Device Properties" can be set. Unfortunately it's not complete because direct device settings have to be under Properties/ to take effect. For example, to make two finger touches middle click and three finger touches right click I need to alter "Synaptics Tap Action". Here's what it looks like initially:

$ xinput list-props "ETPS/2 Elantech Touchpad" | grep "Tap Action"
    Synaptics Tap Action (298): 2, 3, 0, 0, 1, 3, 0

To have XFCE 4.12 set this it is necessary to do the following:

xfconf-query -c pointers -p /ETPS2_Elantech_Touchpad/Properties/Synaptics_Tap_Action -n -t int -t int -t int -t int -t int -t int -t int -s 2 -s 3 -s 0 -s 0 -s 1 -s 2 -s 3

Now we can see it changed:

$ xinput list-props "ETPS/2 Elantech Touchpad" | grep "Tap Action"
    Synaptics Tap Action (298): 2, 3, 0, 0, 1, 2, 3

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 :)

How would one configure this? How do you it's the default setting on his computer? – Kaz Wolfe Oct 5 '14 at 21:27

I would recomand adding synclient TapButton2=2 and synclient TapButton3=3 to ~/.barchrc config file

  • synclient TapButton2=2 will set the two finger tap to a middle button click
  • synclient TapButton3=3 will set the 3 finger tap to a right button click

    1. echo synclient TapButton2=2 >> ~/.bachrc
    2. echo synclient TapButton3=3 >> ~/.bachrc
    3. reboot your computer
share|improve this answer
Instead of putting it in your bashrc, you can do the follow. Edit /usr/share/X11/xorg.conf.d/50-synaptics.conf. In the section for your device, add 'Option "TapButton3" "3"'. – Atif Jun 14 at 3:54
