Disable touchpad hardware buttons

I'd like to disable hardware buttons on the synaptic touchpad, but still be able to use the touchpad and "tap"-click on its surface. I don't find the related options in the output of synclient -l.

Note that I don't want to disable the touchpad completely. Only to make it ignore the hardware buttons, but still respond to taps.

Filed a bug against gpointing-device-settings #793440. It seems impossible to do what I want with the current version of the software. Question closed.

This will disable the hardware buttons and the "tap" feature, but you will be able to move the pointer:

1) Create this file:

gedit ~/.Xmodmap  

2) Paste this into it:

pointer = 0 0 0  

3) Logout and log back in, or reboot, or run this:

xmodmap ~/.Xmodmap  

To get it back to normal:

1) Edit the file:

gedit ~/.Xmodmap  

2) And change to:

pointer = default  

3) Logout and log back in, or reboot, or run this:

xmodmap ~/.Xmodmap  

4) If this file doesn't have anything else, then you can delete it after step "3":

rm ~/.Xmodmap  

Disabling Touchpad:

Press Alt+F2 and type gconf-editor and click Run.

Navigate to desktop>gnome>peripherals>touchpad,in the right panel uncheck the entry touchpad_enabled.

Now your touchpad will be disabled.

To turn off touchpad completely install gpointing-device-settings . After installation you can access it under System > Preferences > Touchpad

UPDATE:

• If you want to use synclient then you have to edit your xorg.conf file.

  sudo -H gedit /etc/X11/xorg.conf`
