To enable touch input the same way with two different inputs (and input libs) on modern laptops and netbooks, in UM17.04.

Touchpad gestures (libinput)

[edit] Works well but there is a compiz problem which is annoying. It prevent multiple xdotool calls until a real keyboard input is made. I work on a solution, or a workaround like a d-bus call for compiz

Works well with libinput-gestures

sudo gpasswd -a $USER input
sudo apt-get install xdotool wmctrl libinput-tools
git clone http://github.com/bulletmark/libinput-gestures
cd libinput-gestures
sudo ./libinput-gestures-setup install
libinput-gestures-setup start

Then for example create the following .config/libinput-gestures.conf :

gesture swipe up 3	xdotool key super+w
gesture swipe up 4	xdotool key super+a
gesture swipe down xdotool key ctrl+alt+d
gesture swipe left	xdotool key alt+Right
gesture swipe right	xdotool key alt+Left

If it runs well, you can add the service in startup item

libinput-gestures-setup autostart

then trash the installation directory

Touchscreen gestures (synaptics)

Add the touchegg service

sudo apt install touchegg
mkdir $HOME/touchegg
touch $HOME/touchegg/touchegg.conf
pluma $HOME/touchegg/touchegg.conf

Configuration example with same input gestures than with touchpad:

<touchégg>
  <settings>
    <property name="composed_gestures_time">111</property>
  </settings>
  <application name="All">
  <gesture type="DRAG" fingers="3" direction="UP">
    <action type="SEND_KEYS">Super+w</action>
  </gesture>
  <gesture type="DRAG" fingers="4" direction="UP">
    <action type="SEND_KEYS">Super+a</action>
  </gesture>
  <gesture type="DRAG" fingers="3" direction="DOWN">
    <action type="SEND_KEYS">ctrl+alt+d</action>
  </gesture>
  <gesture type="DRAG" fingers="4" direction="DOWN">
    <action type="SEND_KEYS">ctrl+alt+d</action>
  </gesture>
  <gesture type="DRAG" fingers="3" direction="LEFT">
    <action type="SEND_KEYS">alt+Right</action>
  </gesture>
  <gesture type="DRAG" fingers="3" direction="RIGHT">
    <action type="SEND_KEYS">alt+Left</action>
  </gesture>
  <gesture type="TAP" fingers="2" direction="">
    <action type="MOUSE_CLICK">BUTTON=3</action>
  </gesture>
  </application>
</touchégg>

Then add the touchegg command in the Startup Applications

It’s your turn to customize the gestures to comply to your tastes !
