Comfortable, seamless, and fast 3-finger (and 4-finger) touchpad swipe gestures for Ubuntu 14.04 LTS and beyond. May work for other Linux distros that support libinput.

1. Install git, libinput, and g++

   sudo apt-get install git libinput-tools libxdo-dev g++

2. Clone this repository

   git clone https://github.com/Hikari9/comfortable-swipe.git --depth 1
   cd comfortable-swipe

3. Install

   bash install

4. You may delete the downloaded comfortable-swipe folder after installation.

1. You'll need some group permissions to read touchpad input data. Run

   sudo gpasswd -a $USER $(ls -l /dev/input/event* | awk '{print $4}' | head --line=1)

2. Important: After inputing your sudo password, log out then log back in
3. Run

   comfortable-swipe start
   

4. Optional: Automatically run on startup

   comfortable-swipe autostart
   

5. Check the status of your application by running

   comfortable-swipe status
   

Comfortable swipe makes use of keyboard shortcuts for configurations. Edit by running

gedit $(comfortable-swipe config)

Make sure to run after making changes:

comfortable-swipe restart

Taken from man xdotool:

Type a given keystroke. Examples being "alt+r", "Control_L+J", "ctrl+alt+n", "BackSpace".

Generally, any valid X Keysym string will work. Multiple keys are separated by '+'. Aliases exist for "alt", "ctrl", "shift", "super", and "meta" which all map to Foo_L, such as Alt_L and Control_L, etc.

In cases where your keyboard doesn't actually have the key you want to type, xdotool will automatically find an unused keycode and use that to type the key.

Refer to https://www.linux.org/threads/xdotool-keyboard.10528/ for a complete list of keycodes you can use.

You can check your touchpad driver by running

comfortable-swipe debug

This is an alias of libinput debug-events. This logs all gestures you make on your touchpad, along with other input-based events that can be captured by libinput.

A working swipe gesture will show the following:

$ comfortable-swipe debug

If you can see GESTURE_SWIPE_XXX in your output, that means your touchpad supports multi-touch swipe gestures.
