Comfortable Swipe (Ubuntu)

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.

Installation

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-ubuntu.git
   cd comfortable-swipe-ubuntu
   

3. Install

   bash install
   

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

How to Run

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. Optional: Change configurations (see below). After making changes, run

   comfortable-swipe restart
   

Configurations

Comfortable swipe makes use of keyboard shortcuts for configurations. The configuration file is located at /usr/local/share/comfortable-swipe/comfortable-swipe.conf. Make sure to run comfortable-swipe restart after making changes.

Property	Description	Default Value	Default Behavior
threshold	mouse pixels to activate swipe; higher = less sensitive; floating-point (Note: Sky is the limit! Can be as large as 1000.0)	0.0
left3	3-finger swipe left	ctrl+shift+Right	switch to right workspace
left4	4-finger swipe left	ctrl+alt+shift+Right	move window to right workspace
right3	3-finger swipe right	ctrl+shift+Left	switch to left workspace
right4	4-finger swipe right	ctrl+alt+shift+Left	move window to left workspace
up3	3-finger swipe up	ctrl+shift+Down	switch to bottom workspace
up4	4-finger swipe up	ctrl+alt+shift+Down	move window to bottom workspace
down3	3-finger swipe down	ctrl+shift+Down	switch to above workspace
down4	4-finger swipe down	ctrl+alt+shift+Up	move window to above workpace

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.

Debugging

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.
