Comfortable Swipe (Ubuntu)

New in Version 1.1.0! Added mouse move gestures (eg. hold3 = button1)

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.git --depth 1
   cd comfortable-swipe
   

3. Install

   bash install
   

4. You may delete the downloaded comfortable-swipe 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. Check the status of your application by running

   comfortable-swipe status
   

Swipe Configurations

Comfortable swipe makes use of keyboard shortcuts for configurations.

1. Edit by running

   gedit $(comfortable-swipe config)
   

2. List of possible configurations:

   Property	Description	Default Value	Default Behavior
   left3	3-finger swipe left	ctrl+alt+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+alt+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+alt+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+alt+Down	switch to above workspace
   down4	4-finger swipe down	ctrl+alt+shift+Up	move window to above workpace
   threshold	mouse pixels to activate swipe	0.0	tweak this if you're having troubles with touchpad sensitivity (higher = less sensitive, values can be as large as 1000.0)
   hold3	holds a mouse button when 3 fingers are down	(none)	See Mouse Gestures
   hold4	holds a mouse button when 4 fingers are down	(none)	See Mouse Gestures

3. After making changes, make sure to restart the program:

   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.

Mouse Gestures

Note

: Setting hold3 or hold4 will ignore its corresponding up/right/down/left command.

We have included simple mouse gestures on swipe by setting hold3 and hold4.

Possible values:

• move - just move the mouse
• button1 - left click
• button2 - middle click
• button3 - right click
• button4 - wheel up (experimental)
• button5 - wheel down (experimental)
• scroll - natural scrolling (experimental)
• scroll_reverse - reverse scrolling (experimental)

Example Configuration

Edit with gedit $(comfortable-swipe config):

# File: comfortable-swipe.conf

# four-finger drag
hold4 = button1

# show desktop
down3 = super+d

# show workspaces
up3 = super+s

# switch workspace
left3 = ctrl+alt+Right
right3 = ctrl+alt+Left

# disabled because of hold4
left4 = ctrl+alt+shift+Right
right4 = ctrl+alt+shift+Left

# three-finger middle click (experimental)
# hold3 = button2

# three-finger scroll (experimental)
# hold3 = scroll
# hold3 = scroll_reverse

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.
