Comfortable Swipe (Ubuntu)

New in Version 1.1.0! Added mouse gestures, see #mouse-gestures-experimental

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. Edit by running:

gedit $(comfortable-swipe config)

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+Up	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 (Experimental)
hold4	holds a mouse button when 4 fingers are down	(none)	See Mouse Gestures (Experimental)

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.

Swipe Gesture Templates

1. Switching workspaces

   # Unity, KDE
   left3 = ctrl+alt+Right
   right3 = ctrl+alt+Left
   up3 = ctrl+alt+Down
   down3 = ctrl+alt+Up
   

   # GNOME
   up3 = super+PgDown
   down3 = super+PgUp
   

2. Move window to workspace

   # Unity, KDE
   left4 = ctrl+alt+shift+Right
   right4 = ctrl+alt+shift+Left
   up4 = ctrl+alt+shift+Down
   down4 = ctrl+alt+shift+Up
   

   # GNOME
   up4 = super+shift+PgDown
   down4 = super+shift+PgUp
   

3. Move window to other monitor

   # GNOME
   left4 = super+shift+Right
   right4 = super+shift+Left
   

4. Toggle workspace overview

   up3 = super+s
   

5. Show desktop (setup manually)

   # Ubuntu
   down3 = ctrl+super+d
   

   # GNOME
   down3 = super+d
   

   # KDE
   down3 = ctrl+alt+d
   

6. Snap windows to the left/right

   left3 = super+Left
   right3 = super+Right
   

7. Toggle maximize

   up3 = super+Up
   

8. Toggle minimize

   down3 = super+Down
   

9. Alt+Tab switch application (experimental)

   left3 = alt+Tab
   right3 = alt+shift+Tab
   

Mouse Gestures (Experimental)

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

Possible Values (hold3, hold4):

move            # just move the mouse cursor (no mousedown)
button1         # hold left click on finger swipe
button2         # hold middle click on finger swipe
button3         # hold right click on finger swipe
button4         # wheel up on finger swipe (experimental)
button5         # wheel down on finger swipe (experimental)
scroll          # naive 3/4 finger natural scroll (no acceleration, very experimental)
scroll_reverse  # naive 3/4 finger reverse scroll (no acceleration, very experimental)

Any value not mentioned above disables the mouse-hold.

Examples:

• 3-finger drag

  hold3 = button1
  

• 4-finger drag (with middle click)

  hold4 = button2
  

• 3-finger natural scroll

  hold3 = scroll
  

• 4-finger reverse scroll

  hold4 = scroll_reverse
  

• Just move the cursor

  hold3 = move
  hold4 = move
  

• Any other command will disable the mouse hold

  hold3 = disabled
  hold4 = nothing
  

Note: Applying any mouse-hold configuration will disable up/left/right/down behavior to avoid gesture conflicts. The logic of this will be improved in the future.

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.
