Multitouch gestures with libinput driver on Linux
MIT License
Fusuma is multitouch gesture recognizer. This gem makes your linux able to recognize swipes or pinchs and assign commands to them.
襖(Fusuma) means sliding door used to partition off rooms in a Japanese house.
IMPORTANT: You MUST be a member of the INPUT group to read touchpad by Fusuma.
sudo gpasswd -a $USER input
Then, You apply the change with no logout or reboot.
newgrp input
IMPORTANT: This makes /dev/input/
readable, so if that's an issue for you for some reason (like for privacy- or securityconcerns etc. or if it causes other parts of your OS to misbehave), consider this your heads-up.
You need libinput
release 1.0 or later.
sudo apt-get install libinput-tools
Fusuma runs in Ruby, so you must install it first.
sudo apt-get install ruby
sudo gem install fusuma
For sending shortcuts:
sudo apt-get install xdotool
You need libinput
release 1.0 or later. This is most probably installed by default on Manjaro
sudo pacman -Syu libinput
Fusuma runs in Ruby, so you must install it first.
sudo pacman -Syu ruby
Note: By default in Arch Linux, when running gem
, gems are installed per-user (into ~/.gem/ruby/
), instead of system-wide (into /usr/lib/ruby/gems/
). This is considered the best way to manage gems on Arch, because otherwise they might interfere with gems installed by Pacman. (From Arch Wiki)
To install gems system-wide, see any of the methods listed on Arch Wiki
sudo gem install fusuma
For sending shortcuts:
sudo pacman -Syu xdotool
For the truly lazy people: As with pretty much anything else available as Open-Source-Software, you can install Fusuma via a package from the AUR. As off time of writing (March 2023), the package you would want is called ruby-fusuma
.
Please keep in mind that this community-built package is NOT officially supported here and while it might do the job, it is not the intended way to install.
Installing Fusuma this way means that if things do not work as intended during or after the installation, you are on your own.
So please do not bombard the Issues-Page here on Github if Fusuma isn't working correctly after installing it via the AUR.
Fusuma's plugins as listed below here in this Readme can be installed as optional dependencies also via the AUR, namescheme being ruby-fusuma-replacewithnameofplugin
.
You need libinput
release 1.0 or later.
sudo dnf install libinput
Fusuma runs in Ruby, so you must install it first.
sudo dnf install ruby
sudo gem install fusuma
For sending shortcuts:
sudo dnf install xdotool
Ensure the touchpad events are being sent to the GNOME desktop by running the following command:
gsettings set org.gnome.desktop.peripherals.touchpad send-events enabled
fusuma
sudo gem update fusuma
You can customize the settings for gestures to put and edit ~/.config/fusuma/config.yml
.
NOTE: You will need to create the ~/.config/fusuma
directory if it doesn't exist yet.
mkdir -p ~/.config/fusuma # create config directory
nano ~/.config/fusuma/config.yml # edit config file.

The following wiki pages can be edited by everyone.
If you have a nice configuration, please share ~/.config/fusuma/config.yml
with everyone.
if command:
properties are blank, the swipe/pinch/hold doesn't execute command.
threshold:
is sensitivity to swipe/pinch/hold. Default value is 1.
If the swipe's threshold is 0.5
, shorten swipe-length by half.
interval:
is delay between swipes/pinches/hold. Default value is 1.
If the swipe's interval is 0.5
, shorten swipe-interval by half to recognize a next swipe.

The individual threshold:

settings (under "direction") have a higher priority than the global one (under "root")
