This post is based on my Dell M3800 with linux Neon.

KDE already does a good job with touchpad gestures (e.g., two fingers for scrolling, 3 finger tap for pasting, etc.) but it does not support 3 finger swype gestures like in MacOs, e.g., for displaying all the windows or for showing the desktop.

Today I tried this utility, Libinput-gestures , which works like magic! The utility comes with good default for typical gestures (including pinch) but I configured that to fit my needs (in particular, I wanted to mimic MacOs behavior for 3 finger swypes: up = display all windows, down = display all windows of the same class and for pinch out = show desktop.

The installation of Linput-gestures is really easy (just follow the instructions at its web page).

Remember that, first of all, your user must be in the input group, so first run

sudogpasswd -a $USERinput

Then logout from your current session, and login again.

Then, in Ubuntu, it’s just a matter of running

sudoapt-getinstallxdotoolwmctrllibinput-tools

and install thesoftware like this (you need git):

gitclone http://github.com/bulletmark/libinput-gestures cdlibinput-gestures sudo ./libinput-gestures-setupinstall

You can already start the program like this

libinput-gestures-setupstart

and if you want it to be started at login time, then run

libinput-gestures-setupautostart

The default gestures are in /etc/libinput-gestures.conf . If you want to create your own custom gestures then copy that file to ~/.config/libinput-gestures.conf and edit it.

These are the lines I changed in my configuration (remember that each time you modify the configuration you need to restart libinput-gestures, i.e., instead of start in the command line above, just use restart ):

# KDE: Present Windows (current desktop) gestureswipeupxdotoolkeyctrl+F9 # KDE: Present Windows (Window class) gestureswipedownxdotoolkeyctrl+F7 # KDE: Show desktop gesturepinchoutxdotoolkeyctrl+F12

You only need to know the keyboard shortcuts of the actions you want to associate to mouse gestures. With that respect, you might want to have a look at the current shortcutsin KDE Settings (the interesting components are “KWin” and “Plasma”):
