### LIBINPUT-GESTURES [Libinput-gestures][REPO] is a utility which reads [libinput gestures](https://wayland.freedesktop.org/libinput/doc/latest/gestures.html) from your touchpad and maps them to gestures you configure in a configuration file. Each gesture can be configured to activate a shell command which is typically an [_xdotool_][XDOTOOL] command to action desktop/window/application keyboard combinations and commands. See the examples in the provided `libinput-gestures.conf` file. My motivation for creating this is to use triple swipe up/down to switch workspaces, and triple swipe right/left to go backwards/forwards in my browser, as per the default configuration. This small and simple utility is only intended to be used temporarily until GNOME and other DE's action libinput gestures natively. It parses the output of the _libinput list-devices_ and _libinput debug-events_ utilities so is a little fragile to any version changes in their output format. This utility is developed and tested on Arch linux using the GNOME 3 DE on Xorg and Wayland. It works somewhat incompletely on Wayland (via XWayland). See the WAYLAND section below and the comments in the default `libinput-gestures.conf` file. It has been [reported to work with KDE](http://www.lorenzobettini.it/2017/02/touchpad-gestures-in-linux-kde-with-libinput-gestures/). I am not sure how well this will work on all distros and DE's etc. The latest version and documentation is available at https://github.com/bulletmark/libinput-gestures. ### INSTALLATION IMPORTANT: You must be a member of the _input_ group to have permission to read the touchpad device: sudo gpasswd -a $USER input After executing the above command, **log out of your session completely**, and then log back in to assign this group (or just reboot). NOTE: Arch users can just install [_libinput-gestures from the AUR_][AUR]. Then skip to the next CONFIGURATION section. You need python 3.4 or later, python2 is not supported. You also need libinput release 1.0 or later. Install prerequisites: # E.g. On Arch: sudo pacman -S xdotool wmctrl # E.g. On Debian based systems, e.g. Ubuntu: sudo apt-get install xdotool wmctrl # E.g. On Fedora: sudo dnf install xdotool wmctrl Debian and Ubuntu users may also need to install `libinput-tools` if that package exists in your release: sudo apt-get install libinput-tools Install this software: git clone https://github.com/bulletmark/libinput-gestures.git cd libinput-gestures sudo make install (or sudo ./libinput-gestures-setup install) ### CONFIGURATION It is helpful to start by reading the documentation about [what libinput calls gestures](https://wayland.freedesktop.org/libinput/doc/latest/gestures.html). Many users will be happy with the default configuration in which case you can just type the following and you are ready to go: libinput-gestures-setup autostart libinput-gestures-setup start Otherwise, if you want to create your own custom gestures etc, keep reading .. 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. The available gestures are: - swipe up (e.g. map to GNOME/KDE/etc move to next workspace) - swipe down (e.g map to GNOME/KDE/etc move to prev workspace) - swipe left (e.g. map to Web browser go forward) - swipe right (e.g. map to Web browser go back) - pinch in (e.g. map to GNOME open/close overview) - pinch out (e.g. map to GNOME open/close overview) NOTE: If you don't use "natural" scrolling direction for your touchpad then you may want to swap the default left/right and up/down configurations. You can choose to specify a specific finger count, typically [3 or more fingers for swipe](https://wayland.freedesktop.org/libinput/doc/latest/gestures.html#swipe-gestures), and [2 or more for pinch](https://wayland.freedesktop.org/libinput/doc/latest/gestures.html#pinch-gestures). If a finger count is specified then the command is executed when exactly that number of fingers is used in the gesture. If not specified then the command is executed when that gesture is invoked with any number of fingers. Gestures specified with finger count have priority over the same gesture specified without any finger count. Of course, 2 finger swipes and taps are already interpreted by your DE and apps [for scrolling](https://wayland.freedesktop.org/libinput/doc/latest/scrolling.html#two-finger-scrolling) etc. IMPORTANT: Test the program. Check for reported errors in your custom gestures, missing packages, etc: # Ensure the program is stopped libinput-gestures-setup stop # Test to print out commands that would be executed: libinput-gestures -d ( to stop) Confirm that the correct commands are reported for your 3 finger swipe up/down/left/right gestures, and your 2 or 3 finger pinch in/out gestures. Some touchpads can also support 4 finger gestures. If you have problems then follow the TROUBLESHOOTING steps below. Apart from simple environment variable and `~` substitutions within the configured command name, `libinput-gestures` does not run the configured command under a shell so shell argument substitutions and expansions etc will not be parsed. This is for efficiency and because most don't need it. However, if you do need this, just add your commands in an executable personal script, e.g. `~/bin/libinput-gestures.sh`. Run that by hand until you get it working then configure that script path as your command in your `libinput-gestures.conf`. In most cases, `libinput-gestures` automatically determines your touchpad device. However, you can specify it in your configuration file if needed. If you have multiple touchpads you can also specify `libinput-gestures` to use all devices. See the notes in the default `libinput-gestures.conf` file about the `device` configuration command. ### STARTING AND STOPPING Search for, and then start, the `libinput-gestures` app in your DE or you can start it immediately in the background using the command line utility: libinput-gestures-setup start You can stop the background app with: libinput-gestures-setup stop You can enable the app to start automatically in the background when you log in (on an XDG compliant DE such as GNOME and KDE) with: libinput-gestures-setup autostart You can disable the app from starting automatically with: libinput-gestures-setup autostop You can restart the app or reload the configuration file with: libinput-gestures-setup restart You can check the status of the app with: libinput-gestures-setup status ### UPGRADE # cd to source dir, as above git pull sudo make install (or sudo ./libinput-gestures-setup install) libinput-gestures-setup restart ### REMOVAL libinput-gestures-setup stop libinput-gestures-setup autostop sudo libinput-gestures-setup uninstall ### WAYLAND AND OTHER NOTES This utility exploits `xdotool` which unfortunately only works with X11/Xorg based applications. So `xdotool` shortcuts for the desktop do not work under GNOME on Wayland which is now the default since GNOME 3.22. However, it is found that `wmctrl` desktop selection commands do work under GNOME on Wayland (via XWayland) so this utility adds a built-in `_internal` command which can be used to switch workspaces using the swipe commands. The `_internal` `ws_up` and `ws_down` commands use `wmctrl` to work out the current workspace and select the next one. Since this works on both Wayland and Xorg, and with GNOME, KDE, and other EWMH compliant desktops, it is now the default configuration command for swipe up and down commands in `libinput-gestures.conf`. See the comments in that file about other options you can do with the `_internal` command. Unfortunately `_internal` does not work with Compiz for Ubuntu Unity desktop so also see the explicit example there for Unity. Of course, `xdotool` commands do work via XWayland for Xorg based apps so, for example, page forward/back swipe gestures do work for Firefox and Chrome browsers when running on Wayland as per the default configuration. Note that GNOME on Wayland natively implements the following gestures: - 3 finger pinch opens/close the GNOME overview. - 4 finger swipe up/down changes workspaces. So if you choose to run `libinput-gestures` on Wayland, be sure to change or disable the your `libinput-gestures.conf` pinch and swipe up/down gestures to not clash with these. E.g, configure your `libinput-gestures.conf` pinch gestures for only 2 fingers, and the swipe up/down for only 3 fingers so they work independently of the native gestures. GNOME on Xorg does not natively implement any gestures. ### EXTENDED GESTURES They are not enabled in the default `libinput-gestures.conf` configuration file but you can enable extended gestures which augment the gestures listed above in CONFIGURATION. See the commented out examples in `libinput-gestures.conf`. - swipe right_up (e.g. jump to next open browser tab) - swipe left_up (e.g. jump to previous open browser tab) - swipe left_down (e.g. close current browser tab) - swipe right_down (e.g. reopen and jump to last closed browser tab) - pinch clockwise - pinch anticlockwise So instead of just configuring the usual swipe up/down and left/right each at 90 degrees separation, you can add the above extra 4 swipes to give a total of 8 swipe gestures each at 45 degrees separation. It works better than you may expect, at least after some practice. It means you can completely manage browser tabs from your touchpad. ### TROUBLESHOOTING Please don't raise a github issue but provide little information about your problem, and please don't raise an issue until you have considered all the following steps. **If you raise an issue ALWAYS include the output of `libinput-gestures -l` to show the environment and configuration you are using, regardless of what the issue is about**. 1. Ensure you are running the latest version from the [libinput-gestures github repository][REPO] or from the [Arch AUR][AUR]. 2. Ensure you have followed the installation instructions here carefully. The most common mistake is that you have not added your user to the _input_ group and re-logged in as described above. 3. Perhaps temporarily remove your custom configuration to try with the default configuration. 4. Run `libinput-gestures` on the command line in debug mode while performing some 3 and 4 finger left/right/up/down swipes, and some pinch in/outs. In debug mode, configured commands are not executed, they are merely output to the screen: ```` libinput-gestures-setup stop libinput-gestures -d ( to stop) ```` 5. Run `libinput-gestures` in raw mode by repeating the same commands as above step but use the `-r` (`--raw`) switch instead of `-d` (`--debug`). Raw mode does nothing more than echo the raw gesture events received from `libinput debug-events`. If you see `POINTER_*` events but no `GESTURE_*` events then unfortunately your touchpad and/or libinput combination can report simple finger movements but does not report multi-finger gestures so `libinput-gestures` will not work. Also note that discrimination of `SWIPE` and `PINCH` gestures is done completely within libinput, before they get to `libinput-gestures`. 6. Search the web for Linux kernel and/or libinput issues relating to your specific touchpad device and/or laptop/pc. Update your BIOS if possible. 7. Be sure that a configured external command works exactly how you want when you run it directly on the command line, **before** you configure it for `libinput-gestures`. E.g. run `xdotool` manually and experiment with various arguments to work out exactly what arguments it requires to do what you want, and only then add that command + arguments to your custom configuration in `~/.config/libinput-gestures.conf`. Clearly, if the your manual `xdotool` command does not work correctly then there is no point raising an `libinput-gestures` issue about it! 8. **If you raise an issue, always include the output of `libinput-gestures -l` to show the environment and configuration you are using**. If appropriate, also paste the output from steps 4 and 5 above. If your device is not being recognised by `libinput-gestures` at all, paste the complete output of `libinput list-devices` (`libinput-list-devices` on libinput < v1.8). ### LICENSE Copyright (C) 2015 Mark Blakeney.
