Coming mostly from Fedora and Archlinux I used to have the latest libinput available in a reasonable time. Currently, on ubuntu 18.04 I do not see how can I have the latest libinput e.g. 1.12 at the time of writing on my machine. Is there a ppa or has anyone tried to install it from source without messing up the whole system?

I do not mind to compile it but I am not well educated in testing it and making sure it is working in conjunction with other packages properly. Having ThinkPad TrackPoint I kinda feel having the latest libinput is crucial!

  • I was about to write an answer, but figured I don't know how to assemble a package correctly (specifically, which packages your libinput-git would replace, there's more than one), and don't have Ubuntu handy to test (I'm on Archlinux). Hopefully, you can build an answer upon my next comment. – Hi-Angel Sep 12 '18 at 5:16

    More-or-less recent packages probably can be gotten from here. Building from source is easy: git clone https://gitlab.freedesktop.org/libinput/libinput.git, and then follow steps from the build() function from here (correct libexecdir to /usr/lib/x86_something). And lastly, you need to assemble a package from it with checkinstall -D make install command. – Hi-Angel Sep 12 '18 at 5:16

    To address the making sure it is working in conjunction with other packages properly: the meson build (from the linked build() function) will take care of dependencies (and if not, it's a bug). You only need to take care of writing correct dependencies for package manager; checkinstall command will ask you about them (I didn't look at man for checkinstall, but it's likely you can just write a config, and feed it to checkinstall). Main purpose is to not have same file /foo in two different packages, and hence of 2 different versions (tho hopefully apt will throw an error then). – Hi-Angel Sep 12 '18 at 8:56
  • Thank you very much for the info in here. I never had experience with meson, and to be fair compilation has been fairly straightforward. I was just not sure if I should use the binaries since I didn't want to break anything, but since there is no other solution I will try and report in here about the outcome. thanks. – Mohamad Sep 13 '18 at 11:09

    I will leave it here. To let users find instructions on how to build libinput. wayland.freedesktop.org/libinput/doc/latest/building.html – Vadym K Jul 25 '19 at 14:20

Here was another answer, but it's been a month since author deleted it. Let's write a new one.

Hopefully, someday someone will create a PPA with latest libinput. Until then, here are instructions on building a latest libinput package yourself.

It is easy, instructions below are mainly taken from here, and the tip about meson is taken from deleted answer. I also assume you don't need to generate docs, so I don't install dependencies for them and disable them in meson call. It's also important for --prefix to be usr in meson-configuration line, so libraries are installed to standard locations.

Step1: install build depenendencies

Hopefully I didn't miss any, but feel free to comment if I did.

$ sudo apt install -y git ninja-build
$ sudo apt build-dep libinput

You'll also need meson. It is in Ubuntu repo, however in the next command I install it with pip. The reason is: due to Ubuntu mostly providing ancient software there's a possibility their meson version will be too old to be able to build libinput. ATM Ubuntu 18.04 is known to have this problem, but I assume with time it may happen to other releases as well.

$ sudo apt install python3-pip
$ sudo pip3 install meson

Step2: clone and build libinput

$ git clone https://gitlab.freedesktop.org/libinput/libinput
$ cd libinput
$ meson --prefix=/usr -Ddocumentation=false build/
$ ninja -C build/

Step3: create libinput package and install

Though easiest way of installing built libinput is running ninja -C build install, but I strongly discourage that unless you know what you're doing (you will get untracked files all over your system that may get overwritten on system update, and depending on situation may even break libinput completely).

Instead, use this script I've written to assemble a package.

$ wget https://gist.githubusercontent.com/Hi-Angel/45030ab89a2378b42511612cbe48d247/raw/package-deb-libinput.sh
$ bash ./package-deb-libinput.sh  build/
dpkg-deb: building package 'libinput-git' in 'libinput_1.15.3-212-g60edbd2d.deb'.

You can see the name of the new package in the script output, so all that is left is to install it (note: the ./ part in the path is needed for apt to correctly interpret argument as a local file):

$ sudo apt install -y ./build/libinput_1.15.3-212-g60edbd2d.deb

To make use of installed libinput you need to restart graphics session (for example, reboot).

Reverting to older libinput

May you wish to get back the distro-provided libinput, just install libinput10 package (it will replace libinput-git):

$ apt install -y libinput10


In case something happens to github gist, here's the current content of the script:

set -e

if [ "$#" -ne 1 ]; then
    echo "Wrong number of parameters.
Usage: $(basename $0) build_dir"
    exit 1

MESON_BUILD_ROOT=$(readlink -f $1)
PACKAGE_VERSION=$(grep -Po 'LIBINPUT_GIT_VERSION.*"\K.+(?=")' "$MESON_BUILD_ROOT"/libinput-git-version.h)
