libinput-config on Fedora Silverblue

libinput-config allows changing input settings that your Wayland compositor may not (e.g. scroll speed on Mutter).

1. Download and build libinput-config:

   $ toolbox enter
   ⬢ $ sudo dnf install -y gcc libinput-devel meson
   ⬢ $ git clone https://gitlab.com/warningnonpotablewater/libinput-config.git
   ⬢ $ cd libinput-config
   ⬢ $ meson build
   ⬢ $ ninja -C build
   ⬢ $ mkdir -p ~/.local/lib64
   ⬢ $ cp build/libinput-config.so ~/.local/lib64
   ⬢ $ exit

2. Add a unit override to load libinput-config (note this step is specific to Gnome):

   $ mkdir -p ~/.config/systemd/user/org.gnome.Shell@wayland.service.d/
   $ cat <<EOF >> ~/.config/systemd/user/org.gnome.Shell@wayland.service.d/libinput-config.conf
   [Service]
   Environment="LD_PRELOAD=%h/.local/lib64/libinput-config.so"
   EOF

3. Edit /etc/libinput.conf and set your desired settings (see How to use).

4. Log out and back in again.

Your settings should now be applied!
