# GNOME Session Manager

The GNOME session manager is in charge of starting the core components of the
GNOME desktop, and applications that should be launched at login time. This
module is also a natural place for various configuration files that define
important settings that are applied to the GNOME desktop, such as selecting
which xdg-desktop-portal backends to use.

## Building and Installing

Before you can build `gnome-session`, you need the following dependencies:

- A C compiler
- Meson
- Ninja
- `json-glib`
- `systemd`
- `gtk3`
- `gnome-desktop3`

If you're building with X11 support, you'll also need:

- `libSM`
- `libICE`
- `xtrans`
- `libglvnd`

Once you have all the necessary dependencies, you can use Meson to build
`gnome-session`:

```

And finally, you can use Meson to install `gnome-session` to your system:

```
$ sudo meson install -C_build
