<title>Custom default values for system settings</title>
32
<p>System-wide default values can be set using dconf's <em>key file
33
directories</em>. Key files contain <em>groups</em> and <em>key-value pairs
36
<p>To demonstrate how dconf key files can be used to set default values,
37
we'll look at how to use them to set a default wallpaper.</p>

<comment><p>You don't have to use "local" as the profile name. You can even have
40
different profiles for different users. This isn't mentioned because this
41
functionality needs something like accountsservice integration to enforce this.
42
gnome-control-center integration would be great too.</p></comment>

<p>The first time you create a dconf user profile, you'll need to log out
79
and log in to apply the new profile.</p>
85
You can include multiple sets of groups and key-value pairs in each key file,
86
or you can use a separate key file for each group.
