# Systemwide Custom Gnome Settings with dconf

Gnome configuration is backed by [`dconf`](https://wiki.gnome.org/Projects(2f)dconf(2f)SystemAdministrators.html).

## Some Tooling


### Dump all dconf Configuration
```
$ dconf dump /
[org/gnome/control-center]
last-panel='applications'

[org/gnome/desktop/input-sources]
sources=[('xkb', 'us'), ('xkb', 'de'), ('xkb', 'ch')]

[org/gnome/desktop/interface]
toolkit-accessibility=false

[org/gnome/desktop/peripherals/keyboard]
numlock-state=true
...
$
```
You may diff the dump before and after making changes in the GUI settings to see how they are persisted.

### Delete the User Specific Settings

```
rm ~/.config/dconf/user
```


### Check the Value for a Specific Setting

```
# gsettings get org.gnome.nautilus.preferences default-folder-viewer
'list-view'
#
```

## Configuration

### dconf Values

In Hiera `dconf` settings can be configured with the `gnome::dconf::settings` key which contains a hash with the individual paths and therein the individual configurations:
```
gnome::dconf::settings:
  'org/gnome/nautilus/preferences':
    'default-folder-viewer': "'list-view'"
  'org/gnome/settings-daemon/plugins/power':
    'idle-dim': false
    'power-saver-profile-on-low-battery': false
    'sleep-inactive-ac-timeout': 3600
    'sleep-inactive-ac-type': "'nothing'"
    'sleep-inactive-battery-type': "'nothing'"
```

Note that for string values it needs an apostrophe (`'`) around which needs to survive YAML parsing.
Best surround it with an additional set of `"`.
