Synopsis

This module allows modifications and reading of dconf database. The module is implemented as a wrapper around dconf tool. Please see the dconf(1) man page for more details.
Since dconf requires a running D-Bus session to change values, the module will try to detect an existing session and reuse it, or run the tool via dbus-run-session.

Parameters

Parameter	Choices/Defaults	Comments
key string / required		A dconf key to modify or read from the dconf database.
state string	Choices: read present ← absent	The action to take upon the key/value.
value string		Value to set for the specified dconf key. Value should be specified in GVariant format. Due to complexity of this format, it is best to have a look at existing values in the dconf database. Required for state=present.

Notes

Note

This module depends on psutil Python library (version 4.0.0 and upwards), dconf, dbus-send, and dbus-run-session binaries. Depending on distribution you are using, you may need to install additional packages to have these available.
Detection of existing, running D-Bus session, required to change settings via dconf, is not 100% reliable due to implementation details of D-Bus daemon itself. This might lead to running applications not picking-up changes on the fly if options are changed via Ansible and dbus-run-session.
Keep in mind that the dconf CLI tool, which this module wraps around, utilises an unusual syntax for the values (GVariant). For example, if you wanted to provide a string value, the correct syntax would be value="'myvalue'" - with single quotes as part of the Ansible parameter value.
When using loops in combination with a value like "[('xkb', 'us'), ('xkb', 'se')]", you need to be aware of possible type conversions. Applying a filter "{{ item.value | string }}" to the parameter variable can avoid potential conversion problems.
The easiest way to figure out exact syntax/value you need to provide for a key is by making the configuration change in application affected by the key, and then having a look at value set via commands dconf dump /path/to/dir/ or dconf read /path/to/key.
