man 7 dconf:
To facilitate system configuration with a text editor, dconf can
populate databases from plain text keyfiles. For any given system
database, keyfiles can be placed into the /etc/dconf/db/database.d/
directory. The keyfiles contain groups of settings as follows:
# Some useful default settings for our site
After changing keyfiles, the database needs to be updated with the
If you just need to have GNOME pick up settings from a file without scripting, this might be the simplest way, but it needs administrator access for creating the key file.
The other option is to save the binary dconf database itself, but that's not a good option for use with Git as version control. The database is typically located in
~/.config/dconf by default). See section on
PROFILES in the manpage.
The manpage also says:
The binary database format that dconf uses by default is not suitable
for use on NFS, where mmap does not work well. To handle this common
use case, dconf can be configured to place its binary database in
XDG_RUNTIME_DIR (which is guaranteed to be local, but non-persistent)
and synchronize it with a plain text keyfile in the users home
But it's not exactly clear how to do this without scripting.
