9.4. What Are dconf Profiles?
A profile is a list of system's hardware and software configuration databases, which the
dconfprofiles allow you to compare identical systems to troubleshoot hardware or software problems.
dconfsystem stores its profiles in text files. The
$DCONF_PROFILEenvironment variable can specify a relative path to the file from the
/etc/dconf/profile/directory, or an absolute path, such as in a user's home directory.
Key pairs which are set in a
dconfprofile will override the default settings unless there is a problem with the value that you have set.
9.4.1. Selecting a dconf Profile
$DCONF_PROFILEenvironment variable whether the variable is set. If set,
dconfattempts to open the named profile and aborts if this step fails.
As long as the environment variable is not set,
dconfattempts to open the profile named user. Provided this step still fails,
dconffalls back to an internal hard-wired configuration.
Each line in a profile specifies one
dconfdatabase. The first line indicates the database used to write changes whereas the remaining lines show read-only databases. The following is a sample profile stored in
user-db:user system-db:local system-db:site
This sample profile specifies three databases: user is the name of the user database which can normally be found in
~/.config/dconf, and local and site are system databases, located in
dconfprofile for a session is determined at login, so users will have to log out and log in to apply a new
dconfuser profile to their session.
