Configuration of Gnome desktop was changed in Gnome 3.x. It doesn’t use GConf anymore (was used in Gnome 2.x), but it uses DConf as back end and GSettings as high-level configuration system. When you want to set something system-wide, then it can looks like a little bit tricky, but I will show you that is quite simple.
First of all we will need to find, where is desired configuration stored. Gnome 3 does not use any text files for configuration. Gnome 3 uses magic (aka dconf), but don’t be scared it is quite simple and easy to solve almost any problem.
For browsing dconf is best to use Dconf Editor. it can be installed with following command:
# yum install dconf-editor
Then you can simply start this GUI application using:
As you can see, configuration of any Gnome 3 application has some unique path. Each path has at least one key, and key have some type. A type of key could be boolean, string, integer, array of strings.
It is easy to browse and set some settings with
dconf-editor, but when you set something with
dconf-editor, then this setting is user specific and other users will have default values. We can simply prove it with command-line tool
For example, we will want to show date in calendar. This setting has following path:
and one value:
show-weekdate. We can check current value with this command:
$ gsettings get org.gnome.shell.calendar show-weekdate
When we set this value for current user, then there will be value
true, but other users will have still
false in this value.
Go to the directory
/etc/dconf/db/local.d/ and create there new file called (e.g.)
01-calendar and place following content to this file:
Then run following command as root:
# dconf update
All users should see date in calendar (after restarting gnome shell).
