Description William Jon McCann 2012-07-02 21:40:29 UTC
The pretty hostname is not editable even for admin accounts.

Also, we don't seem to be monitoring the service for name changes.
Comment 1 Matthias Clasen 2012-07-02 21:45:53 UTC
The hostname is not editable because the default policy has

        <action id="org.freedesktop.hostname1.set-hostname">
                <description>Set host name</description>
                <description xml:lang="pl">Ustawienie nazwy komputera</description>
                <message>Authentication is required to set the local host name.</message>
                <message xml:lang="pl">Wymagane jest uwierzytelnienie, aby ustawić nazwę lokalnego komputera.</message>

And gnome-control-center doesn't make the field editable unless the polkit response is 'yes'. Possible solutions:

- add a way to bring up the polkit auth dialog when the reply from polkit is 'maybe'

- override the default policy by installing a rules file that sets allow_active to 'yes'
Comment 2 William Jon McCann 2012-07-03 12:58:03 UTC
Can we make it a "yes" for admins in active sessions?
Comment 3 Matthias Clasen 2012-07-03 19:27:17 UTC
It is possible to write a rule that does that, pretty sure.

has instructive examples
Comment 4 William Jon McCann 2012-07-03 19:28:51 UTC
That would make a reasonable default I think.

<hadess> fredp, another one for 3.6 blockers:
Comment 6 Matthias Clasen 2012-08-22 04:01:30 UTC
Here's a rule that works:

polkit.addRule(function(action, subject) {
        if ( == "org.freedesktop.hostname1.set-static-hostname" &&
            subject.local &&
            subject.isInGroup ("wheel")) {
                return polkit.Result.YES;

Put this in a file called gnome-control-center.rules, and install it in /usr/share/polkit-1/rules.d/
