Change dconf keys without logging into X in Puppet

rated 0 times [ 2] [ 0] / answers: 1 / hits: 3909 / 2 Years ago, tue, march 1, 2022, 1:34:34

Is there a way to set a dconf key by command line, without logging into X?

I'd like to use this from Puppet.

If I try (from SSH, as the normal user) a simple

dconf write /desktop/gnome/remote-access/enabled true

I get

error: Command line `dbus-launch --autolaunch=e4d2b270bd8471627460e57c000007f1 --binary-syntax --close-stderr' exited with non-zero exit status 1:

Autolaunch error: X11 initialization failed.

While if I try

DISPLAY=:0 dconf write /desktop/gnome/remote-access/enabled true

I get

error: Command line `dbus-launch --autolaunch=e4d2b270bd8471627460e57c000007f1 --binary-syntax --close-stderr' exited with non-zero exit status 1:

Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyAutolaunch error: X11 initialization failed.

If I remove $HOME/.Xauthority

error: Command line `dbus-launch --autolaunch=e4d2b270bd8471627460e57c000007f1 --binary-syntax --close-stderr' exited with non-zero exit status 1:

I'm testing on Xubuntu 12.04

I managed to solve the problem:

define dconf::key($value) {

    exec { "Setting dconf $title":

        path => "/bin:/usr/bin",

        command => "/bin/sh -c 'eval `dbus-launch --auto-syntax` && dconf write $title $value'",

        user => "user_name",

        group => "user_name",

        unless => "dconf read $title | grep $value",

        require => Package["dconf-tools"]

    }

}
