starting xfce4-display-settings from root run bashscript

10011001 · 2017-01-16 09:44:30

Hi everyone,

I'm trying to start xfce4-display-settings from a root run bash script as a normal user but always get the following error

(xfce4-display-settings:3609): xfce4-display-sttings-ERROR **: Failed to connect to xfconf daemon: Failed to connect to socket /tmp/dbus-VPIPHBhq57: Verbindungsaufbau abgelehnt.

Has anyone experienced the issue or knows how to work around this.

What I do is

su $username xfce4-display-settings

Thanks!

Best Regards

You shouldn't run any of Xfce's configuration components as root. They are not intended to be run as such. The settings are all user or profile-specific, not system or root specific.

Why are you trying to run them as root? What is it that you are trying to do?

I'm writing a provisioning script that automates a few task that are required after the installation of a custom iso for kiosk systems.
The script itself has to be run as root. And I tried to start xfce4-display-settings as the normal user using su but that leads to mentioned error.

Best regards

xfconfd, which manages the Xfce configuration system, is run as a daemon under the logged in users profile. When you try to use one of Xfce's configuration tools, it will connect to that daemon to make the change. If you su to root, it won't work because root doesn't have a current, active, and/or valid xfconfd daemon running.

Therefore, even if you could use this method, none of the changes you would make would affect the current user's profile.

Now, if you are trying to do something else, like change some profile settings for a user profile that is not currently logged in, then just manually change the information in that user's profile's ~/.config/xfce4/xfconf/xfce-perchannel-xml/* config files. Don't use the configuration tools. In your example above, just edit /home/KIOSK_USER/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml using the tool of your choice.
