New, and updated, installation of Ubuntu 22.04 on a Asus K52J Pc (2010). The gnome-control-center (aka Gnome system Settings) is not opening.

I can see the icon on the left bar, and if I right-click on it, under All Windows, I can also see the preview of the opened window, but it doesn't show.

Trying to do sudo gnome-control-center gives

(gnome-control-center:19545): dconf-WARNING **: 15:18:02.653: failed to commit changes to dconf: Failed to execute child process “dbus-launch” (No such file or directory)
Error creating rfkill proxy: (null)
Segmentation fault

Any solution?


I tried to

sudo apt purge gnome-control-center
sudo apt install gnome-control-center

with no result. Also tried to

sudo apt install dbus-x11

with no result.


Found out that also Libre Office is not opening... maybe that's related.

I had the same issue and the "purge/install gnome-control-center" approach worked like a charm. Problem solved!

  • purging and reinstalling didn't work for me. It was reinstalled again with Display Mode set as 2 Join Displays.

I had the same issue - after upgrading to 22.04, my gnome-control-center was not there.

If I tried 'apt install gnome-control-center', it appeared, I had a broken package, apparently installed without apt, and had to do (in my case, it was remmina and libfreerdp, 'apt remove remmina libfreerdp-2.2', then 'apt autoremove', to clean up.

I could get remmina back with 'apt install remmina', which fetched an apt supported application.

Now, I was able to do 'apt install gnome-control-center', and got the settings back (phew, luckily, the gnome settings is a nice thing to have available). :)


issue: On Ubuntu 22.04, Settings was not showing up

problem: Ubuntu came set w/ Display Mode set w/ 2 Join Displays (even though just 1 laptop built-in display has always been physically available). Settings was opening on the other display (and clicking on preview on left pane is apparently no meant to switching display).

solution: Shift+Super+Left or Shift+Super+Right move window one monitor to left or right making Settings showing up. Also Super+Tab (switching application) or Super+Up (maximizing window) and SUper+Down (minimizing window) can help. After managing to show the Settings, go to Display and in Display Mode set Single Display.


An alternative solution that may be applicable to some using wine32 is switching from libgd3:i386 to 64 bit version.

I specifically ran:

sudo apt install gnome-control-center colord libgd3

To fix it in my situation.

  • Works fro me, too. Thanks!
