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?

Edit

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.

Edit

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!

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). :)

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.

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.

I'm not sure how applicable this is going to be for this case, but helped me. My issue was that Remmina was not "showing" any windows of GNOME apps, like settings, nautilus, TexEditor, etc. Looks like those used GPU to render, which seems to have been my problem.

What I did was set Software Rendering for all GNOME Apps. On remote host:

echo "export LIBGL_ALWAYS_SOFTWARE=1" >> ~/.xsessionrc
echo "export LIBGL_ALWAYS_SOFTWARE=1" >> ~/.profile

Then log out and reconnect.

This forces GNOME apps to use software rendering instead of GPU acceleration, which for me resolved XRDP rendering issues.
