Settings Do Not Work


I have installed EOS with Budgie Desktop and Gnome Control Center stopped working not long after I launched the OS. I am sure it did work for some time. It possibly stopped working after I updated the system.

Here’s an error I get when I launch gnome-control-center:

$ gnome-control-center 

(gnome-control-center:20767): cc-wwan-panel-WARNING **: 16:36:00.785: Error connecting to ModemManager: Error calling StartServiceByName for org.freedesktop.ModemManager1: Unit dbus-org.freedesktop.ModemManager1.service not found.

(gnome-control-center:20767): GLib-GIO-ERROR **: 16:36:00.822: Settings schema '' is not installed

On Manjaro forum it is reported, “I remembered that it crashed when I viewed “multitasking” panel.”

Exactly. I remember that I clicked on “Multitasking” - the Settings crashed and stopped working. Reboots do not help.

Not sure if reinstalling could fix some dependency

Thanks for the answers.

Tried reinstalling using pacman but it didn’t help.

I am using Plata-Compact that was installed using Pacman. It is a native Solus Budgie theme.

I have seen this workaround, yes, but there seemingly is no gsettings in the repositories, neither in AUR, nor in official bases.

I pasted the quote below, for convenience.

Okay I found a temporary workaround. I remembered that it crashed when I viewed “multitasking” panel. So I used gsettings to check the keys of org.gnome.ControlCenter

gsettings list-keys org.gnome.ControlCenter 

then check

gsettings get org.gnome.ControlCenter last-panel 

this is the problematic panel that was crashing the control center every time. So I did

gsettings reset org.gnome.ControlCenter last-panel

and voila, I can open settings again. Not touching that panel till this gets fixed!

yes I can reproduce this…

[joe@joe-virtualbox ~]$ LANG=C pacman -Qo /usr/share/applications/gnome-multitasking-panel.desktop
/usr/share/applications/gnome-multitasking-panel.desktop is owned by gnome-control-center 41.2-3

so it is part of G-C-C itself… but they are related to gnome-shell ?

yes if i install gnome-shell it does start just fine also if i use the multitasking tab just before closing and restart…


no idea if this is still plaguing people like it has me today, but using the info here I have found that the parameter has changed from org.gnome.ControlCenter to org.gnome.Settings.

Therefor if you follow the instructions with this new info it is now:

[setayo@SamsungNP900X3C ~]$ gsettings list-keys org.gnome.Settings
[setayo@SamsungNP900X3C ~]$ gsettings get org.gnome.Settings last-panel
[setayo@SamsungNP900X3C ~]$ gsettings reset org.gnome.Settings last-panel

This then allows the settings to be opened but be careful not to click multitasking again until this is patched for good

I have no issue on Budgie with plata-compact.

Edit: Using Budgie Control Center

Edit2: Budgie Desktop is nice!


remove Gnome control center it is not recommended to be used by Budgie development anymore as they now have their own one.

Everyone should switch to Budgie Control Center. The bug is posted elsewhere on this forum about gnome control center and multitasking setting causing a SEGFAULT.

Is there anyway that we could get a sticky message & a wiki faq or something to make this permanent?
