Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).
Thanks!

This is an issue for me too . settings will not open under either wayland or xorg gnome-session . it does however open when logged in the ubuntu-session.

[Lukas Zaoralek (lukas-zaoralek)]

Same for me. I can open gnome-control-center from terminal, but if I click on the gnome-control-center icon from the menu/launchpad nothing is going to happen. Is there a log to check what is going on?

[Mark Clancey (mark-clancey)]

Same for me after attempting to install GNOME Human Shell Theme Collection, https://www.gnome-look.org/p/1171095/, using the Install button, Human.zip file. It also removed Tweaks from Favorites, which I was able to re-save from Dash. Tweaks does run. But Settings hangs on-launch, then disappears. Anyone know how I can undo the GNOME shell installation?

Well I just reinstalled gnome-control-center
sudo apt install gnome-control-center
and works fine now

Thanks Abhishek AN (darkabhi) . That fixed it for me.

This bug affects me too.
Downloaded 18.04.01 today (5/10/2018)
Fresh install, no changes at installation (next next next ...)
Log in, trying to open settings -> Send Error report
trying to run gnome-control-center from terminal -> Core dump
trying to remove gnome-control-center (is removed with ubuntu-desktop as well)
sudo apt remove gnome-control-center
sudo apt autoremove
sudo apt install gnome-control-center
Still not working. same results as above

I also facing the same problem.
Downloaded 18.04.1 LTS (Jan 6, 2019)
Codename : Bionic

It happen when I tried to change taskbar layout from default (at left side) to bottom. Yes, I tried to put the taskbar at bottom then it crashed. I cannot click "Setting" icon, or click "change background" from desktop display. The icon "setting" (the gear icon) displayed on taskbar but if I click it, the window not display.

I have already remove gnome-control-center, and reinstall it. Still not working, same result as above.

PS : I capture my full window, and strangely enough that "setting" window also automatically captured.

hendra, please don't comment on old closed bugs since people don't really look at closed bugs. It's better to open a new bug isntead.

[hendra (hapesurya)]

Dear Jeremy, noted. I also find another bugs, Cheese. I will open a new bugs report.

[Allan Oepping (allan-ubuntu)]

I recently switched from MATE to Gnome I experience the same problem.
I have found that I can start gnome-control-center if I set the environment variable CLUTTER_BACKEND to wayland. You can start in in your shell like so:

CLUTTER_BACKEND=wayland gnome-control-center

If I check my current environment for clutter environment variables I see:

$set | grep -i clutter
CLUTTER_BACKEND=x11
CLUTTER_IM_MODULE=xim

None of those are set in any of my dot files in my home, the culprit appears to be:

X11/Xsession.d/99mate-environment: export CLUTTER_BACKEND=x11

I have had a working 18.4 system for a few months.
Today a software update ran, which I allowed like I always do.
Then went to play OpenRA and it would not run well enough to play.
So I was going to settings to check the display settings.
Only to be presented with a Select User screen, enter password, then back to Desktop.

I had to search and find how to use terminal and uninstall and reinstall.
I uninstalled gnome-control-center
And re-installed gnome-control-center
Rebooted and still same thing.
I tried opening the gnome-control-center using terminal and same thing.
Select user, enter password, back to desktop.

So far none of the steps I can find will allow me into the settings.

Allan, Chris: It's pointless to add comments on a closed bug report, and this one is closed. Please open new bug reports, if you think you see bugs, or seek support with investigating further (e.g. https://askubuntu.com).
