After upgrading from Ubuntu 23.04 to Ubuntu 23.10 I can't open settings. I was trying to open settings via terminal using

gnome-control-center

but I got message:

Running gnome-control-center is only supported under GNOME and Unity, exiting

but the problem is I am using GNOME...

I was experimenting with KDE plasma earlier but now I'm clearly using GNOME.

echo $DESKTOP_SESSION

says just "ubuntu"

edit: running

export XDG_CURRENT_DESKTOP='ubuntu:GNOME'

in terminal allowed me to open settings from that terminal

I had the same issue and it came down to the comment from https://askubuntu.com/users/1631199/nteodosio. I could set my environment from the terminal to run gnome-control-center, but this was aggravating.

Looking at how to fix this, I found:

https://ubuntuhandbook.org/index.php/2020/07/change-default-display-manager-ubuntu-20-04/

Running sudo dpkg-reconfigure gdm3 and selecting gdm3 as the login manager, instead of sddm, which is what I had, enabled me to run the control center directly from the icon within the pull-down at the top-right of the Ubuntu control bar.

Note that I needed to reboot, not just logout, so that the new login manager would run.

I suppose I was playing with settings to be able to run alternatives, like Sugar and toggle between XOrg and Wayland, and somewhere got sddm selected as my login manager.

Hope this helps.

Run this in terminal:

apt install gnome-control-center
