Login manager and users GUI are gone

[Georgie-o]

Did a new install of Ubuntu Mate 22.04 on a Dell XPS laptop. Looked like everything was working great. Went to add a new user and saw the icon was not present. Added the gnome tools and got that to work. I also noticed that I can't find the icon to changed the login screen... It's not there. Is this a bug that's being fixed? Any easy solution?

Thanks

Good question.

Here are some links with explanations about this problem and also some workarounds:

How do I change Login Screen wallpaper in Ubuntu 21.04?

Because they switched to a new greeter in 20.10 compatible with Ayatana Indicators and there's no GUI to change those setting yet. Reasons are mentioned in the 20.10 release notes. There's a reason interim releases aren't LTS. They're paving the way for the next LTS, introducing new features, one at a time and things aren't expected to be perfectly polished. You can edit the Arctica Greeter settings with: sudo pluma /usr/share/glib-2.0/schemas/30_ubuntu-mate.gschema.override Don't screw u…

Here is a perfect working solution by reverting to slick-greeter:

Replace arctica-greeter back to slick-greeter on 20.10 for better compatibilty with other desktop environments

Some Ubuntu MATE users report incompatibilities between Ubuntu MATE 20.10 login screen and other window managers as i3. This question was asked today on AskUbuntu. Technically it is a bug of arctica-greeter. It ignores selection of i3 and loads MATE instead. I have reported the bug 1910279 to LaunchPad and upstream. This bug is not only i3-related, other desktops like Xfce are affected too. The workaround is to revert our latest change: replace Arctica Greeter back to Slick Greeter. sudo ap…

Extra background info and some workarounds for if you want to keep using 'Arctica' greeter, in the following thread are several ways to bypass some of the problems:

How to change login screen background?

Some things changed under the hood which resulted in a bug. See this: and this: and the "won't fix" answer of the author. so you have to edit a configfile manually: sudo pluma /usr/share/glib-2.0/schemas/30_ubuntu-mate.gschema.override and change the background= entry then recompile the schemas: sudo glib-compile-schemas /usr/share/glib-2.0/schemas/. This seems to be the accepted workaround for the time being. It lacks a bit in elegance I'm afraid. But it works pretty well.

Hallo out there. I made a new installation of Ubuntu MATE 22.04. All works fine BUT i missing the option to manage users and groups. Is there no other way than to install the gnome-system-tools like Georgie-o said? Has the Mate control center no own GUI or tool? I can't believe that... Or is there something wrong with my installation?

Thanks for help or hints

Unfortunately, as far as I can tell, that is correct: in Ubuntu MATE 22.04 ("Jammy Jellyfish"), if you want a GUI Tool to manage users and groups, you have to install gnome-system-tools. In Ubuntu MATE 22.10 ("Kinetic Kudu") there's a new tool called "User Manager" that replaces the gnome-system-tools that had been removed from Ubuntu MATE 22.04

From the "Ubuntu MATE 22.10 Release Notes | Ubuntu MATE" posted by @Wimpy (Martin Wimpress) himself:

"(...) MATE User Manager

A new utility, User Manager, has been added to complement the suite of MATE tools. User Manager replaces the aging gnome-system-tools which was removed from Ubuntu MATE in the 22.04 release and allows you to add/modify/remove user accounts. It also includes the ability to define which users are Administrators, enable/disable auto-login, set profile images and manage group memberships.
