Is there a way to add (and use) new desktop/kde user ?
Brunhylde 27 Jul
Hello Linux lovers !

I would like to know if there is a way to log in desktop/kde with another user than the default user named "deck".

I can already create a new user with useradd command or kde panel configuration, either way.

But I don't know how to log in this new user in graphical mode (kde). I can connect it in the terminal (su new_user). How can I log out "deck" user from kde then log in with another user ?

P.S. : I'm a regular linux user so i can do basic linux stuff (cli command, vi editor, systemctl usage ...)

Thanks !

At login screen you can scroll (horizontally) through registered users using the left and right arrows next to your user avatar. That's the way on vanilla KDE 5.20.5 on Debian Bullseye. Other distros may have their custom login screens.

Thanks for answering, but, my concern is specific to SteamOS 3 on Steam Deck device. I should have explicit this on my first post. Sorry about that.

Quoting: BrunhyldeI can already create a new user
Don't. There is some stuff oriented around the "deck" user. I can't even understand how you created a new user since the filesystem is read only.
2. Probably autologin is enabled.
3. Prepare to redo entire setup process.

The /home section is not read-only (it must be a place to save your personal data). I just define a password for "deck" user to access sudo command and type in "sudo useradd new_user". So, there is no need to disable the read-only protection to add a new user.

From the Steam Deck Faq :

QuoteHow do I run sudo commands?

The default deck user is shipped with no password. This is a secure setting that prevents access via ssh, and can't be used to run commands via sudo.

If you’d like to set a password in order to run sudo commands, open a terminal window and set a secure password using the passwd command. At that point you will be able to use sudo anywhere elevation is required.

Anyway, I think your right, "There is some stuff oriented around the "deck" user", so I prefer don't change anything by myself for now. I hoped someone more skilled than I am found a secure way to disable autologin or just change the user auto-logged (I guess in /etc/sddm.conf.d/autologin.conf).
