Bug 477073

Based on your description, it seems that you cannot log into the plasma session at all. Is that what is happening?
If so, can you log into the plasma session with the latest neon unstable iso?

As I said I get default login screen. 
Completing the information. Here I can select Wayland and login into it. The issue is that autologin to Wayland session configured long time ago stopped work. BTW. I did it manually in sddm config file and long time was working well.
Second problem is that in System Setting is not possible to set session Wayland for autologin - after apply always back to Plasma (X11).
Neon Unstable I installed, more or less when started development Plasma 6, and I try to update it daily.

Maybe this is the problem latest version of sddm?

I will update this post soon to let you know it this helped.

I think I will report another issue that configuration of sddm - part calling: "Login Screen (SDDM)" doesn't work in System Settings. Neither change of login screen nor configuration.

Seems above broke login screen. And I could not even enter the password.
Putting following seems doesn't break it:

The wayland session has been renamed to just plasma, instead of plasmawayland. Could you try that to see if it works?

Also, would you be able to provide your full sddm configurations?

OK. Let me check. I updated my configuration as you suggested. I will update this post, soon.

I'm not sure if this is what you needed, but check out below. And if this is not enough, tell me please where I can find more.

Using above configuration I get login screen.

And this is not Breeze stated in configuration, only one I set long time ago, and which actually doesn't work because it was dedicated for Plasma 5. It looks similar like one in post here (OpenMandriva forum): https://forum.openmandriva.org/t/sddm-login-screen-incorrect-after-upgrading-to-rome/4972 . Maybe this topic for another bug report.

So you are not automatically logged in as expected, right?

Could you try just keeping this:

[Autologin]
User=piotr
Session=plasma

and deleting everything else in your sddm configs and see if it automatically logs you in?

Also, could you manually select the wayland session and log in?

What is the output of "ls /usr/share/wayland-sessions/"?

Have you tried this? 

Also, when the automatic login did not happen, could you switch to a tty (ctrl-alt-4) and report the output of journalctl -b ?

Sorry I meant ctrl-alt-f4; use ctrl-alt-f1/2 to switch back

Had no tried. Only I removed almost all from directory /var/lib/sddm. I left only file "state.conf". Of course didn't help.
I will provide update soon.

Please find in attachment. BTW. In this case I could not login to Plasma Wayland even by login screen. Every time it had back to login screen.

Autologin still doesn't work. I'm not sure if this is because I could not login to Plasma by login screen.
I updated Plasma at 24/11/2023 and still could login to Plasma by login screen. I made test after this update.
Additionally I left only suggested configuration, so:

$ pwd
/usr/lib/sddm/sddm.conf.d
$ ls -l

-rw-r--r-- 1 root root 38 lis 23 01:11 00neon-autologin.conf

Looking at the logs, it seems that you still have got plasmawayland instead of plasma configured for autologin...
So I am tempted to close this as this seems like a configuration issue..

I provided you my configuration, and cleaned it you as you suggested, but without effect.
Anyway I found another files:
<cut>
$ cat /etc/sddm.conf.d/kde_settings.conf
[Autologin]
Relogin=false
Session=plasma
User=piotr

File ⁄etc⁄sddm.conf.txt  is empty

Today magically autologin started work.
One thing I have done was cleaning directory /etc/sddm.conf.d where was placed couple files, so:

$ ls -l
total 20
-rw-r--r-- 1 piotr piotr 275 nov 20 19:09 kde_settings.conf
-rw-r--r-- 1 root  root  161 may 25  2023 kde_settings.conf.bak
-rw-r--r-- 1 root  root  169 nov  6 00:24 kde_settings.conf.last-ok
-rw-r--r-- 1 piotr piotr 306 may 25  2023 kde_settings.conf.new
-rw-r--r-- 1 root  root  309 may 26  2023 kde_settings.conf.wayland_autologin

I left only kde_settings.conf. I made update and turned off my PC. Late evening turned on and turned out that I was able to login without password. Even login screen changed to the "breeze".

I don't know if this was result my cleaning or update helped. Anyway I'm going to close this bug report.

With very probability I think it was the result of cleaning the config folder...
I am glad you solved the issue!

By the way I checked `man sddm.conf`, and they were using all the files in /etc/sddm.conf.d !
