Can't login after today update

Starts X11 login, take password and return to login screen.
In a string login - all is OK.

Re: Can't login after today update

I'm assuming a 'string login' means a TTY? Share the journal from a boot where this behaviour occurs.

Mod note: moving to NC.

What is a "string login"?

take password and return to login screen

typically means the session crashes, check your system journal "sudo journalctl -b"

Re: Can't login after today update

I certainly don't either…
Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: Can't login after today update

Wtf?
There's only one participant leading monologues here…

Use deepl.com to get over the language barrier, see the linked arch news, make sure to (re-)install the plasma X11 session and fix KMS if you want to use wayland instead.

Re: Can't login after today update

I don't need any wayland, my setup is X11 session and I don't know what is this string.

Re: Can't login after today update

Yes I know, so I'll link it again: https://archlinux.org/news/plasma-640-w … re-on-x11/
You didn't do this, so you end up trying to start a wayland session what fails because the nvidia driver isn't sufficiently configured for that (which btw: you want KMS support wayland or not)

Re: Can't login after today update

Ok, but you're not trying to log into an X11 session in the provided log.
Have you explicitly selected plasma on X11 and tried to log into that?
What does the journal fort that attempt look like?

Re: Can't login after today update

I've no idea what you're talking about, but plymouth is the splash screen you see before SDDM shows up.
It's not been related to session startup failures.
You were trying to start a wayland session and that failed because nvidia_drm.modeset wasn't enabled. That's all.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
