[Bug 2039340] Re: On upgrade from 23.04 to 23.10, cannot login using Gnome or Ubuntu WM entries

[Steve Langasek]

What is the behavior when you try to log in?  Do you get an
authentication failure message, or does it appear there is a successful
login followed by a screen flicker and a return to the login screen?

Are there failure messages in /var/log/auth.log?

Bug description:
  Last time I hacked around a bug like this, it had portions in PAM,
  apparmor, Seahorse, and Gnome so this time I'd like someone more
  focused on broad stability to look at things.

  The problem is simple.  Before the upgrade to 23.10, I could log in
  using the "Ubuntu", "Ubuntu on X.org". "Gnome", and "Gnome on X.org"
  WMs.  Now I can't.  I can still login using XFCE and TTY.
