Hi,
I’ve upgraded my fedora KDE installation from 33 to 34 and I noticed that sound and wireless networking isn’t working properly. I’ve managed to do some digging and the source problem seems to be that User Manager service isn’t staring on login and XDG_SESSION_ID variable isn’t set at all.
Perhaps pam_systemd isn’t properly configured? I’ve taken a look in /etc/pam.d folder and *.rpmnew files look troubling…

After login i can start User manager service as root without problems, but it does not fix my desktop session.
