Cannot authenticate with version 6.13
Description:
Every attempt to enter a password on the log screen results in "Authentication failed" when running xscreensaver 6.13
Additional info:
I'm running systemd-homed with a btrfs subvolume as storage backend. The /etc/pam.d/system-{auth,login,local-login} are the ones from pambase and log in on GDM on TTYs and other authentication attempts e.g. for run0 work without a problem.
The update to 6.13 coincided with the update of systemd to 258.3, but downgrading systemd to 258.2, while keeping 6.13 doesn't change anything about the problem, but selectively downgrading xscreensaver to 6.10 while keeping everything else at the newest version allows authentication at the lock screen. I mention this because of a message a line in the logs below from homed.
The logs from xscreensaver restart, lock, login attempt and if necessary killing xscreensaver
