I suddenly started experiencing this issue on Kubuntu 22.04.1 a few months after upgrading from 20.04 LTS. After pulling out most of my hair, I also discovered that pam was closing unexpectedly, causing the greeter to stop, and that that was the reason that sddm became unresponsive.
I came upon a workaround suggested in github sddm issue #1443: loginctl enable-linger Using this prevents pam from closing out (and me from losing the remainder of my hair). I hope that the cause of pam closing out can be found, or that sddm is updated to detect that the greeter has stopped without a user logging in. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to sddm in Ubuntu. https://bugs.launchpad.net/bugs/1893302 Title: SDDM freezes on system boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sddm/+bug/1893302/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
