Public bug reported: When screensaver is on, I often can't wake the system back up again. Screen comes, up, clock shows but frozen and login does nothing.
I have a file `/var/crash/_usr_lib_systemd_systemd.0.crash` from around the incident time, so I guess it's systemd itself that's crashing. Trying to dig into the crash report, this is how far I get: ``` $ gdb `cat ExecutablePath` CoreDump GNU gdb (Ubuntu 11.1-0ubuntu2) 11.1 Copyright (C) 2021 Free Software Foundation, Inc.
