Hi Daniel, unfortunately, there are no crash files in /var/crash/. I've checked also: https://errors.ubuntu.com/user/<whoopsie-id> but there are no crashes reported in the last month.
It looks like the "crash" is not caused by a fatal signal like SIGSEGV and no core dump is generated. But, still from the same log file (attached), I noticed that systemd- logind exited with a failure: ---------------------------------------------------------------------------------------------- Nov 10 00:20:13 lenovo upowerd[3602]: Could not acquire inhibitor lock: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Nov 10 00:20:13 lenovo dbus-daemon[1120]: [system] Activating via systemd: service name='org.freedesktop.login1' unit='dbus-org.freedesktop.login1.service' requested by ':1.178' (uid=1000 pid=12386 comm="/usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/use" label="unconfined") Nov 10 00:20:13 lenovo gsd-power[12749]: Unable to inhibit suspend: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Nov 10 00:20:13 lenovo gsd-media-keys[12746]: Unable to inhibit suspend: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying Nov 10 00:20:13 lenovo systemd[1]: Starting SSSD PAM Service responder...
