Public bug reported:
For a few weeks now (unfortunately, I don't know the kernel version in
which that changed) my laptop suspends randomly.
Googling leads me to suspect that ACPI lid events are sent under the
wrong conditions, as journalctl does not record any key presses that
might trigger the suspend:
$ journalctl -f -b -u systemd-logind

Jan 22 15:27:09 systemd-logind[1279]: Lid opened.
Jan 22 15:27:21 systemd-logind[1279]: Operation 'sleep' finished.
FWIW, I *do* get this in the morning when I opened up my laptop:
Jan 19 07:53:56 kernel: ACPI: Lid Switch [LID]
But that's not happening at any time during the above systemd log lines.
That's got me to consider that maybe it is a systemd/logind issue after
all.
What can I send you to help with the investigation?
Thanks,
Jens
