[Bug 1980679] Re: Suspend on focal takes 30s.

[Nick Rosbrook]

Is this still an issue? If so, what does the output of systemd-inhibit
show? Please also attach logs from journalctl from the time between
suspend is initiated, to the time it actually takes place. Finally, if
you have any changes to logind's config, that would be good to know:

$ systemd-analyze cat-config systemd/logind.conf

Title:
  Suspend on focal takes 30s.

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  Just upgrades my NUC from Bionic to Focal and suspend went from
  immediate (within a couple seconds) to taking a whole 30 seconds.
  While suspend is happening, the machine is still usable, mouse moves,
  applications respond, all the way until the machine actually goes to
  sleep. I don't see anything strange in kern.log that would explain the
  slowness:

  There does look to be 30s between the last "Lockdown: systemd-logind:
  hibernation is restricted; see man kernel_lockdown.7" and "PM: suspend
  entry (s2idle)"

  This is mostly a frustration, but could be a security issue for some
  if they suspend the machine and walk away thinking it would be locked
  but is usable for another 30s.
