Suspend takes >20 seconds

[Philipp Keck]

My ThinkPad X220 with Ubuntu 13.10 (upgraded from previous versions) takes 20 seconds or more to suspend. This wasn't the case with 13.04.

During those 20 seconds I can reactivate the screen (which turns off properly) and then login and use the laptop (until it suspends after some time). If I login before suspend, I don't have to login on resume.

The issue is present with all of these ways to suspend:
- closing the lid
- using the Unity menu -> "Suspend"
- sudo gdbus call -y -d org.freedesktop.login1 -o /org/freedesktop/login1 -m

Calling "sudo pm-suspend" on the other hand always works immediately. I can't use this as a workaround, because it doesn't ask for the password on resume.

For logs, see this bugreport: https://bugs.launchpad.net/ubuntu/+source/systemd-shim/+bug/1252121)
pm-utils version is 1.4.1-12ubuntu1

I don't know if this is designed like this on purpose or a (related?) bug: The login screen I get after resume is quite different from the one I get on normal startup (see other bug report for details on that).

Yes, that's the screensaver, while the initial one is lightdm.

As pm-suspend works, this is not a bug in pm-utils but somewhere in the higher levels. Can you please enable system D-BUS debugging as on https://wiki.ubuntu.com/DebuggingDBus and create/attach a system D-BUS debug log what happens when you run "sudo gdbus call -y -d org.freedesktop.login1 -o /org/freedesktop/login1 [...]" or just use the unity menu?

Thank you for your answer. I will try to do that, however I don't know much about D-BUS. I managed to activate the system bus logging and dbus-monitor outputs a lot now. However that's too much for my console window and it is without timestamps. How can I get a useful logfile that I can upload here?

[Philipp Keck (philipp-v)]

I attached a logfile (without timestamps, because I don't know how) that was recorded during "sudo gdbus call -y -d [...]", 30 seconds of waiting, resuming the computer from standby and entering the password.

This bug still occurs on my device,
