Suspending machine takes too long

[kyjo]

1) Ubuntu 16.04 and Ubuntu 16.10

2) pm-utils 1.4.1-16

3) I expect the machine to suspend without delay. On Ubuntu 15.10 the my machine used to suspend in 1-2 seconds.

4) It takes over 10 seconds before the machine is suspended.

I just noticed this only happens in the MATE environment. When I suspend from Gnome it suspends immediatelly.

Usually hooks are called to let everybody suspend, maybe in the Mate environment there are others active that slow things down?

Maybe debugging along [1] can help to spot the issue in more detail.

In general you'd want to try to track down what activity is running while this unexpected delay is going on. Since everything is freezing at that point you will have to setup logs to go to file and pick them up after resume.

With the current information there isn't enough to debug/help more - setting incomplete for now.
