I can hibernate with s2disk, so this seems to be set up correctly. In /etc/pm/config.d/00_sleep-module, I have the line SLEEP_MODULE="uswsusp", which should make the system use uswsusp for hibernation.

However, if I choose ‘Ruhezustand’ from the system menu (that’s hibernation in a German locale), it just does not work. I even see the warning about the missing splash system (which I always ignored). When called by hand, this is followed by the textual progress meter, but when called from the menu, that’s where it stucks. I cannot even imagine how to debug that.

It used to work before I upgraded to 11.04, so it is connected to the update somehow.


  • running pm-hibernate as root works
  • running sudo s2disk works
  • however, sudo pm-hibernate fails

Now this is weird. Something in my environment makes pm-hibernate fail?

What about pm-hibernate? – psusi May 11 '11 at 15:01
I didn’t know aboud pm-hibernate, but it allowed me a few more tests. Thanks @psusi for pointing me at it. – MPi May 12 '11 at 6:55
pm-hibernate works most of the time. – MPi Sep 29 '11 at 7:08
