I had the same problem. My laptop suspended fine when invoked from the keyboard (fn+power key) but not with the powermanager when idle, I found it always blocked with the message "powermanager : not authorized" when I came back.

Hi all,
I had the same problem. My laptop suspended fine when invoked from the keyboard (fn+power key) but not with the powermanager when idle, I found it always blocked with the message "powermanager : not authorized" when I came back.
Thanks to your clue with light-locker, it seems that the following fixed the problem permanently for me:
sudo aptitude purge light-locker light-locker- settings settings
sudo aptitude install light-locker light-locker-
I believe that removing and then re-installing fixed a policy problem somewhere.
Hope this will help...
Cheers,
