Is there any way to find out which device/event caused Ubuntu (10.10) to wake up from the most recent sleep/hibernation?
I am trying to troubleshoot some sleep issues on a new box, and knowing what's causing it to wake up would help.
I did check
/var/log/pm-suspend.log but all it seems to say is
Sat Dec 11 22:18:27 GMT 2010: Awake.
which isn't terribly helpful.
