Where can I find info on energy saving options for Kubuntu?
There doesn't seem to be anything on the Hardy guide[1].

I've installed Kubuntu 8.04.1 on a few machines. Hibernate appears as an
option in the log off dialog box, and sometimes suspend is also an option.
But these don't seem to work. Could be I'm not using them correctly, or
there is some configuration needed.
On one box I tried, hibernate closed the PC down, but when it resumed, there
was no sound.
