Help:Suspend and hibernate
From Openbox
Although suspend is not given as an option on the logout menu, it can be done. At the command line, enter:
- pm-suspend
(This works in systems including Mandriva, Arch Linux and Debian-based systems - is it a universal Linux command?)
Adding suspend and hibernate buttons at logout
A new package has been created as an alternative to the current openbox-logout script. It is a script which adds additional buttons for "Hibernate" and "Suspend" at logout. It may give mixed results with actually using these features. See New Logout Script with Hibernate & Suspend Options (Help & Support, CrunchBang Linux Forums, thread started 2008-12-03)
