A slimmed down Ubuntu Gnome desktop with no applications other than Firefox installed. Adding GIMP and openoffice took another 560+Mb, but the installation is still just on 2Gb.

Method from a Distrowatch article based on Intrepid but all still works on Jaunty.

An answer on Ubuntuforums and a previous thread about pmi, a command line interface to power management tools, give me hope about being able to hibernate and suspend from a dwm on Xorg with no desktop manager system. See

I’d better explain

  • Stock Ubuntu: hibernate works when you set the Power Options settings so that the lid closed action is hibernate
  • Stock Ubuntu with a new session and a different window manager (e.g. dwm) close lid does not hibernate, but if you install pmi-interface you can issue a command from your user terminal ‘pmi action hibernate’ that will cause hibernation.
  • I’m now going to re-install a CLI system and install just pm-utils uswsusp acpi-support pmi-interface and see what happens. Can I hibernate from a CLI only system? Once I answer that question, some way of trapping the lid closing event will manifest itself.
