thanks for your advice. The hdisk-stuff is the only thing I’s not really sure about. It’s great to hear your hard disk spin down and actually my hard disk seems to be optimised for this setting: it comes up within less than a second. But when you think about it, it doesn’t look that healthy. I’ll play around with it, maybe it’s better to only use the „quiet“ setting.

For the usb stuff: keyboard and touchpad are working with one exception: The hotkey for screen brightness is disabled which is not a great pity as I need it quite dark when saving power (and can, of course, reactive usb when needed).

Thanks for your comment and greetings,

ccm.

You can also use relatime instead of noatime on Gutsy for decreased atime disk IO while still keeping atime records (some apps like mutt freak out if your don’t use atime)

Also, several newer laptops have their keyboard/trackpad hooked up internally via USB, so warn that disabling USB might lead to no input devices functioning, needing a hard reset to get back in!
