Subject: Hibernating under Linux ...


One of the few things I think Windows does well (well, definitely
better than "us") is hibernating. You can actually notice how the hard
drives don't seem to be powered and even the fans stop spipping

I have tried hibernating under both, knoppix 6.2 and Ubuntu 9.10 and
none of them get it right. Is there any Linux distro that does?

Why is that?

Thanks

You didn't give any details on your hardware, or on exactly what's
happening on your system. However, normally "hibernate" should be a full
power-down.

Both suspend-to-ram and suspend-to-disk result in fan and hard drive
poweroff on my hardware (dell inspiron 1420 laptop running ubuntu
9.10). It would be easier to help you if you gave details on your
hardware, and how you're triggering the suspend.

I should note that knoppix (or any other livecd distro) won't be
capable of suspend-to-disk (hibernation as windows calls it);
hibernation involves saving all state to disk and doing a full power
off, and when the whole point of the distro is to _not_ use the disk,
you clearly can't do this. Suspend-to-ram should work however, and on
most hardware should power down the hdd and fans.
