[ltp] Hibernate Partitions on R32?

[Jon Dick]

Hi, I also have an R32.

You -can- get the special keys to work. I can't remember where I saw
this and I haven't yet done it myself, but I know they do work eg. so
you can use the volume up/down buttons, not just mute.

That's suspend, not hibernate. Hibernate is where the contents of RAM
are saved to disk and the machine turns off completely (Fn-F12). In
suspend you will have a little green moon symbol still on, whereas with
hibernate nothing is on because it's really off.

What you need is a hibernate file on a FAT32 partition, unfortunately. I
think there is also a kernel patch for hibernating but I don't know if
it's any good.

When I got my notebook I did a clean installation of Windows XP on a
FAT32 partition as /dev/hda1. Then I used the bootable ISO image
available at [2] to create the hibernate file. Then from within Linux,
pressing Fn-F12 saves the state and switches off. It works fine but is
not quite as nice as doing it in Windows XP.

You have lost a little functionality. I couldn't live without hibernate!
