I have an older Thinkpad X30 on which suspend-to-RAM (standby) and suspend-to-disk (hibernate) work perfectly.

In Windows XP, after an hour of standby, the machine will wake up and hibernate. This is a great battery saver, and quite convenient.

Is it possible to do the same in Linux?

Yes, you can use Suspend2 for Linux. It is included with recent kernels. You'll need to get the hibernate scripts from the site tho:

I've been meaning to try this, let me know if you have any luck with it.

I've got Suspend2 working on a Compaq Presario 2715US with Archlinux (using the -beyond pre-compiled kernel). It works fine for the most part, but I'm still trying to debug it.

1) If I let it have access to change the Grub menu, it'll corrupt the menu if something goes wrong.
2) If I hibernate and then immediately resume, I have no problem. But if I wait a couple hours, it never restores the screen. I thought that it was hung, but it's not. It's all there, just the screen isn't on. I thought it might have something to do with my network drives changing while it's unconcious, so I changed hibernate.conf to unmount and remount the network drives and use "hibernate -f" and so far no problems, but I haven't given it a real test yet.
