linux equivalence of Windows hibernation?

http://www.suspend2.net/

Software suspend 2 should be applied as a patch to the kernel. There is something called software suspend already in the kernel but I haven't had success with it. Software suspend 2 however works great after you setup everything according to their instructions (requires unloading certain modules etc before shutdown). It requires a little configuring and such.

Software suspend works with most of the DRI drivers. The ATI drivers for my radeon 9600 don't work with that. There is some tradeoffs. I wish they make implementing this easier in the future. As it is right now it's a pain in the rear imo.

Kernel 2.6 can do it by using some particular parameter at boot time...
I think it is resume=/dev/your/hibernate/partition in the lilo.conf append line.
The partition must be at least the size of you memory and swap type.
If it is not enough you can find some ressouces on google ;)
See you

This question also popped up in this thread:

My summary from there: using FC3 on a Dell D610, I ended up using swsusp2 (mentioned above) because I wasted so much time trying to get suspend to RAM working.

suspend to disk is autoconfigured on ubuntu 5.04, provided you install with a swap partition at leaqst as big as your ram. works quite nicely on my latitude d410.
