In Slackware, hibernation works out-of-the-box and can be easily done from KDE's menu. Resuming from hibernation, however, is not set up, so when you turn on your computer again, it starts as normal. That is, if your hardware supports it and if you've set up a swap space larger than your RAM.

Huge kernel

To tell your kernel where to resume from, you need to write the info to lilo.conf:

append=" resume=/dev/sda6"

Replace /dev/sda6 with your actual swap space. Swap partitions are perfect, I think swap files should work too. If you don't know where your swap lies, look at /proc/swaps.

Generic kernel + initrd

If you're using generic or your own kernel, you need to adjust initrd image as well. Append

 -h /dev/sdx

to mkinitrd command so it may look like this:

 mkinitrd -c -k 2.6.33.4 -f <fs_type> -m <fs_type> -r /dev/sdx -h /dev/sdy

Replace /dev/sdx with your actual root partition and /dev/sdy with your actual swap space.

If you're using LVM, don't forget to append -L to mkinitrd command

 mkinitrd -c -k 2.6.33.4 -f <fs_type> -m <fs_type> -r /dev/sdx -h /dev/volumegroup/swap -L

Afterwards, run lilo.
