Public bug reported:
When no swap is active, the 'hibernate' item does not show up in the
/system/ menu.
I manually verified that hibernation works on my machine (using pm-
hibernate), and it does.
As I am using an SSD, I do not use any swap at all (I have enough RAM).
However, I have an inactive swap partition that gets activated by a pm hook:
> cat /etc/pm/sleep.d/00-swap
> #!/bin/sh
>
> swap_device="$( awk '$0 ~ /^#/ { next; }
> $3=="swap" {
> printf( "%s\n", $1 );
> }' /etc/fstab )"
>
> case "${1}" in
> hibernate)
> # Create and activate a clean swap
> mkswap "${swap_device}"
> swapon "${swap_device}"
> ;;
> thaw)
> swapoff "${swap_device}"
> # Forget the old SWSUSP image after resuming
> dd if=/dev/zero of="${swap_device}" bs=1048576 count=4
> ;;
> esac
Note: I need to cleanup the previous SWSUSP image, so the kernel does
not pick it up after a normal, non-hibernate boot.
If I manually activate the swap partition, then 'hibernate' shows up in
the system menu. If the swap partition is not active, but only
formatted, hibernate is not available; the swap has to be active.
It somehow makes sense to disable hibernate if there is no swap, but
using swap on an SSD risks wearing out the SSD very fast.
