Hibernation quit working

[overshoot]

After a recent disk migration and update (mostly new KDE) everything is working nicely except hibernation and KDE shutdown (a longstanding problem not related to this -- I think)

Kernel was not changed in the migration.

In brief: hibernation refuses to save for want of a swap -- but there swap is:

dragon hibernate # grep CONFIG_PM_STD_PARTITION /usr/src/linux/.config
CONFIG_PM_STD_PARTITION="/dev/sda7"
dragon hibernate # swapon -s
Filename Type Size Used Priority
/dev/sda7 partition 8388604 0 -1

OK, WTF? Why is s2disk claiming no swap device?

there's a good hibernation howto at: https://forums.gentoo.org/viewtopic-t-958028-highlight-tuxonice+perfect.html. i don't use kde so i'm not sure, but it looks as though kde and hibernation don't work out-of-the-box without some tweaking: perhaps the howto there contains the fix?

What is the resume device file set to?

beats me then. you're getting that from /usr/sbin/s2disk, which i don't even have on my system (and hibernate works perfectly). /me shrugs

I only use tuxonice so pardon if this comment is ignorant.

Could it be that s2disk is looking for a *file* and you have
a *partition* (in tuxonice hib to swap and hib to file are
quite different) ...

Thanks for the hints, people -- but going back over the emerge.log I found sys-power/suspend and there was s2disk.
So I tried uninstalling it and lo! Hibernation now works. Suspend, no -- but at least hibernation does.

Then there's the perennial problem with KDE not shutting down the execrable akonadi before it launches
shutdown, and thus leaves the /home volume mounted and busy. Wish they'd get that properly fixed do I don't have to
make a two-step process out of shutting down the box, but that's another problem for another day.
