X31 Hibernate in Ubuntu Gutsy

[bobbarker]

I've tried a few different 'solutions' I've seen, some specific for the X31 and some not. From the general lack of recent information my guess is it works for most people. If you've got working hibernate on an X31 please post up your /etc/default/acpi-support and /etc/acpi/hibernate.sh files so I can try them out.

Tried it and oddly enough it doesn't work with me in Ubuntu 7.10 either. It writes out the data to disk, but when it comes to loading it up again, it acts like the data isn't there, and also disables swap. Is that the same that happens with you?

On the bright side, it worked perfectly with 8.04 alpha.

[bobbarker]

Back in 7.04 it would do that for me, now it starts to write data (the screen goes away) and the terminal flashes up momentarily then returns straight to the desktop. Hopefully 8.04 will fix it.

The screen-flash-without-turnoff usually means the swap is disabled. I had to reformat the swap every time I made a hibernation attempt, otherwise it wouldn't even get to the turning off part. But then you have update /etc/fstab since the uuid identifier of the swap changes when you format it.

[bobbarker]

The bad swap might be the problem since I deactivated (and recently removed) my swap partition. I never get above 500MB of ram use, anyway, why bother with swap...well I guess I should repartition my drives again and add swap back.

Anyways, on my end it just turned out to be because of my having both Hardy and Gutsy on there, which mixed up the swap UUID, which lead to poking around in two different grub.conf files... It works now.

As far as I can tell bobbarker's problem was simply not having a swap partition.

[bobbarker]

I made a swapfile (gotta love dd) and threw it in to fstab-- I'll try those conf files once I finish rebuilding my battery (cells just arrived today).

I believe it must be a partition, not a file.
