I seem to be able to hibernate OK using s2disk, but when I switch the laptop back on, it seems to hang half-way through the "resuming" menu. The splash screen looks healthy, it seems to be trying to resume from the correct disk, but it hangs about half-way through, with three little pips.

One great help would be - where can I find the logs, and how do I get more verbose ones?

There is some info in /var/log/pm-suspend.log, but that all seems fine, just lots of hibernate: success messages...

How do I switch on more verbose logging in s2disk? And what about the resume process, where are the logs for that, and how can I make them more detailed?

Background: the standard Ubuntu hibernate wouldn't work, so I've install uswusp and its associated tools - s2disk etc. That initially made things worse, but a fair amount of fiddling with its config, my swap size and so on seem to have got it at least seemingly successfully suspending...

[update] some config info:

RAM: 8GB swap space: 8.63GiB (NB i did try increasing swap to 16GB, didn't help)

$ sudo blkid
/dev/sda: TYPE="isw_raid_member" 
/dev/zram0: UUID="45e58d74-be57-4ad4-95de-217e9ba7d087" TYPE="swap" 
/dev/sdb: TYPE="isw_raid_member"

/dev/mapper/isw_dgibfidibf_Volume0p6: LABEL="SHARED" UUID="10BA-FE58" TYPE="vfat" 

$ cat /etc/initramfs-tools/conf.d/resume
RESUME=/dev/mapper/isw_dgibfidibf_Volume0p5

try removing cryptsetup from your system, worked for me.

This answer may not be helpful for around 7 days, but I had a similar problem with hibernate and sleep and when I upgraded to Ubuntu 12.04 Beta all issues were solved. So I'd suggest either simply waiting till April 26th and upgrade then or Installing Ubuntu 12.04 Beta.

Hope this helps.

  • Though you would need to reenable it as hibernate is disabled by default in 12.04 as far as I know. Would be interesting to know what RAM and swap you actually have. – 23 93 26 35 19 57 3 89 Apr 19 '12 at 18:02
  • Good point I hadn't even noticed, the last time I hibernated must have been before they changed that! Also I have 1GB RAM and 2GB swap :) – Ross Fleming Apr 19 '12 at 19:25
  • nope, just upgraded to 12.04 beta yesterday, and if anything hibernate is even worse - it doesn't even get as far as shutting down now, just sticks at freezing processes – hwjp Apr 20 '12 at 08:32
