I might have made some progress on this. Reading this post: http://ubuntuforums.org/showpost.php?p=5168992&postcount=5 gave me the idea to check if my initramfs was incorrect. It turns out that my initramfs is missing the file conf/conf.d/resume.
I presume that this is because when I installed I didn't use swap. I have 3 GB of RAM, so the only use I have for swap is for hibernation-- but I didn't know that swap was necessary for hibernation when I installed. I now have 3 GB of swap, but I haven't been able to find any documentation on how to rebuild initrd.img-2.6.24-19-generic with the proper resume information. I Googled this, but all I found was some kernel documentation and a Gentoo wiki page. The kernel docs were above my head (I know virtually nothing about the kernel), and the Gentoo page appeared to use Gentoo-specific commands. Later note: I just found the Debian kernel handbook page on initramfs, but if it answers my questions, I'm too dense to find the answer. I don't think I'm trying to generate a new initramfs using the method detailed there. I'm trying to change my existing one (or replace it with one that I altered). I think there are two issues here: 1. There should be some documentation about avoiding this situation, along with how to fix it. 2. Changes to swap configuration should be automatically detected, and initramfs should be updated automatically. I have no idea how difficult this would be. Perhaps it's infeasible at present. But it really should be automated. While I realize that this isn't a support forum, I would appreciate suggestions as to how to rectify this situation. You could consider it part of the documentation. :) -- ThinkPad R61i won't resume from hibernation https://bugs.launchpad.net/bugs/240605 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
