My hibernate stopped working after a fresh install of 10.04. Symptoms were that it would appear to hibernate correctly, but on restart would just boot to the login screen and once I logged in networking was disabled.
Following the above I had a look at /etc/initramfs-tools/conf.d/resume - it didn't exist. I ran: sudo update-initramfs -u and it didn't generate any errors but that file still didn't exist afterwards. I manually populated the file with: RESUME=UUID=7482c5cb-6168-45dd-bfce-041561c80512 and ran the update command again. It said: update-initramfs: Generating /boot/initrd.img-2.6.32-23-generic cryptsetup: WARNING: found more than one resume device candidate: /dev/sdb5 UUID=7482c5cb-6168-45dd-bfce-041561c80512 These are both the same device, although my fstab refers to the swap device by UUID. Anyway, I hibernated and this time it worked - I got a 'resuming' message on the boot screen after the grub menu. So I suspect my problem was some sort of mismatch over the swap partition name, though I have no idea how it came about. For what it's worth, I left my old partitions in place (originally created by an Ubuntu installed back in 2005/2006 - I did in-place upgrades until this time) when I installed 10.04. The installer refused to recognise my swap partition (I cannot remember the details, I'm afraid) and I had to do the install without swap (no problem as I have 2GB RAM) and manually add the swap myself afterwards. So maybe I added it badly, I suspect I copied the /etc/fstab line from the backup I had taken before the reinstall (left to my own devices I would probably just have called it /dev/sdb5) but I can no longer be sure. Sorry this is a bit vague but I thought the information just might be useful. And thanks to the guys above for pointing me in the direction of a solution. -- lucid regression: does not resume from hibernation https://bugs.launchpad.net/bugs/577916 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
