Recently the "suspend" and "hibernate" options have disappeared from gnome's logout dialog (a good thing). I tried hibernating with 20-6.11 by stopping X (/etc/init.d/gdm stop), unloading the nvidia driver (sudo rmmod nvidia) and echo "disk" > /sys/power/state . It still fails.
What happens when doing the above is that the machine shuts down normally, but when I turn it back on, it proceeds to a clean boot (i.e. doesn't even attempt to come back from hibernate). This seems to be happening because my swap partition gets corrupted. I noticed this because after "hibernation", I have no swap space and "swapon /dev/sda5" fails with "invalid argument". To restore it, I have to "mkswap" again. Here's a kern.log, I hope it's of any use. ** Attachment added: "kern.log" http://librarian.launchpad.net/6073856/kern.log -- Fails to hibernate https://launchpad.net/bugs/81189 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
