replacing the uuid in /etc/initramfs-tools/conf.d/resume with the actual swap partition uuid fixed my problem
maybe that happened because I've had 9.10 with 10.04 and then I removed 9.10 and it seems that the swap was not enabled on Lucid and I enabled it manually. I don't remember what happened exactly but I usually told the second system to use the same swap of the first one. -- 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
