Hello, I find a way to get it back. Please, follow the steps:
1) install hibernate if not already done: sudo apt-get install hibernate 2) check you have a swap partition large enoughs (depending of your usage but the RAM size is quite good) 3) find the swap partition UUID: sudo blkid | grep swap You might have an output like this: /dev/mapper/Vostro1220-lvSwap: UUID="12345679-1234-1234-1234-1234567890ab" TYPE="swap" 4) register the RESUME UUID replace the 12345679-1234-1234-1234-1234567890ab by yours: sudo -i # become root echo RESUME=UUID=12345679-1234-1234-1234-1234567890ab > /etc/initramfs-tools/conf.d/resume logout 5) refresh initramfs: sudo update-initramfs -u -k all Enjoy the suspend to disk :D Regards, Damien -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/802152 Title: Natty laptop doesn't resume after hibernate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/802152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
