I installed Ubuntu 11.10 using the alternate CD and set up an ecrypted root and swap partition. Now, during boot, I have to enter a password for the root and a passwort for the swap partitition. I want to get rid of the password for the swap partition and replace it by a keyfile that's stored on the root partition. How can this be done? Is there maybe some hidden option in Ubuntu so I don't have to configure this in some configuration files? Thanks for any help!

Could you add the contents of your /etc/crypttab? If it contains sensitive informations make sure, they are blanked out. –  qbi Apr 7 '12 at 21:08

I think it needs to be this way by design - 2 passwords.

After the initial boot up where you enter 2 passwords from then on you can use hibernate mode securely.

When you resume from hibernation it's just the one password.

You have to reinstall. I forget the terms, but you want one encrypted physical partition and then you just put LVM (maybe?) partitions on top of this one.
