I just installed Ubuntu 13.10 with the full disk encryption option selected. This asks me for a password before Ubuntu even starts. I figure since I am already entering one password I could automatically login skipping the login password, however, this option does not seem to exist anymore. Is this feature gone or is it disabled because of the encryption or what?
Encrypt my home folder
If you choose this option, be careful not to enable automatic login at a later date. It will cause complications with your encrypted home folder, and will potentially lock you out of important ﬁles.
