"Supported since Ubuntu 9.04 has been the ability to encrypt the
entire home directory of a user, either when using the Ubiquity
desktop installer or the alternate/server installer. The home
directory encryption is done over eCryptfs and the user's directory
is automatically un-encrypted when entering the user password for
their account. Only the user-data is protected, which is most
important, but the rest of the file-system remains open.
The original option for disk encryption in Ubuntu was around
since Ubuntu 7.10 and that is using a fully encrypted LVM.
Unfortunately, to this day, the option is only available from the
Ubuntu alternate/server installer. There is still no easy way from
the standard desktop installer to setup a fully encrypted LVM.
