[Bug 1239004] [NEW] Cannot enter full disk encryption passphrase on Lenovo Helix in tablet mode

[Donn Morrison]

Public bug reported:

Fresh install of 13.10, selected full disk encryption.

The Lenovo Helix turns into a tablet by detaching from the keyboard. If
the system is rebooted while you are away from the keyboard (e.g., you
leave it at home) you cannot enter the passphrase. I suspect this is or
will become a problem for other tablets. I could not find any
information about a workaround through searching except for storing a
key on a USB stick and modifying initrd to read this at boot.

Obviously implementing an onscreen keyboard for the console at boot
seems a bit far fetched. Is there any idea for a workaround?

Description:    Ubuntu Saucy Salamander (development branch)
Release:    13.10
