How to graphically enter Password to unlock encrypted disk
Is there some way I can unlock my btrfs encrypted disk using a graphical unlocking screen.
Basically I was setting up an On-screen keyboard so that I can use my PC in case I do not have a keyboard available. Only problem in setup is that I can't find anyway to use on-screen keyboard on that screen on which we enter password to decrypt disk.
They're using full disk encryption, which won't let any part of it be read (even its partition table to boot the OS) until a password is entered. A system using FDE will go straight from POST to a password prompt.
A lot of people like FDE as it makes the encryption completely invisible to the OS and would normally have zero compatibility issues be problem-free.
