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.
Not sure thats possible. But there are some workarounds like using a keyfile on a usb or a yubikey which can output a static password on longpress. Or some other hack-around.
Some relevant search results, the first one seems especially promising:
