I am also experiencing the same problem on 15.04. It use to work and then after one of those software update (I don't remember which one) it would now not let me type my password for decrypting the hdd. I would have to power off and power on again, see grub choose Ubuntu and then it would go into the non graphical prompt (still purple) which would allow me to enter the password and proceed to the normal log in screen.
