Helo
Eu tenho uma nova instalação de 14.04
em um laptop com um disco SSD
. Ao instalar, eu ativei Full Disk Encryption , bem como criptografia da pasta home .
O particionamento foi deixado para o instalador sem alterações feitas por mim.
Alguém saberia porque minha troca não está sendo ativada e como corrigi-la?
