Actually, that seems like a regular problem across Linux, when people try to use NVIDIA drivers and encrypted file-system. Plymouth doesn't play well with NVIDIA.
The temporary solution is to disable splash screen during boot:
sudo nano /etc/default/grub
In editor, change GRUB_CMDLINE_LINUX_DEFAULT="splash quiet" to GRUB_CMDLINE_LINUX_DEFAULT="nosplash ...
First, install sudo apt-get install ecryptfs-utils cryptsetup. You'll need to encrypt your home folder while you are logged out, so u need to change account-it has to be account with sudo privileges.
Login to the other account.
Then run sudo ecryptfs-migrate-home -u user and replace user with name of your account (the one that you want to encrypt).
Open up a terminal and type:
sudo cryptsetup luksChangeKey /dev/sda5 -S 0
If you want to add another passphrase:
sudo cryptsetup luksAddKey /dev/sda5
If you want to see which keyslots are enabled:
sudo cryptsetup luksDump /dev/sda5
If you want to erase keyslot #1:
sudo cryptsetup luksRemoveKey /dev/sda5 -S 1
DO NOT erase the last remaining keyslot ...
Ok, it seems I've found the solution, but I'd like to see some confirmation because all this stuff seems complex and I see that has been changed multiple times with recent updates of Linux.
I understood that a file /etc/crypttab must exist and enumerate the devices to be unlocked at boot. Giving a custom partition scheme, the Elementary installer didn't ...
Right. There is a bug (filed here) that changing your password while your encrypted home directory is mounted doesn't also change the encryption password of that encrypted directory. (It's possible that's by design for security.)
But you should still have the command if you want to change the password of your partition. Assuming your password has already ...
It took me awhile to get around to resolving this, but in the end, I just backed up my documents and made a list of apps I had installed, then wiped the drive and installed Freya, choosing not to encrypt the drive when given the option.
Thanks for the input, all!
I encountered the same problem the other day. To update your encryption passphrase to match your login password, you need to use the ecryptfs-rewrap-passphrase command. There is a more detailed answer in my post here: https://elementaryos.stackexchange.com/a/7949/5722.
Furthermore, I have tried to replicate this issue but have been unable to. Using System ...
If you have the same thing, you can solve it without reinstalling the OS:
Boot your system in nornal mode
in the pantheon greeter prompt pressCtrl+Alt+F1 to drop to TTY1
login with your new password
change your password yo previous.
Unfortunately, i don't know how to change \home folder encryption passkey.(
