Bug Description

I set up a fresh ubuntu with the alternate installer. I have a separate /boot, an encrypted partition for LVM and an encrypted partition for swap.

At boot, I'm asked my passphrase for the encrypted LVM partition. I briefly see a prompt for a passphrase for my swap, but then lightdm takes over and gives me a logon prompt.

If I manually setup the correct mapping for the swap partition, I can (obviously) manually issue a swapon -a.

You don't say what the mountpoint is for the filesystems on your encrypted LVM partition; but evidently they aren't any of the standard mountpoints that are considered blockers for starting lightdm.

The behavior in this case is expected - this is not a bug but a misconfiguration. If you want launching lightdm to wait until these filesystems are decrypted, you will need to mark those filesystems 'bootwait' in /etc/fstab.

I suggest this *IS* a bug, even multiple bugs, for the following reasons
* The bootwait option does not seem to work in this case
* It may make sense not to wait for fsck, but not for asking passwords, it'll never complete.

Ok, then if bootwait isn't working, this appears to be a mountall bug rather than a bug in cryptsetup.

My partitions look like this:

 LUKS -> LVM -> ( ROOT, SWAP )

I'm asked for the passphrase for LUKS, but swap isn't activated at boot.

I edit /etc/init/mountall.conf from this:

    exec mountall --daemon $force_fsck $fsck_fix

to this:

    mountall -v $force_fsck $fsck_fix
    swapon -a -v
    exit

Swap is now active at boot, and the "Hibernate" option now appears in the system menu (after enabling hibernate in polkit).

I'm running Raring, but I had to mess around during installation to get encrypted root since the live cd installer doesn't seem to handle this setup.
