[David Monniaux <1326446@xxxxxxxxxxxxxxxxxx>]

The current default configuration for Ubuntu is to disable hibernation
and enable suspend in menus because, supposedly, there are some systems
on which hibernation does not work. The maneuver to re-enable
hibernation in menus is nontrivial (requires editing polkit-1 files).

On this laptop (and presumably on other Dell laptops with the similar
SSDs), hibernation works perfectly, and Linux cannot resume from
suspend, needing forced reboot.

Maybe this policy of disabling hibernation in menus is ill-advised.

Title:
  [Dell Latitude E6230] Encrypted SSD does not start on resume from
  suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The system does not wake up properly the SSD when resuming from
  suspend (hibernate works fine).

  It may matter that this SSD has a password to be entered at bootup;
  perhaps it would be necessary for the OS to send this password again
  to the hard drive during resume.
