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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1326446 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.
