See the referenced fdo bug why this was added. http://bugs.freedesktop.org/show_bug.cgi?id=23196 Could you provide a better logic to detect when it is safe to hibernate or not? I use no type of encryption so I have zero experience with that and a patch would be most welcome. It's probably also best to take this issue upstream and discuss it there. >> So the output of /proc/swaps and /proc/crypttab would probably be >> helpful. > > /proc/swap: > ---- > Filename Type Size Used Priority > /dev/mapper/hidalgo-swap_1 partition 1048568 117996 -1 > ---- > > /etc/crypttab: > ---- > sda5_crypt /dev/sda5 none luks > ---- -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
