hibernation?

[Neal Becker]

I never use hibernation, but am surprised I don't see it as an option 
anywhere I've looked (alt-ctrl-del, and on the kde main menu "leave")

I manually tried pm-hibernate, which appeared to work, but on restart I just 
got a cold reboot, and see this:

Oct  2 08:10:36 nbecker2 systemd-logind: No resume= argument specified in 
the kernel command line, disabling hibernation.

Either your system doesn't support it, or your user doesn't have permission 
(less likely, esp if Suspend is shown).

(all one line):
qdbus --system org.freedesktop.login1 /org/freedesktop/login1 
org.freedesktop.login1.Manager.CanHibernate

Will tell you if logind thinks your system supports it or not.  If not, most 
common cause is insufficient swap.

and you are sure you did not disable it by intention because auf the 
4.7.x kernels and the KASLR warnings?

However, even if you can hibernate you may not be able to resume.
