[xubuntu-users] hibernation in Xubuntu 17.04

[Rog]

I guess maybe I should eat my own words. My laptop running 14.04 will not 
hibernate. I even tried this:

http://ubuntuhandbook.org/index.php/2014/04/enable-hibernate-ubuntu-14-04/

to no avail. I stopped there as I really don't need to hibernate. I prefer 
suspend and watch my battery power to make sure it won't conk out if the batt 
runs down. I'm usually close to a power source so I can plug-in if I want to 
suspend. I'm guessing that hibernate would be fast since my OS, swap, etc., 
are on an SSD.
