To use hibernate (or suspend2) requires your system to have a *"tuxonice"* enabled kernel. If you are using such a kernel, then you should see the *suspend2* component in either* "/proc/suspend2"* or "*/sys/power/suspend2". *The kernel patch will allow you to resume your system from your disk if you decide to use suspend2. Unfortunately, the* "tuxonice"* patch for the kernel is not available on its website. This is what its website looks like(not very technical). http://www.tuxonice.net/. I doubt running *"hibernate"* from the console will work. However, there is a github project that offers the patch. https://github.com/pierre/tuxonice-fastboot. I will be checking this out myself. > ---------- Forwarded message ---------- > From: Mike Miller <mbmille...@gmail.com> > Date: Wed, Jun 28, 2017 at 6:45 PM > Subject: hibernation in Xubuntu 17.04 > To: xubuntu-users@lists.ubuntu.com > > > Installation of 17.04 on my laptop was a breeze.
