I am currently testing Xubuntu 16.04 beta. Hibernation does not work
properly.

I ran sudo pm-hibernate, then rebooted.
The hibernation part itself seems to work nice.

Resuming presents the following behaviour :
 - the booting sequence starts
 - the console shows the progress of the resuming process (10%, 20%, etc.)
 - my monitor switches to graphical mode like I would expect, but it then remains black instead of showing my desktop. It does not go to "sleep mode" like it does when the computer is off or the DVI cable is disconnected.

The computer remains responsive, and if music was playing when
hibernation started, it properly resumes. I can also use the keyboard
(to run sudo reboot now, for example). Switching to another virtual
console (Ctrl+Alt+1, Ctrl+Alt+7) does not improve the situation.
