[Bug 1652499] [NEW] Cannot hibernate properly ; systemd-sleep hangs

[YS1]

Public bug reported:

Hello,
on recent kernels including 4.4.0-57-generic, I observe more often than not the following behaviour after clicking the Hibernate button in XFCE4 interface :

1. Screen becomes black
2. No hard drive activity, which is suspicious
3. Moving the mouse shows the "locked screen" lightdm prompt
4. Unlocking the session, I get back to it ; things seems to work as usual except the ethernet connection is down
5. ps aux | grep hib shows that there is a  /lib/systemd/systemd-sleep hibernate running
6. if I kill this process, the computer finally hibernates
7. booting the computer again resumes the session (with networking enabled) but with persistent graphical glitches on some parts of the interface, most visibly
  a. in my terminal, all occurrences of the letter b are scrambled
  b. in all windows, the maximise/minimise/close buttons are scrambled.
