Judging by the absence of the line "Hibernation is possible, Active" in the log when this problem occurs, I think that the execution of systemd- sleep does not reach line 256 in sleep-config.c <https://github.com/systemd/systemd/blob/da4128543ffc5042dc9f6b6f1d22ec72b77b17b3/src/shared /sleep-config.c#L256> which is part of a function named enough_memory_for_hibernation and is indirectly called by line 208 in sleep.c <https://github.com/systemd/systemd/blob/master/src/sleep/sleep.c#L208>.
I will set the SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK environment variable to true as this seems to shortcut this function. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1652499 Title: Cannot hibernate properly ; systemd-sleep hangs Status in linux package in Ubuntu: Confirmed Bug description: 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.
