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

Setting SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK dos not change anything but this seems logical as this was introduced in a recent version of systemd and does not exist in systemd 229. Creating a /etc/systemd/sleep.conf with SuspendState=mem (to avoid cycling through different suspending modes) doe

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

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

If resume completed - e.g. there is some evidence that it was not a cold boot, but actually previous system session did come back up somewhat - systemd has probably finished its job. Graphical glitches are possibly kernel drivers and/or udev/quirk integration. Assigning to linux for further inves
