What produces the desktop image that is displayed immediately after

When resuming, I see the following in order:

        2. a blank screen

What I would like to do is prevent the actual desktop, or the

Stretch Cinnamon
- Are you using systemd?
Yes, but that is not an admission of preferring systemd. ;-)
- How do you initiate hibernation? Via the desktop or via a keyboard
or chassis button?
By closing the lid, it's a laptop (asus zenbook)

This looks like a race condition in which system is hibernated
before your screen is locked. I saw this for suspend when I let
systemd manage my power button. My solution was to
edit/etc/systemd/logind.conf to set HandlePowerKey=ignore and to let
Xfce handle locking and suspend and Xfce Power Manager / Security /
"Lock screen when system is going for sleep"). I use xscreensaver.
I think you're on to something.  When I CTRL+ATL+L the system, and then
close the lid, the post-hibernation resume works correctly (no screen
leakage).  Unfortunately changing the systemd login settings didn't
seem to have any effect.  I'm comfortable not using systemd on servers,
is it just as straight forward without it on desktops/laptops?

I assume that after changing logind.conf you restarted (or similar) to reload your configuration.

What are your values of these logind.conf settings (commented defaults listed)?:


I have not used it, but you might investigate xss-lock to trigger a screen lock based on a systemd hibernate event. Cinammon should do this for you, but it seems that it does not.
