Hibernate 18.04

Hi

Or maybe more accurately "Resume" after Hibernate

I've Googled (& DuckDuckGo'ed) for an answer that works, all tests of "if
hibernate should work" are positive

I could Hibernate & resume under 16.04 and the dual booted Win7, but didn't as
that screws access from Ubuntu to Win partition (as win cant read Ubuntu...)

Since I upgraded to 18.04 it stopped working, Hibernate does close down but
after re-boot it's just like a clean cold boot

Samsung NP N110 netbook (if that helps)

You still have a dedicated swap partition that is as big or slightly
bigger than physical RAM, yes?

If you use a swapfile or ZRAM, hibernation will never wake.

Also, as ever, check your firmware is current.

The latest version seems to be from OCT 30,2009 | ver 07D0

Yes
swapon-s & free both show enough (more) swap space than Ram

Yes

Hmm. :-( That's a sod, then. I am out of ideas. Hope for a kernel
upgrade, or switch to 18.10 when it becomes available. That's all I've
got.

I don't use hibernate much and I'm holding off 18.04 as I don't want
GNOME. Now you have me wondering if my laptop will still wake when I'm
compelled to upgrade...

Yes it was one of the Googled & DuckDuckGo'ed results, tried to follow but I
had to skipped the secure boot bit, as it didnĀ“t "seem" to refer to my system,
or is secure boot (now) a prerequisite for hibernation and succsessful resume ?
