Hibernation is not meant for quick boot. Hibernation is meant for 
resuming your session.

So basically UEFI is... I am sorry I am just going to say this. Fucking 
this thing up as well. Such a great world we live in.

I also cannot hibernate on this Windows machine (sorry to say). And the 
stupid part of it is that it worked before. What the hell.

In 2014 I still had a system that hibernated just fine in Windows and 
Linux :(.

I depend a lot on standby in a certain sense. I don't hibernate with 
desktops but use standby; and I use hibernation with laptops.

But both now no longer work for me. Maybe the chipsets are too old, or 
the manufacturers do not spend time on keeping these older systems 
running, of course.

But *still* the inability to use standby for me costs in fact a lot of 
electricity because I don't want to lose my work environment all the 
time.

My system runs 24/7 instead of maybe 14/7 because of this reason. That 
is some 10 hours each day at a good number of Watts is perhaps 60 euro 
each year because I can't use standby!!!

Do you mean LUKS? It's not a filesystem. But resume using a standard 
LUKS setup works just fine (when it does work). I know I do (or did) a 
lot of messing about with my system myself, but if we can just 
standardize on something then yes it does work.

But it won't work with "cryptswap" obviously. You need a swap partition 
(on LVM) in an encrypted space (in LUKS) which is simply passed to the 
kernel and I don't know how it works (I'd have to check) but I think 
that after the LUKS is unlocked in order to get to the root filesystem, 
it works just fine.

Yes if you create 1000 different variations, UEFI to deal with, this to 
deal with, that to deal with, yes after a while features go down the 
drain and you can't support the same level of functionality anymore.

Maybe I'm the only one but for me the computer experience has gone 
drastically down the road since 2014.
