Re: Hibernate on a Lenovo IdeaPad Yoga 13: XFCE problem?
Sorry I wasn't clear in the previous email. I have hibernation
working from the terminal, but not from XFCE. It is a warning that XFCE
isn't telling the whole story about hibernation. (It may also be a
caution for the Debian Installer folks.)
Thank you for the research.

The swap area does have to be big enough to accept the memory
footprint. However, my swap area + swap file is working just fine for
hibernation.

I seem to be working without a UUID.
root@ideapc:~# cat /etc/initramfs-tools/conf.d/resume
RESUME=/dev/mapper/debian--vg-swap_1

That article has no date on it. The work was done with Ubuntu 12.04, now
almost ten years old. I suspect that a lot of work has gone into making
things easier for the user. Since I already have hibernation working
(from the terminal but not the GUI), I didn't read the article closely.

Does anybody read signatures any more?
