True, kernel developers should resolve the Secure Boot issue with hibernation, but the development focus is on servers, not laptop computers. Also, hibernation should probably use a dedicated hibernate image file instead of requiring a huge swap partition. That being said, it works regardless of hardware capabilities if you turn off secure boot and just configure a LUKS-encrypted SWAP partition. You should figure this out before you install the OS.

I recommend using hibernate (suspend to disk): your computer will “sleep” for 10 years without draining. The only cost is about 7 seconds to boot on modern hardware. For short interruptions with instant wakeup, you can still use light sleep states.

It combines perfectly with LUKS-encrypted root and swap partitions: your data is safe even if someone steals your computer and swakes it up.
