[SOLVED] System not setup for hibernate, yet went into hibernate

Hey friends,

I don't have a 'resume' entry on my kernel command line. My memory setup is 32gb RAM, half of that for zram, and then a 32gb swapfile. The swapfile is on btrfs on a luks-encrypted volume.

Recently I had my laptop screen closed. This typically goes into sleep mode. Well, I noticed while my laptop was closed that the fans suddenly (some time after closing the lid) turned on and loud. This probably lasted 15 minutes before I decided to inspect what was going on and the SDDM screen was on but I was unable to login. None of the ctrl-alt-f# or REISUB options worked...closing and opening the screen, tapping the power button, etc., nothing actually helped. I was forced to hold the power button down for a long time until it fully powered off.

Upon booting again, it tried to resume from hibernate. Ultimately this failed and treated it like a fresh login.

Why is this happening? Is this merely because I have the 32gb swapfile? Is there a way, at a system level, I can completely disable hibernate? This is actually pretty disruptive as I'd like to be able to safely close the lid and have my laptop simply sleep.

Thanks!

Re: [SOLVED] System not setup for hibernate, yet went into hibernate

check in /etc/systemd/logind.conf

Specifically, the default actions for HandleLidSwitch and SleepOperation

Re: [SOLVED] System not setup for hibernate, yet went into hibernate

Ah, thanks @Seth, looks like the solve is here:

File is /etc/systemd/sleep.conf.d/disable-sleep.conf

[Sleep]
AllowSuspend=no
AllowHibernation=no
AllowHybridSleep=no
AllowSuspendThenHibernate=no
