Laptop Lid does not triggers Hibernate successfully anymore.

I could have sworn that I was able to hibernate before, but on my Thinkpad T450s, I randomly can't.

The first thing I did was go into Power Manager and see that suddenly, the dropdowns where Hibernate should be selected were saying Suspend. I don't know if it was like that before, but Suspend certainly is no longer functioning as it should, so I switched to Hibernate. I got a weird message that I'd never seen before about how I need to set up an on-disk swap file in the same partition as my / partition, so I went ahead and did that; I'm on Fedora Linux using BTRFS, which doesn't actually like you doing this and so it makes you set up a new btrfs subvolume and whatnot in order to make it.

Mounting and validating the subvolume:

➜  ~ sudo btrfs subvolume list /
ID 256 gen 121318 top level 5 path home
ID 257 gen 121318 top level 5 path root

After all that, when I close and open my laptop lid, I now get an error message saying "GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Permission denied".

Which now that I type it out, I can maybe see the problem, but if this swap partition is the problem then I guess I'll also ask what I'm supposed to do.

If it isn't, then here's the other information I'm supposed to post:

And at some point while troubleshooting, I switched from grub to systemd-boot. I just enabled everything in systemd's `sleep.conf` and then ran `sudo systemctl daemon-reload`

And above all else: The debug output of `xfce4-power-manager` doesn't tell me anything related to "Permission denied" when I close the lid.

Re: Laptop Lid does not triggers Hibernate successfully anymore.

Hello and welcome.

Try using the "resume=c536c681-f9d7-374c-90d3-8d23aae025c0" kernel parameter to let the kernel know exactly where to find the swap partition. Also make sure your swap space is at least as big as your total system memory.
