Laptop suspend fails

Help
1

I’m using nixos-unstable on an XPS 15. Suspending used to work, but broke at some point. Unfortunately I don’t suspend often and I don’t currently have a good way to reproduce the issue, so it’s hard to narrow down when it started failing.

The systemctl logs are a bit overwhelming, perhaps someone can help me diagnose?

I’ve seen similar issues recently with my XPS 15 on 19.09, did you upgrade your kernel?

I don’t have a XPS but I have a Latitude 5401, you’ve updated the firmware as well? According to the Arch Wiki the suspend also doesn’t go into the correct sleep state on newer Dells, so I’ve had to do some changes to the machine in my configuration.nix file, though this AFAIK means it hibernates instead of suspends. I haven’t had any issues with it yet on 19.09:

boot.kernelParams = [
  "mem_sleep_default=deep"
];
services.fwupd.enable = true;

Yes, I’m on 5.3.8 #1-NixOS

Not yet, thanks for the pointer! Added those, let’s see how this goes.

One other thing I noticed, which might be related or not, is that ‘sudo halt’ shuts down the system but does not power it off. That’s not as much of a problem though.

Also, to actually update the firmware you have to run fwupdmgr update (I always run fwupdmgr get-updates first but not sure if it is actually required).

It seems like this did the trick! This might be wishful thinking, but non-suspended battery life seems much improved as well!

Haven’t seen any problems since, thanks @sondr3!
