NixOS freeze on systemd suspend

Help
1

Hi!

Im running Hyprland on NixOS on my laptop with systemd-boot and greetd to start the session automatically. I use swaylock-effects. (i tried sddm to solve this problem but it didn’t fix it so i removed it)

The problem in question is that my laptop freezes when i run systemctl suspend. The laptop sleeps like usual (aka the same config on Arch), but when i wake it up it is totally unresponsive. I can see my lock screen but I cannot move the mouse or enter my password. The screen becomes black if I try to switch TTYs.

My dotfiles are on github if it can help.

Does journalctl --boot -1 give any logs if you reboot after such a freeze?

There’s not much…
I also found out that the time isnt moving on the lockscreen as well.

Hi @Guibi
I’m facing same issue. Were you able to fix it?
