Laptop randomly wakes up from suspend to black screen.

I'm currently running Hyprland on Thinkpad T480, when I open the lid to resume from suspend, the login screen shows up for a second and then turns into unresponsive black screen randomly but sometimes it just wakes up normally. Here's the log, the one before shutdown was when black screen appears and I couldn't do anything.

The log ends in

Jun 19 08:05:45 archlinux systemd-logind[1080]: Power key pressed short.

so it seems to only be the IGP

Jun 19 08:05:33 archlinux tp-auto-kbbl[1084]: Setting brightness to 1
Jun 19 08:05:33 archlinux systemd-sleep[143406]: System returned from sleep operation 'suspend'.
Jun 19 08:05:35 archlinux tp-auto-kbbl[1084]: Setting brightness to 2
Jun 19 08:05:41 archlinux systemd-logind[1080]: Power key pressed short.
Jun 19 08:05:42 archlinux tp-auto-kbbl[1084]: Setting brightness to 1

Is this just a blacklight issue?
Disable/remove tlp & slimbookbattery and avoid using GDM

https://wiki.archlinux.org/title/Intel_ … up_from_S3 recently was a thing. Try to limit the c-states and if that prevents the problem (mind the tlp interference!) you could try the workaround.
Also iirc the LTS kernel wasn't affected by this.

I think they issue was caused by slimbook battery, I tried to disable it, still haven't got any issues since then.

If this pans out to bew true, see https://github.com/Slimbook-Team/slimbo … o-solve-it
Since it's apparently a wrapper/gui for TLP and TLP does runtime control of power states this is gonna be a config thing and maybe a change of the existing slibookbattery configuration will avoid it.
You could also try the behavior w/ just TLP (and manual configuration of that)

I tried without slimbook battery and the issue seems to be solved, or kind of. Instead of freezing when the lid is open, now it wakes up and suspends immediately, I have to press the power button again to wake it up but sometimes the same issue happened after I press the power button. I will go ahead and try without TLP entirely.

FWIW I'm having the same issue, also with a T480. Started about 3 days ago. I'd love to figure out which recent change has caused it.

I'm thinking it's something in the kernel though, I'm not running TLP or any other battery life optimizer that I know about off hand.

Kernel.
Does it also happen w/ the LTS one?
Did you test https://wiki.archlinux.org/title/Intel_ … up_from_S3 ?

Seems like kernel isn't an issue for me, it also happens on LTS kernel. However, the second one seems to fix the issue for me.

Arch Linux
