Bug 508859

It's possible that either kwin or the kernel is not doing the right thing in response to lid events and sleep events.  Can you run:

> journalctl -xb 0 > ~/Desktop/boot.log

And then go through it and remove any personal information, and then attach it here? That will help us narrow down what's happening. Thanks.

Thanks for the logs, those are helpful. They do show there are two things happening, as you said. They are unrelated from what I see.

1. systemd-logind is getting the lid open and close events. I see where the lid opened and the system suspends. I see later, the lid closed and there was a wake event. These are all being handled by systemd-logind / the kernel, and as such, are outside of anything KDE controls. I recommend contacting the Fedora folks about that, or Lenovo support (if the laptop came with Fedora installed).

This, at the end of the log, might be pertinent:
```
Aug 27 23:49:36 p14s kernel: ACPI: button: The lid device is not compliant to SW_LID.
```

2. When the lid opens and the display remains blank - I do see some logs that indicate a possible problem with kwin, that we can look into.

During the wake event, this is where KDE is affected, and what is actionable for us:

```

I'm not able to reproduce this on git-master

Moving to kwin since it looks related to the display

This could also be a kerne issue.

Is this still happening
We need to break down if this is kwin or the lockscreen. 

Can you temporarily run:
 - system settings -> screen locking  and unset "lock after waking from sleep"

and see if the issue still appears

The situation seems to have improved a lot:

independent of the setting of the 'lock' option you mentioned, the system wakes up properly after sleep.
This is valid for both manually setting the system to sleep (Meta-L, then sleep) or by closing/opening the laptop lid

Operating System: Fedora Linux 42
KDE Plasma Version: 6.5.80
KDE Frameworks Version: 6.20.0
Qt Version: 6.9.2
Kernel Version: 6.16.11-200.fc42.x86_64 (64-bit)
Graphics Platform: Wayland

But, one problem remains:

Setting the option 
Powermanagement / on battery: when laptop lid closed: 'do nothing'

and then closing the lid, the screen turns dark (i can peek a little bit under the panel without activating the 'lid open' status)

Opening the lid lights up the keyboard status indicators (fn-lock on esc key, mic-mute and speaker-mute LED) but the screen remains dark!
Luckily, i'm at home and can reconnect my thunderbolt-box with an external 4K monitor (i'm typing this on the other screen with the laptop panel still being black)
This is with:   [x] lock after waking from sleep:

So, yes, some improvements,
but still more investigation necessary

and without the lock setting:
 [ ] lock after waking from sleep

there is a change in behavior:
- opening the lid has still a black laptop screen, keyboard LEDs are lit
- plug in TB4 box
Now, the external screen and(!) the laptop panel come back to live

Hope this helps in finding the problem...

Okay, sounds like some sort of drm related issue. Please follow https://invent.kde.org/plasma/kwin/-/wikis/Debugging/Debugging-DRM-issues to get a drm debug log of the display not turning on again - both KWin and dmesg logs could be helpful in figuring out what's happening.
