Bug 438716

Same issue here on Arch Linux. Setting "even when an external screen is connected" is always on regardless of the setting. This gets more annoying if you start your laptop with the lid closed resulting in it going to sleep immediately after logging in. Not to mention if your laptop has an issue where it cannot wake up from sleep (like mine does sometimes - amdgpu issue) this makes wayland session unusable. The only solution is to set "laptop lid close action" to something else.

I cannot reproduce this behavior. In fact, logging in with the lid closed is how I work around this bug.

I can confirm that this happens to me. i close the laptop lid while an external monitor i plugged in and i immediately get put on Lockscreen, then the laptop suspends. It only happens on the Wayland session, here are my specs:

Since the upgrade to 5.22.4, I notice the same behavior on my Arch Linux system. X11 keeps working fine but the setting "even when an external screen is connected" seems to have no effect on Wayland.

I can confirm this bug. In my case however, the laptop only suspends if the display is connected via HDMI. The laptop doesn't suspend when connected to the same display via an USB-C-Dock (and thus via eDP).
I tried to downgrade Powerdevil to v5.21.0 which didn't fix the problem for me, so the relevant change might have happened somewhere else (KWin maybe?).

Can others that are affected specify how the external display is connected (HDMI/DisplayPort) and test if the bug still occurs when DisplayPort is used?

I am connected with HDMI and I only have an HDMI.

This is Wayland-only, correct?
Does it show "your computer is configured not to suspend while an external monitor is plugged in" in Battery Monitor?

Yes, wayland only and no it doesn't. This also happens if the close lid action is "lock screen", which is not related to suspending.

If it's connected via eDP, the message shows up as expected. If the display is connected via HDMI, the message isn't shown.
Enabling the checkbox "Inhibit automatc sleep and screen locking" manually doesn't have an effect in this case either - the laptop will go to sleep or lock the screen, even if it's checked.
This happens on Wayland only.

> This is Wayland-only, correct?
I cannot reproduce the bug any more, but it definitely did happen on Wayland. I don't remember checking whether it worked on X11.

> Does it show "your computer is configured not to suspend while an external monitor is plugged in" in Battery Monitor?
Yes, it did.

Same issue on Fedora 35 (Kinoite),
this only happens on Wayland, Battery Monitor does not show "your computer is configured not to suspend while an external monitor is plugged in".

I don't know if this will help, but I've had this particular issue only recently (currently KDE Plasma 5.23.4): a few updates ago (can't tell for sure which one, probably 5.23.2 or 3) the only thing that didn't work was that when I selected Shutdown from a Wayland session while the lid was closed, it'd go to Sleep instead; now it goes to sleep anytime the lid is closed, even when I start the Wayland session with the lid already closed

I'm also facing the same issue.

*** Bug 361022 has been marked as a duplicate of this bug. ***

I'm experiencing the same issue on 5.23.5.
The cause of the issue is that the external monitor is reported of an "unknown" type, and so it's not considered as an external monitor.
Basically reverting this fixes the issue:
https://invent.kde.org/plasma/powerdevil/-/commit/d3162725cfffb79da7bb8f276a31a915e3349dab
Of course reverting this will break suspend for the original post of the bug.
A better fix would be to correctly detect the monitor type, but how?
Maybe a possible workaround would be to check if:
 * there's only one "unkown" monitor connected => that's possibly the laptop panel => then suspend
 * there's more than one monitor connected, and one of them is type "unkown" => that's possibly an external monitor => don't suspend

Can you provide the output of kscreendoctor -o and xrandr -q

Maybe there's some exotic connector type that we don't know. The heuristic for identifying monitor types is in https://invent.kde.org/plasma/libkscreen/-/blob/master/backends/utils.cpp

A possibly relevant merge request was started @ https://invent.kde.org/plasma/powerdevil/-/merge_requests/76

Just updated to Plasma 5.24 and the issue has been fixed for me: now closing the laptop lid in a Wayland session doesn't trigger suspend anymore, and selecting Shutdown shuts the laptop down correctly instead of suspending it. Thanks!

Same here.

Oh good!

Is there any chance that 5.24 "fixing" this issue caused a new issue?

Here's why I mention that: https://bugs.kde.org/show_bug.cgi?id=450980

^ Not for me, at least. I've just checked, and suspend to RAM seems to work as expected for my laptop (CPU stays cool even after a few minutes), both on X11 and Wayland, but I have an AMD CPU and GPU (and I'm on Arch, not Manjaro)
