I cannot reproduce this issue as described. The setting works as expected for me on Wayland.

Can't reproduce either, on git master or on 6.0.5 from Fedora packages

i'm getting the same issue, the setting "even when en external monitor is connected" is deselected, but when closing my laptop lid it goes immediately to sleep, with my external monitor connected or my TV both using HDMI

Still working perfectly for me here with current git master. Hopefully someone who knows the details of any of the power management stuff can investigate soon.

yeah, i can't reproduce this anymore, maybe it was a kernel bug and got fixed when i updated it?, i'm not gonna mark as fixed because i don't know if my issue were the same

Could be, yeah.

Unfortunately for me, the issue still persists 😟
…I am including my current `uname -a` output:

Jan, what version of Plasma are you running?

plasmashell 6.1.4

I am able to reproduce this reliably on git-master on Solus, HDMI cable to external monitor
I can only reproduce after reboot, not after waking from sleep with the monitor already connected 
I also found a related bug

**Settings**
When laptop lid closed: Sleep
Even with external monitor: unchecked
Security & Privacy -> Screen Locking: "Lock after waking from sleep" is checked

**Steps**
Connected HDMI monitor, restarted
Closed lid before boot
At boot, the login screen was correctly shown on the external monitor
Logged in
System immediately went to sleep. Not just the monitor, the power button on the side of the laptop was pulsing

ALSO, after waking the system using an external keyboard, the desktop loaded, unlocked, without requiring me to log in.

Note: I also saw the system immediately go to sleep after logging out and logging back in. Again, I was not prompted to login after waking from that sleep.

kernel 6.10.6

Hmm, with those settings and steps and also Kernel 6.10.6, I cannot reproduce the issue with a wayland session and a monitor connected using DisplayPort-over-USB-C. Need to try again with an HDMI cable on the same or a different monitor.

Were you logging into a Wayland session or an X11 session? Also what kind of GPU does the laptop have? Mine has a 10th gen Intel HD630 GPU.

I have tested HDMI and USB-C myself and both have the same issue for me

into Wayland  (x11 works correctly)

i am not a linux geek, is this output ok?

I can't trigger this either, logging in with the lid closed works correctly on 6.1 and git master

I can still reliably reproduce this on a Wayland session

KDE Plasma Version: 6.1.80
KDE Frameworks Version: 6.7.0
Qt Version: 6.7.2
Kernel Version: 6.10.11-303.current (64-bit)
Graphics Platform: Wayland
Graphics Processor: AMD Radeon Vega 10 Graphics

Does it only happen right after login after a reboot or also when you already have a session running and then change the setting?

I can only reproduce right after login with a reboot

With these steps the display moves to the HDMI display as expected, with an already running session
1. Have Wayland session running
2. Uncheck “even if external monitor is connected” or choose “do nothing” when lid closed (also tested with lid close: sleep, except if external monitor connected)
3. connect external monitor over HDMI
4. close lid

I can reproduce the bug with the steps given in the OP.

In the logs I don't see any PowerDevil activity before the system suspends. So perhaps it's not PowerDevil putting the system to sleep, or rather PowerDevil failing to prevent the system from going to sleep?

Hi all.
I have news from last time.

In the end, I decided to do a clean (re)install of the system (yah, the upgrade to Ubuntu 24.04 was not downright successful in my case). Since I have a Tuxedo laptop, I'm trying out TUXEDO OS 3, with the following parameters:

KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
Kernel Version: 6.11.0-102007-tuxedo (64-bit)
Graphics Platform: Wayland
Graphics Processor: Mesa Intel® Xe Graphics
Based on Ubuntu: 22.04.5

**...and the problem no longer occurs**. So, maybe something “went wrong” in the original system during the upgrade or …?

PS: I still have the original system temporarily on a secondary drive, so I can add some information for investigation if needed. Just booting into graphics mode doesn't work.

I'm not able to reproduce this on git-master. This may have been fixed by other development work.
Are you still able to reproduce this, Natalie?

I don't see this behaviour anymore:
