Description hawaiananas 2024-12-19 13:54:58 UTC 
Application: plasmashell (6.2.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.8.1
Frameworks Version: 6.9.0
Operating System: Linux 6.12.4-200.fc41.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora Linux 41 (KDE Plasma)"
DrKonqi: 6.2.4 [CoredumpBackend]

-- Information about the crash:
When i work on my notebook which uses the hdmi input of my monitor and than want to switch to my desktop pc which uses the display port input on the same monitor, the monitor stays always blank and wants to go into sleepmode after a few sec.
I figured out when i put in my password without seeing anything the login works and the display gets the wakeup signal, but the kde window manager seems to crash after that.

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault

Comment 1 TraceyC 2024-12-19 20:11:22 UTC 
Thank you for the bug report! I'm not able to reproduce this on git-master. Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

#5  0x00007f440b5aa448 in ??? () at /lib64/libQt6Qml.so.6

Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!



My reproduction steps:
Setup: Laptop with Plasma, monitor with HDMI and DisplayPort inputs. Desktop PC with Windows is connected to DP.
X11 session built from git-master
1. Connect laptop running Plasma to a monitor with HDMI cable, set that as the only display
2. Turn on PC, switch the monitor to the DisplayPort input, wait a few minutes
3. Switch the monitor to HDMI input without turning off the desktop

Result: I saw the login screen normally, there was no crash

User setup:
- Notebook connected to monitor with HDMI, OS unknown
-Desktop pc connected to same monitor with DisplayPort, running Plasma 6.2.4 - experiences the crash
Comment 2 Nate Graham 2024-12-20 19:05:03 UTC 
The non-crash issue is clearly Bug 483163, which is fixed in Plasma 6.2.5. So let's focus on the crash here.

Comment 5 hawaiananas 2025-01-08 15:22:21 UTC 
sry im new to this but i will try to give you all needed info.
The software should be up to date as i install updates on my fedoara 41 2 or 3 times a week.
The kde Control panel currently says Plasma version 6.2.5. (x11)
