Hello team, Apart from this I found issue with kwin_x11 window manager crash. I have made a bug report to kde team and the team mentioned that it is a bug in window decoration plugin. I am not sure if that is the same causing the same issue here. Please find the below information that I shared to kde team.

Application: kwin_x11 (5.24.7)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-56-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.1 LTS
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:

• What I was doing when the application crashed:
  I have multiple desktop environments such as ubuntu, plasma and ubuntudde. I selected x11 instead of plasma or ubuntu wayland during login as that only the one taking me to ubuntu-dde

• Unusual behavior I noticed:
  As soon as I enter password, desktop loading started with wallpaper. And the dock is still not yet loaded. Warning message popped up as "kwin has crashed. It seems that kwin_x11 has crashed in a row. Please select another display manager from below." I can only see one option i.e kwin_x11

• Custom settings of the application:

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault

Could you try if it also doesn't work in deepin (currently the most recent release is v20.8) instead of ubuntudde? If it's a ubuntudde-only issue, you might want to report the issue to ubuntudde instead of deepin :)

I selected x11 instead of plasma or ubuntu wayland during login as that only the one taking me to ubuntu-dde

That's an issue from deepin side. It should display as deepin or DDE or deepin (x11) instead of just x11. although this issue doesn't relate to the crashing issue.

btw, deepin doesn't use the original kwin made by KDE, dde-kwin/deepin-kwin was used and the executable name is also different (kwin_no_scale) and it requires extra dbus service to work. If ubuntudde is not using dde-kwin then that might be the case.

It is very hard to remove complete OS, time consuming and also I think it effects my data. Also, along with ubuntu, I really like the deepin environment most.

could you please help me to chanage to kwin_no_scale from original kwin made by kde? Below is my machine details.

I don't use ubuntudde or ubuntu in general so sorry I couldn't offer further help. I still recommended consider report the issue to ubuntudde team first since they are maintaining the ubuntudde packages. There are a lot of ongoing changes to dde-kwin so it might need some additional work to ensure dde-kwin works under ubuntu.

Okay. Thanks team, For your response. Your support is highly appreciated. Closing the issue here.
