First logout attempt does not terminate

[Dj-Polyester]

Describe the bug A clear and concise description of what the bug is. If the contents of the subsections do not apply, simply replace the contents with N/A. I assume when the process for the app is running, (without proof) arch based systems require two logout attempts to successfully logout in general. In other words, the first attempt cannot terminate the process hence it fails. The second attempt works. In my current arch based system (Artix) with KDE-plasma, in the first logout attempt, KDE-workspace throws "logout canceled by brightness-controller". Similarly my old system was Manjaro (arch based) with xfce4, which didn't have such notifications but again two attempts were required in the same manner. version 2.3.6 (I checked the init file) To Reproduce Steps to reproduce the behavior:

1. Make sure the app is running in the background
2. Logout (the first attempt should fail) Expected behavior A clear and concise description of what you expected to happen. A single logout attempt should be enough. Many apps such as browsers quit when a corresponding logout/shutdown signal is received. I am not knowledgeable about debian based systems Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Linux 6.6.42-1-lts (Artix)
• DE: KDE Plasma 6.1.3
