qdbus: Set a specific brightness to a KDE Plasma session.
$ qdbus ${org-kde-Solid-PowerManagement} ${-org-kde-Solid-PowerManagement-Actions-BrightnessControl} ${org-kde-Solid-PowerManagement-Actions-BrightnessControl-setBrightness} ${5000}
try on your machine

The given command is using the "qdbus" utility in a shell script to interact with the D-Bus (Desktop Bus) system, which allows communication between different processes and applications in Linux.

Let's break down the command and understand each part of it:

  1. qdbus: It is a command-line utility used to interact with D-Bus. It allows you to send messages, retrieve data, and execute methods on various D-Bus interfaces.

  2. ${org-kde-Solid-PowerManagement}: This is the first argument passed to the qdbus command. It represents the D-Bus service path or bus name for KDE's Solid Power Management service. A proper value for this placeholder should be provided, but it's not specified in the given command.

  3. ${-org-kde-Solid-PowerManagement-Actions-BrightnessControl}: This denotes the D-Bus object path for the Brightness Control interface within the Solid Power Management service. Similarly, a correct value should be provided here.

  4. ${org-kde-Solid-PowerManagement-Actions-BrightnessControl-setBrightness}: Refers to the specific D-Bus method being called. In this case, it represents the "setBrightness" method within the Brightness Control interface.

  5. ${5000}: This is the argument passed to the "setBrightness" method. In the given command, the value is "5000," which might represent a brightness level (possibly in a range specific to the application/service being controlled).

To summarize, the command aims to utilize qdbus to interact with the KDE Solid Power Management service and execute the "setBrightness" method on the "Brightness Control" interface with the argument "5000". However, to utilize this command properly, the correct values for the placeholders must be provided.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
