Hello Himasai,

Thank you for your question and for reaching out with your question today.

If you want your GUI automation code to work even when the RDP (Remote Desktop Protocol) session is not in focus or minimized, you can use a technique called headless automation. Headless automation allows you to run your code without the need for a visible GUI.

To achieve this, you can use a library like pyautogui along with a virtual display tool such as Xvfb (X Virtual Framebuffer) on Linux or Windows Subsystem for Linux (WSL) if you're on Windows.

Here's a general outline of the steps you can follow:

1. Install the necessary dependencies:
   - For Linux: Install Xvfb by running `sudo apt-get install xvfb`.
   - For Windows: Set up WSL with a Linux distribution of your choice, and then install Xvfb in the WSL environment.
2. Start the virtual display:    - For Linux: Run `Xvfb :99 -screen 0 1024x768x16 &` to start the virtual display on display number 99.    - For Windows: Launch a WSL terminal and run the same command as above.

3. Set the `DISPLAY` environment variable:- For Linux: Set the `DISPLAY` variable to the virtual display by running `export DISPLAY=:99`.

Note that this approach requires a virtual display to be running, so you'll need to keep the virtual display active for the duration of your automation tasks. Additionally, keep in mind that certain GUI interactions may behave differently in a headless environment compared to a visible GUI.

It's also worth mentioning that if you're using a specific GUI automation framework like Selenium, there may be built-in support for headless execution that you can leverage. Be sure to check the documentation of the framework you're using to see if headless mode is available.
