How can I enable 3rd screen in Clear Linux

I have 3 screens of the same brand and model on my desktop computer that I use at home. Previously, I could use these 3 screens on windows 10 in a healthy way. It can switch between screens with the mouse; I could move applications, programs, folders and files by dragging them between screens. I could even use 3 screens in outdoor environments where I was connected with the remote desktop.

I recently started using Clear Linux and I loved it. I tried researching how I can use 3 screens on Clear Linux. I have tried different things from many foreign articles. (Even if I have to format 3156243165 times :D)

As a result, I activated the 3rd screen but I cannot switch with the mouse and it looks like a standalone computer. When I take a screenshot, it only takes screenshot of 2 screens.

My computer has Multi-Monitor iGPU capability and its settings are configured in BIOS. NVIDIA drivers and xorg.conf file have been configured.

I specify my monitor layout for information.

  1. Monitor NVIDIA VGA-0
  2. Monitor NVIDIA HDMI-0
  3. Monitor INTEL VGA ?
