The command "picom -b" starts the picom compositor with backgrond mode enabled.
Here's a breakdown of the components:
-
"picom" is a compositing manager for X Window System, designed to provide window transparency and various visual effects like fading and shadows. It enhances the overall visual experience on X Window System desktops.
-
The "-b" option stands for "background mode". By using this option, the picom compositor runs in the background as a daemon. This means that it will not tie up the terminal or shell window that executed the command, allowing you to continue using the terminal for other tasks.
So, when you run "picom -b" in a terminal, the picom compositor starts running in the background, providing visual enhancements to your X Window System desktop environment.
