KDE Plasma is the desktop environment developed by the KDE community for Linux and other Unix-like systems, and its login sound is part of the startup experience when a user signs in. As Linux content grew on YouTube, TikTok and Discord, recordings of desktop startups were shared outside the operating system itself. The chime became a shorthand for Linux users in memes and setup tours, similar to other system sounds like the discord notification that people recognise instantly without seeing the screen.
