Linux Desktop Setup Guide


This post merges several Linux desktop “hardcore” notes into one guide, covering:

  • Switching from GNOME to KDE Plasma on Ubuntu
  • Mounting Proton Drive with Rclone and auto-restart via systemd
  • Fixing SSH private key “bad permissions”
  • Reinstalling and troubleshooting Fcitx5 for Chinese input
  • Setting up dev runtimes (Python, Node/Bun, Go, Rust, Ruby, Java, PHP, C++)

Each section has step-by-step commands and caveats. For the full walkthrough, see the Chinese version of this article.
