DeXtop Mode: Samsung DeX & Android Desktop Mode on Linux & macOS

DeXtop Mode is a modern, cross-platform Python GUI wrapper that launches a virtual second screen displaying your Android smartphone's desktop mode (Samsung DeX, Motorola Ready For, native Android AOSP Desktop Mode, etc.) on Linux distributions (Ubuntu, Debian, Linux Mint, Zorin OS, Pop!_OS) and macOS.

It utilizes the powerful engine of scrcpy in the background to handle control and high-performance video/audio streaming.

🚀 Key Features

• Modern Control Center (GUI): A beautiful CustomTkinter desktop interface in dark mode. No terminal commands required!
• Automated Wireless Debugging (ADB Over Wi-Fi):
  • Integrated Wireless Pairing (Association) dialog with step-by-step guidance.
  • Direct one-click Wi-Fi connection with smart IP & Port auto-filling.
• Display Modes & Custom DPI Scaling:
  • Easily toggle between Secondary Display (DeX Mode) and Main Display Mirroring.
  • Customizable desktop display density (160 DPI standard desktop, 200 DPI, 240 DPI).
• Smart Audio Redirection: Select your preferred output device (e.g. Bluetooth headphones, HDMI, internal PC speakers) dynamically from a dropdown menu using WirePlumber/PipeWire.
• Intelligent Power Management (Anti-Veille):
  • Temporarily disables the smartphone's screen timeout (screen_off_timeout) while DeXtop Mode is running, and restores it automatically when closed.
  • Keeps your computer from sleeping during usage via systemd-inhibit.
  • Turns off the physical smartphone screen to save battery and avoid screen burn-in.
• Automatic & Manual One UI Gesture Repair:
  • Automatically refreshes and restarts the One UI Home launcher (com.sec.android.app.launcher) upon disconnecting to prevent back gesture freezes on Samsung smartphones.
  • Prominent "Repair Phone Gestures (One UI)" button available on both the Connection and Settings tabs for 1-click manual repair anytime.
• Mouse & Keyboard Lock (UHID):
  • Optional relative mouse capturing (UHID) for high precision control, customizable directly in the Settings tab (press LAlt or Super to release).
• Cross-Platform Support (Linux & macOS):
  • Native Debian package (.deb), macOS installer (.dmg), PyPI package (pip install dextop-mode), and pipx launcher.
  • Automatic 1-click dependency installer (Homebrew) on macOS.
  • Includes StartupWMClass matching so the custom icon appears natively in your taskbar / dock while running.
