Linux sender (X11/Wayland)

[Viniciusap]

Summary

The sender currently requires Windows 10/11 due to DXGI Desktop Duplication and SendInput. Add a Linux sender so users can control Linux machines from the viewer.

Scope

• Screen capture: X11 via libxcb-shm / XShmGetImage, or Wayland via wlr-screencopy protocol (wlroots compositors) or PipeWire screen capture (GNOME/KDE)
• Input injection: uinput kernel module (/dev/uinput) for mouse and keyboard
• Build target: net10.0 (remove net10.0-windows TFM restriction in Sender.csproj)
• The sender already uses interfaces (IScreenCapturer, IInputInjector) — implement Linux versions and wire them up via DI based on runtime OS detection

Related

• Add macOS support for sender and viewer #1 macOS support — similar architecture, different capture APIs
• Wayland support is harder than X11; an X11-only implementation is a useful first step

Difficulty

High — requires knowledge of Linux display server APIs and native interop.
