DPI Cursor Bridge

A Linux X11 alternative to LittleBigMouse. Independent open-source project, not affiliated with or endorsed by LittleBigMouse.

FEATURES
• Physical Monitor & DPI Calibration Canvas: Reads real X11 RandR physical dimensions (mmwidth, mmheight) and pixel geometries, letting you calibrate diagonal inches, DPI, and vertical physical mm offsets interactively on a scaled millimeter canvas comparing physical vs logical screen layouts.
• Proportional Edge Bridge & Wrap Daemon: Real-time XQueryPointer/XWarpPointer watcher computing exact physical-millimeter crossing coordinates across mismatched-DPI displays (e.g., 4K 27" next to 1080p 24"), automatic Corner-Snag Rescue across dead-edge overhangs, optional horizontal/vertical screen wraparound, and an interactive Crossing Simulator + Bridge Log.
• Daemon Rules, RandR Profiles & Global Hotkey: Automatic RandR topology hash profiles stored persistently in config_dir, configurable polling & speed scaling parameters, and a global daemon toggle hotkey (Ctrl+Alt+B via XGrabKey).

NOTES
• Designed for X11 and XWayland sessions where XQueryPointer, XWarpPointer, and RandR output geometry are exposed.
