Problem:
- The unix_connect function previously hardcoded /tmp as the directory for the Unix socket path.
- This causes compatibility issues on platforms or specific environments that use a different temporary directory, or even lack access to /tmp entirely.

Actions:
- Imported the tempfile module in unix_connect.
- Updated the X11 Unix socket path generation to dynamically use tempfile.gettempdir().

Result:
- The Unix socket path now correctly adapts to the system's runtime configuration (e.g., OS defaults or TMPDIR environment variables), improving cross-platform compatibility.
